Sen. Cory Booker said it "will overturn President Trump's executive order that prioritizes pesticide company profits over public health and ensure that people who have gotten cancer from glyphosate can seek justice."
On the heels of the US Supreme Court hearing arguments in Monsanto Company v. Durnell, Sens. Martin Heinrich and Cory Booker on Wednesday introduced legislation intended to overturn President Donald Trump's executive order mandating production of the highly contentious weedkiller at the center of that case.
"Since my time serving as a City Council member in Newark, I have seen firsthand the devastating harm caused by toxic chemicals in our communities," Booker (D-NJ) said in a statement. "That is why, this week at a rally in front of the Supreme Court, I stood with cancer survivors, activists, and Make America Healthy Again advocates to protest against providing a liability shield to foreign corporations that are poisoning the American people."
"It is why I filed an amicus brief to the Supreme Court supporting Americans who developed cancer after using a toxic pesticide in a case that will determine whether thousands harmed by glyphosate can have their day in court—and why I am a proud co-sponsor of the No Immunity for Glyphosate Act," he added, "legislation that will overturn President Trump's executive order that prioritizes pesticide company profits over public health and ensure that people who have gotten cancer from glyphosate can seek justice in federal court."
Despite Trump's campaign promise to "Make America Healthy Again," he has frequently served the pesticide industry, including by siding with Bayer—which bought Monsanto in 2018—in the case before the high court, and by signing the February order invoking the Defense Production Act for glyphosate, the active ingredient in Monsanto's Roundup.
Specifically, Trump directed US Secretary of Agriculture Brooke Rollins to ensure "a continued and adequate supply of elemental phosphorus and glyphosate-based herbicides." He also noted that domestic producers are required to comply with his order, and under the federal law he invoked, those doing so have broad legal immunity.
Just before Trump's order, Bayer announced a proposed settlement for the tens of thousands of people who say exposure to Roundup caused their cancer. Still, the company and the US Environmental Protection Agency (EPA) continue to claim glyphosate is safe, despite the World Health Organization's International Agency for Research on Cancer classifying it as probably carcinogenic to humans over a decade ago.
The case before the Supreme Court stems from a lawsuit and a resulting verdict in favor of John Durnell, a Missouri man whose blood cancer is in remission after multiple rounds of chemotherapy. The justices' decision could determine whether many others are able to continue pursuing cases against Bayer. Republicans are also pushing to include a "liability shield" for pesticide manufacturers in the next Farm Bill.
Meanwhile, Booker and Heinrich's (D-NM) bill states that "no federal funds may be obligated or expended to implement, administer, or enforce" Trump's glyphosate order, and "any person, or the estate, survivors, or legal representative of such person, who suffers or has suffered physical injury, illness, disease, or death caused, in whole or in part, by exposure to elemental phosphorus or a glyphosate-based herbicide manufactured, distributed, sold, or supplied within the United States, may bring a civil action in an appropriate district court of the United States against any covered entity."
Heinrich said Wednesday that "juries across the country are looking at the evidence and delivering verdicts: Exposure to glyphosate can cause cancer. The Supreme Court cannot and should not allow these verdicts to be overturned."
"My constituents' health and safety comes first. And I will not stand by while President Trump gives immunity to those who put my constituents' health and safety at risk," he added. "That’s why I’m proud to lead the No Immunity for Glyphosate Act, legislation that will restore accountability, uphold court rulings, and protect the health and well-being of families in New Mexico and across the country."
The bill is also backed by Sens. Ed Markey (D-Mass.), Jeff Merkley (D-Ore.), and Peter Welch (D-Vt.). Reps. Thomas Massie (R-Ky.) and Chellie Pingree (D-Maine) introduced companion legislation in February, just after Trump's order. The lead sponsors in the House of Representatives also are working to strip the immunity shield from the Farm Bill and joined Booker at "The People v. Poison" rally outside the Supreme Court on Monday.
The next day, another House Democrat, Rep. Alexandria Ocasio-Cortez (NY), questioned EPA Administrator Lee Zeldin about the immunity shield in Trump's order, as well as his meeting with Bayer's CEO last year and some related internal emails.
"AOC smoked him in there," Drop Site News reporter Julian Andreone said on social media. "Red-handed."
For decades Roundup has been sold as an effective herbicide, one that was safe for humans and the environment. It isn't.
Mark Twain supposedly once said, "Never let the truth get in the way of a good story," but there is a difference between a good story told in fun and a story (supposedly backed by independent scientific research) that people are led to believe because, well, science is supposed to be true. And so we come to the story of Roundup, the herbicide developed by Monsanto that swept the world because it worked and was the “safe” alternative to widely used weedkillers like Dicamba and 2,4-D,—it was said to be safer than table salt!
Roundup was developed in the 1970s as a non-selective herbicide, meaning it would kill almost any growing plant it touched. It was an effective burn-down herbicide farmers could apply prior to planting, and it assured an almost weed-free field at the beginning of the growing season. Roundup could be used in non-agricultural situations as well, to kill weeds and grass growing in sidewalk and patio cracks, around buildings, etc, but care was needed because, as noted, it was non-target and could kill whatever plant it touched.
For farmers, it worked well, except while it did kill growing weeds, buried weed seeds were not harmed, so a weed-free field at planting time did not ensure a weed-free field throughout the growing season. Weeds would continue to sprout, and more herbicide applications would be needed during the growing season.
Then Monsanto developed their big fix released in 1996, genetically engineered (GE) soybeans resistant to Roundup, followed by GE versions of other commodity crops: corn, cotton, sugar beet, and canola. Over-the-top spraying of these GE crops would kill everything but the crop, and Roundup became one of the most widely used herbicides in the world and GE crops came to dominate world commodity crop production.
Companies like Bayer have to protect their product and their profit even if they have to tell a few lies to do so.
While Monsanto sold Roundup with the slogan, “One spray is all you’ll ever need,” in time, it became clear that some weeds were developing resistance to Roundup and farmers were right back where they started, looking for herbicides that worked consistently. More genetic modifications were made to commodity crops making them resistant to other herbicides, like Dicamba and 2,4-D, the herbicides Roundup was supposed to have replaced. These multiple GE or “stacked” crops could be sprayed with a cocktail of herbicides, hopefully ensuring weed-free fields for the entire growing season.
Farmers are using more herbicide, even on the GE crops, and costs for GE seed have risen much faster than non-GE seed. Of course, the motive was never to reduce the farmer’s production costs or agricultural herbicide use but to increase it—that's where the profit is.
For farmers who didn’t jump on the GE bandwagon, finding non-GE seed is often difficult. Even more onerous, some farmers have found it necessary to plant GE seed as a preventative measure because non-GE crops can be damaged by chemical drift from neighboring GE fields.
So much for effectiveness, what about the safety of Roundup? In 2000 a study was published in the journal Regulatory Toxicology and Pharmacology that deemed the active ingredient in Roundup (glyphosate) was safe and not a human health risk. Since then, that study has been cited consistently as proof of Roundup’s safety. Numerous other studies have shown that glyphosate could cause cancer and that the inert ingredients that are part of the patented Roundup formulation increase the toxicity of glyphosate. Further, the practice of using Roundup as a desiccant on small grain crops (oats, wheat, and barley) prior to harvest puts Roundup directly on grain that enters the human food chain.
Since acquiring Monsanto in 2018, Bayer has paid out about $11 billion to settle almost 100,000 cancer-related lawsuits with approximately 61,000 still pending. In December of 2025 another blow to the claimed safety of Roundup came when the Regulatory Toxicology and Pharmacology journal withdrew the 2000 article that had touted Roundup’s safety. While the study claimed to be independent and peer reviewed, it has come to light that Monsanto's scientists played a significant role in conceiving and writing the article. Oops.
For decades Roundup has been sold as an effective herbicide, one that was safe for humans and the environment, and without which “consequences would be dire.” Companies like Bayer have to protect their product and their profit even if they have to tell a few lies to do so. They claim to produce safe products that help farmers thrive—real independent research refutes that. Bayer and the agribusiness industry may be thriving, but farmers are not and in these times, too few people seem to care that lies are accepted as truth.
"Now that much of the research finding glyphosate poses no cancer risk has been undermined, it is especially outrageous that the Trump administration is seeking to bolster Bayer's case," said one campaigner.
Just two days after President Donald Trump's administration sided with the maker of glyphosate-based Roundup over cancer victims in a US Supreme Court case, the scientific journal Regulatory Toxicology and Pharmacology retracted a landmark 25-year-old study on the pesticide's supposed safety, citing various ethical concerns involving Monsanto.
Bayer, which bought Monsanto in 2018, maintains that the weedkiller can be used safely and is not carcinogenic. However, the company faces thousands of lawsuits from people who developed cancer after exposure to its glyphosate products. The retraction stems from the US litigation, which in 2017 revealed Monsanto correspondence about the study.
While Bayer told the New Lede's Carey Gillam that Monsanto's role in the 2000 study was adequately disclosed, the journal's editor-in-chief, Martin van den Berg, does not agree. He wrote in an explanation for the retraction that "the apparent contributions of Monsanto employees as cowriters to this article were not explicitly mentioned as such in the acknowledgments section."
"This article has been widely regarded as a hallmark paper in the discourse surrounding the carcinogenicity of glyphosate and Roundup," he highlighted. "However, the lack of clarity regarding which parts of the article were authored by Monsanto employees creates uncertainty about the integrity of the conclusions drawn."
Of the study's three named authors—Gary M. Williams, Ian Munro, and Robert Kroes—only Williams is still alive. Van den Berg wrote that he reached out seeking an "explanation for the various concerns," but "did not receive any response."
The paper is reliant on company research. As van den Berg detailed, "the article's conclusions regarding the carcinogenicity of glyphosate are solely based on unpublished studies from Monsanto," and "the authors did not include multiple other long-term chronic toxicity and carcinogenicity studies, that were already done at the time of writing their review in 1999."
"Further correspondence with Monsanto disclosed during litigation indicates that the authors may have received financial compensation from Monsanto for their work on this article, which was not disclosed as such in this publication," he noted.
"The paper had a significant impact on regulatory decision-making regarding glyphosate and Roundup for decades," he continued. "Given its status as a cornerstone in the assessment of glyphosate's safety, it is imperative that the integrity of this review article and its conclusions are not compromised. The concerns specified here necessitate this retraction to preserve the scientific integrity of the journal."
It took years, but finally that Roundup paper ghost-written by Monsanto has been retracted. The whole episode is indicative of a terrible rot that is active in corners of scientific publishing.www.lemonde.fr/en/environme...

Michael Hansen, senior scientist of advocacy at Consumer Reports, emphasized the years between the retraction and the release of documents exposing Monsanto's role in the study. "What took them so long to retract it?" he asked Stacy Malkan of US Right to Know. "The retraction should have happened right after the documents came out."
Van den Berg, who has been in his role since 2019, told Malkan and Le Monde's Stéphane Foucart that he began reviewing the paper after a September article from Alexander Kaurov of New Zealand's Victoria University of Wellington and Naomi Oreskes of Harvard University.
Kaurov and Oreskes' article in the journal Environmental Science and Policy begins by stressing that "corporate ghostwriting is a form of scientific fraud" and goes on to examine the paper's influence—or as they put it, "how corporate authorship shaped two decades of glyphosate safety discourse."
The Netherlands-based van den Berg said that "it simply never ended [up] on my desk being at first primarily a US situation with litigation. The paper of Oreskes triggered it this summer and these authors made an official request and complaint."
He also told Malkan that "if you have more papers regarding Roundup published in RTP with possible problems, let me know."
Although Bayer on Wednesday pointed to the thousands of other studies on glyphosate and "the consensus among regulatory bodies worldwide," the retraction could affect both regulations and ongoing litigation. As Gillam reported:
Brent Wisner, one of the lead lawyers in the Roundup litigation and a key player in getting the internal documents revealed to the public, said the retraction was "a long time coming."
Wisner said the Williams, Kroes, and Munro study was the "quintessential example of how companies like Monsanto could fundamentally undermine the peer-review process through ghostwriting, cherry-picking unpublished studies, and biased interpretations."
"Faced with undisputed evidence concerning how this study was manufactured and then used, for over two decades, to protect glyphosate sales, the editor-in-chief... did the right thing," Wisner said. "While the damage done to the scientific discourse—and the people who were harmed by glyphosate—cannot be undone, it helps rejuvenate some confidence in the otherwise broken peer-review process that corporations have taken advantage of for decades. This garbage ghostwritten study finally got the fate it deserved. Hopefully, journals will now be more vigilant in protecting the impartiality of science on which so many people depend."
Le Monde's Foucart noted Wednesday that the retracted study "is cited around 40 times in the 2015 European expert report that led to the herbicide's reauthorization in 2017."
In the United States, Nathan Donley, environmental health science director at the Center for Biological Diversity—who has been highly critical of the Trump administration's various decisions favoring the pesticide industry that contradict its so-called Make America Healthy Again promises—urged the Environmental Protection Agency (EPA) to take action in response to the retraction.
"The pesticide industry's decades of efforts to hijack the science and manipulate it to boost its profits is finally being exposed," he said in a statement. "The EPA must take immediate action to reassess its finding that glyphosate is not a carcinogen. That means rather than relying on Monsanto's confidential research of its own product, the agency needs to follow the gold standard of independent science established by the World Health Organization in its finding that glyphosate probably causes cancer."
He also pointed to the Monday briefing in which US Solicitor General D. John Sauer urged the country's top court to hear a challenge to a verdict that awarded $1.25 million to a man who claimed Roundup caused him to develop non-Hodgkin lymphoma.
"Now that much of the research finding glyphosate poses no cancer risk has been undermined, it is especially outrageous that the Trump administration is seeking to bolster Bayer's case," Donley said. "Trump promised the American public his administration would protect Americans from dangerous chemicals and pesticides, but now it's throwing its full weight behind Bayer's desire to deny cancer victims their day in court. This is a massive betrayal of the public and an unabashed prioritization of corporate wealth over public health, plain and simple."
An attorney at Food & Water Watch said the DOJ sent a "clear message... to sick Americans harmed by toxic pesticides: Trump has Bayer’s back, not theirs."
The Trump administration is pushing for the US Supreme Court to shield the manufacturer of Roundup from thousands of state lawsuits alleging that its widely used herbicide product causes cancer.
On Monday, US Solicitor General D. John Sauer recommended that the high court agree to hear a challenge to a Missouri jury's verdict in 2023 that awarded $1.25 million to a man named John Durnell, who claimed that the product caused him to develop non-Hodgkin lymphoma.
Bayer, the agribusiness giant that purchased the manufacturer of Roundup, the agribusiness giant Monsanto, in 2018, immediately challenged the verdict.
In 2015, the World Health Organization's International Agency for Research on Cancer (IARC) classified glyphosate, the active ingredient in Roundup, as "probably carcinogenic to humans" based on "limited evidence."
That evidence became less limited in 2019, when a prominent meta-analysis by a team of environmental health researchers found that people exposed to glyphosate at the highest levels had a 41% higher risk of developing non-Hodgkin lymphoma than those who weren't.
There are nearly 4,500 Roundup claims currently pending in federal court, and at least 24 cases have gone to trial since October 2023. They make up just a fraction of the more than 170,000 claims filed.
According to Bloomberg, Bayer has already been forced to pay out more than $10 billion in verdicts and settlements over the product, which has caused a massive drain on the company's stock price.
In what it said was an effort to “manage litigation risk and not because of any safety concerns,” Bayer removed glyphosate-based herbicides from the residential market in 2023, switching to formulas that “rely on alternative active ingredients.”
That didn't stop the lawsuits from coming. Durnell's victory was the first successful case brought against Bayer outside California, the only state that labels the product as carcinogenic. That in Missouri opened the floodgates in other states, and plaintiffs subsequently won sizable payouts in Georgia and Pennsylvania.
But now the Trump administration is trying to help the company skirt further accountability. Sauer, who is tasked with arguing for the government in nearly every Supreme Court case, filed a 24-page brief stating that there is a lack of clarity on whether states have the authority to determine whether Bayer and Monsanto violated the law by failing to warn customers about potential cancer risks from Roundup.
Bayer argues that these cases are preempted by the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA), which forbids states from enacting labeling requirements more stringent than those recommended by the federal government.
Sauer agreed with Bayer, stating in the brief that the US Environmental Protection Agency "has repeatedly determined that glyphosate is not likely to be carcinogenic in humans, and the agency has repeatedly approved Roundup labels that did not contain cancer warnings."
In 2016 and again in 2020, the EPA indeed classified glyphosate as "not likely to be carcinogenic to humans" following agency assessments. However, in 2022, the 9th US Circuit Court of Appeals voided this assessment, finding that the agency applied “inconsistent reasoning” in its review of the science.
Among the justifications for the ruling were that the EPA relied heavily on unpublished, non-peer-reviewed studies submitted to regulators by Monsanto and other companies that manufacture glyphosate. The agency also largely disregarded findings from animal studies included by the IARC, which showed a strong link between glyphosate and cancer.
"The World Health Organization has recognized glyphosate as a probable carcinogen while the EPA continues to twist itself into pretzels to come to the opposite conclusion," Lori Ann Burd, a staff attorney and director of the Center for Biological Diversity's environmental health program, told Common Dreams.
Notably, Health and Human Services Secretary Robert F. Kennedy Jr. built his national profile campaigning against the dangers of pesticides and railing against regulatory capture by big business.
Kennedy served as an attorney for Dewayne Johnson, the first plaintiff to win damages against Monsanto in 2018, where a jury determined that Roundup had contributed to his cancer.
"If my life were a Superman comic, Monsanto would be my Lex Luthor," Kennedy said in a 2020 Facebook post. "I've seen this company as the enemy of every admirable American value."
During Kennedy's 2024 presidential run, he pledged to "ban the worst agricultural chemicals already banned in other countries."
But after he was sworn in as President Donald Trump's HHS Secretary, he began to sing a different tune. As Investigate Midwest noted, his "Make America Healthy Again" commission's introductory report made no mention of glyphosate.
Meanwhile, he reassured the pesticide industry that it had nothing to worry about: "There’s a million farmers who rely on glyphosate. 100% of corn in this country relies on glyphosate. We are not going to do anything to jeopardize that business model," he said during a Senate Appropriations Committee hearing.
The Trump EPA has deregulated toxic chemicals across the board over the past year. It rolled back protections against per- and polyfluoroalkyl substances (PFAS), often referred to as "forever chemicals," in drinking water, which have many documented health risks. It has also declined to ban the widely used insecticide chlorpyrifos, which has been linked to neurodevelopmental disorders in children.
Elizabeth Kucinich, the former director of policy at the Center for Food Safety, described the US Department of Justice's effort to shield Bayer as another "betrayal of MAHA health promises." Her husband, the two-time Democratic presidential candidate Dennis Kucinich, worked as the campaign manager for RFK Jr.'s 2024 presidential bid.
“This is regulatory capture, not public protection,” she said. “This action shields chemical manufacturers from accountability by elevating a captured federal regulatory process over the lived harm of real people. That is anti-life, and it is exactly what millions of MAHA voters believed they were voting against.”
Food & Water Watch staff attorney Dani Replogle said the DOJ filing "encourages the Supreme Court to slam judiciary doors in the faces of cancer patients across the country."
"No political posturing can undo the clear message this brief sends to sick Americans harmed by toxic pesticides," she continued. "Trump has Bayer’s back, not theirs."
While it may be creepy to read an industry-funded dossier on you online, it pales in comparison to what other pesticide industry critics have faced.
As I head back from Cali, Colombia after attending the Convention on Biological Diversity this week, I’ve been thinking a lot about the attempts by countless advocates around the world to take on one of the biggest drivers of biodiversity collapse: toxic pesticides. Reducing the use of pesticides is one of the key ways we can help beneficial insect species rebound, protect vital pollinators, ensure thriving aquatic ecosystems, and much more—all while protecting human health.
With all that we know about the benefits to biodiversity of reducing pesticides, why haven’t we made more progress in tackling these toxic substances? The latest clue came to us last month thanks to an investigation by Lighthouse Reports, which revealed that the Trump administration had used taxpayer dollars to fund a pesticide industry PR operation targeting advocates, journalists, scientists, and UN officials around the world calling for pesticide reforms.
The investigation exposed the details of a private online social network, funded by U.S. government dollars, with detailed profiles of more than 500 people—a kind of Wikipedia-meets-doxxing of pesticide opponents. It showed how the network was activated to block a conference on pesticide reform in East Africa, among other actions.
My interest in the leaked private network is also personal: I’m one of those profiled, attacked for working on numerous reports, articles, and education campaigns on pesticides. In my dossier, I’m described among other things as collaborating on a campaign alleging pesticide companies “use ‘tobacco PR’ tactics to hide health and environmental risk.” Guilty as charged. While it may be creepy to read an industry-funded dossier on you online, it pales in comparison to what other pesticide industry critics have faced.
When you don’t have science on your side, you have to rely on slime.
There’s Dr. Tyrone Hayes, the esteemed UC Berkeley professor, who has persevered through a yearslong campaign to destroy his reputation by the pesticide company Syngenta whose herbicide atrazine Hayes’s exacting research has linked to endocrine disruption in frogs. There’s journalist Carey Gillam who faced a Monsanto-funded public relations onslaught for raising substantive questions about the safety of the company’s banner herbicide product, Roundup. There’s Gary Hooser, former Hawaii State Senator and Kauaʻi County Councilmember who weathered a barrage of industry attacks for his advocacy for common sense pesticide reform—a barrage so effective he lost his seat in office. The list goes on.
Why develop elaborate attacks on journalists and scientists raising serious concerns about your products? It’s simple: When you don’t have science on your side, you have to rely on slime.
This latest exposé does not surprise me, of course, nor many colleagues who are also listed in this private online network. I’ve been tracking industry disinformation and its attacks on those working to raise the alarm about the environmental and human health impacts of pesticides for decades: this is what companies do. They try to defame, marginalize, and silence scientists, journalists, and community advocates who raise concerns about the health harms of their products.
Growing up, I saw this up close. My father, the toxicologist and epidemiologist Marc Lappé, was a professor of medical ethics and a frequent expert witness in legal cases where chemicals were a concern. He died at age 62 of brain cancer. By the time he passed away, I had heard countless tales of his legal wranglings in depositions and on the stand. Cases where he served as an expert witness for lawsuits on behalf of people harmed by exposure to dangerous chemicals, lawsuits against some of the biggest chemical companies in the world.
Thanks to this investigation, we now have another example of how the pesticide industry tries to shift attention away from these very real concerns, even using taxpayer dollars to do it.
The defense attorney’s strategy with my father was always the same: undermine his expertise, rattle his equanimity so juries would trust well-paid lawyers, not my dad. There was the time they quoted an excerpt of one of his journal articles to make it sound like he was contradicting himself, which backfired when he asked the lawyer to read for the jury the rest of the paragraph, putting the words in context and solidifying his point. The worst story was from a trial not long after my stepmother died in a tragic accident, leaving behind my three younger half-siblings. As my dad walked to the stand, one of the defense lawyers said under his breath, “Marc, how was Mother’s Day at your house this year?” Slime indeed.
But while they have the slime, we have the science: We know that many of the pesticides now ubiquitous in industrial agriculture are linked to serious health concerns, from ADHD to infertility, Parkinson’s, depression, a swath of cancers, and more. The insecticide chlorpyrifos is so toxic there are no determined safe levels for children or infants. Paraquat, linked to Parkinson’s, is so acutely deadly a teaspoon of the stuff can kill you—something its largest producer, Syngenta, has known for decades. And, 2,4-D, the defoliant used in the Vietnam War to wipe out forest cover in that country has been linked to birth defects among children there—and in the United States—even decades after the war.
The threat for biodiversity is severe, too. A 2019 comprehensive review of more than 70 studies around the world powerfully tied widespread pesticide use to insect declines worldwide. And, as reported in the Pesticide Atlas (I edited the U.S. edition), despite these known risks, pesticide use is increasing in many regions in the world. In South America, pesticide use went up 484 percent from 1990 to 2017. In Brazil, alone, pesticide sales have shot up nearly 1000% between 1998 and 2008
Thanks to this investigation, we now have another example of how the pesticide industry tries to shift attention away from these very real concerns, even using taxpayer dollars to do it. As I land in Colombia, where tens of thousands are gathered to envision a world conducive to thriving biodiversity, I hope this reporting will remind policymakers to rely on science, not spin.
"With the new formulations of Roundup, Bayer had the opportunity to make us safer, but it did the opposite," one expert said.
Facing tens of thousands of lawsuits after it acquired Monsanto, Bayer promised to remove cancer-linked glyphosate from its commercial Roundup weed killers by 2023. But an analysis published by Friends of the Earth on Tuesday reveals that the replacement is even more dangerous.
The environmental group found that many residential Roundup products still do contain glyphosate, and those that don't have replaced it with a chemical cocktail that is 45 times more toxic to human health following long-term exposure.
"With the new formulations of Roundup, Bayer had the opportunity to make us safer, but it did the opposite," Kendra Klein, deputy director of science for Friends of the Earth, said in a statement. "Bayer's willingness to deceive the public and disregard our health as it continues to cash in on the Roundup brand name is outrageous."
"In short, the new Roundup is not the old Roundup—it's worse."
Roundup weed killer was first commercially released by Monsanto 50 years ago. Since then, tens of thousands of people say they have come down with Non-Hodgkin lymphoma after repeated use of the product and its active ingredient glyphosate, which the World Health Organization's International Agency for Research on Cancer says is "probably carcinogenic to humans." Despite the risk, it is so widely used that it has been found in 80% of a test of U.S. urine samples.
"The human toll of Roundup is enormous—tens of thousands of people have lost their lives and their health because of this toxic weed killer," Klein said.
In response to both legal challenges and popular pressure, Bayer announced in 2021 that it would remove glyphosate from residential Roundup sold in the U.S. within two years.
To track how well Bayer kept that promise, Friends of the Earth assessed the Roundup products for sale at Lowe's and Home Depot—the largest home and garden stores in the U.S.—between June and October of 2024.
It found that seven of the Roundup products for sale still contained glyphosate, while the eight that did not used chemicals "of dramatically greater concern."
Bayer has replaced glyphosate with a combination of four chemicals—fluazifop-P-butyl, triclopyr, diquat dibromide, and imazapic—the latter two of which are banned in the European Union. All four chemicals are even more dangerous to health than glyphosate on average following chronic exposure, according to the Environmental Protection Agency's (EPA) analysis of safety studies. The new ingredients have been linked to kidney and liver damage; reproductive, birth, and development problems; and allergic reactions or irritation that impact the eyes, skin, and respiratory system.
While all four are toxic, one stands out: Diquat dibromide is 200 times more toxic than glyphosate and is considered a "highly hazardous pesticide."
The new ingredients also pose a greater risk to the environment. They are, on average, more likely to threaten bees, birds, worms, and fish and other aquatic life. They are also less likely to break down in the environment, and therefore more likely to infiltrate groundwater and pollute rivers and drinking water.
"In short, the new Roundup is not the old Roundup—it's worse," Friends of the Earth concluded in the report.
The environmental group also criticized Bayer for not providing a warning to consumers about the altered ingredients, as well as lax federal law that does not require pesticide makers to alert shoppers when they change the ingredients of a known brand. While pesticide makers do have to list the active ingredients of a pesticide on the container, the average consumer may not be aware of the relative toxicity of these chemicals. A frequent Roundup user is also likely to assume that anything sold under that brand is similarly toxic to products they have used before.
"Drug companies are not allowed to replace the aspirin in a brand-name pain reliever with oxycontin or fentanyl, and for good reason," Friends of the Earth senior campaigner Sarah Starman said. "It is unconscionable that the Environmental Protection Agency allows this toxic sleight of hand and unethical that Bayer is exposing consumers to dramatically greater risks with no warning."
Friends of the Earth called on Bayer to develop safer chemicals and retire toxic brands like Roundup. At the very least, it urged the company to sell the new formulations under a different brand and warn buyers of the new products' health and environmental risks.
Home and garden retailers, the group argued, should also step up by removing all Roundup products from their stores and online catalogs, or at least selling them with clear warnings of the new risks; phase out toxic pesticides; and offer safer and more organic options.
Finally, the group called on the EPA to toughen its regulations by requiring ingredient-specific safety warnings on commercial pesticides, mandating that new formulations be sold under a new brand, and banning chemicals that harm human health and the environment from consumer products.
"Bayer, like other chemical companies, cannot be trusted to protect our health," Starman said. "We need serious reform at the EPA to ensure that the agency does its duty to protect people and the environment from dangerous pesticides."
"EPA lacks a legal human health assessment of glyphosate to support its current use," said a lawyer for the Center for Food Safety.
Citing research from the U.S. government's own National Institutes of Health, a coalition of environmental and farmworkers groups said Wednesday that the U.S. Environmental Protection Agency is out of excuses for continuing to allow the use of the herbicide glyphosate, which has been linked to cancer in people who are exposed to it.
The Center for Food Safety (CFS) filed a petition with the EPA on behalf of Beyond Pesticides and four farmworkers groups, including Alianza Nacional de Campesinas, saying glyphosate's registration in the U.S. is illegal.
The petition was filed a week after cancer scientists at the NIH published a study in Environmental Health Perspectives, which found that male farmers had "markers of genotoxicity" when they reported high levels of glyphosate use.
The study is only the latest to link glyphosate, the active ingredient in the widely used weedkiller Roundup, with cancer and other health issues. The World Health Organization's International Agency for Research on Cancer warned in 2015 that glyphosate is "probably carcinogenic to humans," and Roundup manufacturer Monsanto—now owned by Bayer—was ordered to pay more than $2.3 billion by juries in 2018 and 2019 for failing to warn the public about the product's risks.
"Farmworker women and their families have experienced the damaging health effects of pesticides for far too long," said Mily Treviño-Sauceda, executive director of Alianza Nacional de Campesinas. "EPA must protect the nation's farmworkers and our environment by immediately suspending and canceling all glyphosate registrations."
Last year, the U.S. Court of Appeals for the 9th Circuit struck down the EPA's claim that glyphosate is safe.
Despite the mounting evidence of the harmful effects of glyphosate, said CFS on Wednesday, "EPA has declined to act."
"EPA lacks a legal human health assessment of glyphosate to support its current use," the group said.
Pegga Mosavi, an attorney at CFS, said the petition provides the Biden administration with "a blueprint... to do what the law and science require and finally cancel glyphosate's registration."
"There is a wealth of scientific evidence demonstrating that glyphosate endangers public health, and poses cancer risks to farmers and other Roundup users," said Mosavi. "Glyphosate formulations are also an environmental hazard and have driven an epidemic of resistant weeds that plague farmers. After last year's court decision, EPA has no legal legs to stand on. EPA must take action now."
Environmental Health Perspectives also published an opinion article by health researchers who found the NIH study should be considered in glyphosate safety evaluations.
"There is really compelling new science out there," Bill Freese, science director at CFS, told The Guardian. "It's becoming increasingly untenable for the agency to deny the cancer hazard."
The group said the EPA should suspend the use of glyphosate—which is already banned for household use in France, the Netherlands, and Belgium, and for public use in Germany—until its registration can be canceled or the agency can prove the herbicide meets required safety standards under the Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA).
"In accordance with FIFRA, EPA can register a pesticide only upon determining that it will cause no unreasonable adverse effects on the environment when used in accordance with widespread and commonly recognized practice," reads the executive summary of the petition. "Glyphosate remains registered despite no demonstration by EPA that it can meet the required FIFRA safety standard for this herbicide's currently approved uses. In other words, glyphosate as it's currently used has no legal safety assessment on record."
Freese noted that in the past, the EPA acknowledged glyphosate's adverse effects on the liver, kidneys, reproductive system, and its link to cancer.
"But as Monsanto sought ever wider uses for its blockbuster herbicide," said Freese, EPA consigned those incriminating studies to regulatory oblivion, thus facilitating greater use, even as independent scientists confirmed the harms EPA now denies."
With the specter of eucalyptus trees engineered for pesticide resistance and the Biden administration’s embrace of false solutions to climate change, the balance is being further tipped in favor of the pulp and paper industry.
Valued for its termite-resistant wood for building purposes, pulp to create products like writing and toilet paper, and its oil, which has numerous health and household benefits, the eucalyptus tree generates big business worldwide. Native to Australia and Tasmania, the prehistoric tree has been planted in such volumes that eucalyptus plantations cover some 25 million hectares around the globe—larger than the entire land area of the United Kingdom. By 2028, according to forecasts, the global eucalyptus oil market is projected to exceed $213 million, while the worldwide market for eucalyptus pulp will expand to nearly $17 billion.
But the eucalyptus industry has a dark side. Eucalyptus plantations growing in regions spanning South America, southern Africa, southern Europe, and Australia have significant detrimental impacts on local communities and biodiversity. Communities located near eucalyptus plantations are likely to face water shortages—as these plantations utilize huge amounts of water—and pollution from agrochemicals, including exposure to glyphosate, which has been linked to various health problems, including increased cancer risk.
In addition, the presence of eucalyptus trees’ leaves and roots hinders the growth of other plants beneath them because they contain a biocidal oil that inhibits the survival and decomposition of most soil bacteria that come into contact with them.
In eastern Brazil, eukalyptus plantations have replaced the diverse and endemic Atlantic Forest ecosystem, with some municipalities seeing nearly three-quarters of their land area being covered by eucalyptus plantations.
Brazil is the world’s largest eucalyptus producer. With an estimated 7.6 million hectares of eucalyptus plantations, Brazil maintains 30% of the world’s total eucalyptus trees. In eastern Brazil, particularly in the states of Bahia and Espírito Santo, these plantations have replaced the diverse and endemic Atlantic Forest ecosystem, with some municipalities seeing nearly three-quarters of their land area being covered by eucalyptus plantations. Large corporations such as Suzano, Fibria, and Veracel dominate this industry, exporting eucalyptus as pulp for manufacturing products like toilet paper.

During the delegation’s official meeting, Moisés Savian, secretary of Brazil’s Ministry of Agrarian Development, identified corporate interests as the driving force behind the push for GE eucalyptus. “It makes no sense in my vision to have a transgenic eucalyptus associated with glyphosate,” stated Savian.

Genetically engineered (GE) varieties of eucalyptus trees are poised to exacerbate a new wave of ecological and social destruction. Brazil has approved seven varieties of genetically engineered trees. Current plantations rob regions of water, destroy wildlife habitat, and transform large swaths of land within the Cerrado—an expansive, biodiverse tropical biome situated in eastern Brazil—into unnatural, destructive monoculture farms: rows upon rows of non-native eucalyptus trees without vegetation in their understory. Many traditional communities and Indigenous people have opposed the spread of these plantations in the country.
Varieties of GE eucalyptus are pesticide-resistant and are likely to increase the use of toxic chemicals such as Roundup, the glyphosate-based weedkiller developed by Monsanto in the 1970s, which is the world’s most used herbicide—and was acquired by Bayer in 2018. Other engineered traits, such as increased growth rates, could make the trees more profitable for the pulp and paper industry but significantly more harmful to the environment.
The Campaign to STOP GE Trees is an international alliance of organizations working to halt the introduction of genetically engineered trees into the natural environment to prevent ecological destruction and harm to local communities. It is an initiative of our U.S.-based organization, Global Justice Ecology Project (GJEP), with support from the Uruguay-based World Rainforest Movement, which advances the cause of social justice in the forests.
An international delegation of the campaign, which was organized by GJEP, traveled to Brazil in July 2023 to meet with Indigenous and quilombola communities (descendants of escaped Afro-Brazilian enslaved people), members of the Landless Workers’ Movement (Movimento dos Trabalhadores Rurais Sem Terra, or MST, in Portuguese), government ministries, and academics. The delegation’s goal was to learn about the history of resistance against the pulp and paper industry in the country and discuss how herbicide-resistant genetically engineered varieties of eucalyptus trees could increase the use of toxic herbicides and amplify ecological degradation, health impacts, and social injustice.
FASE (Federação de Órgãos para Assistência Social e Educacional), a group that has been supporting communities opposing eucalyptus plantations for a decade, organized the logistics of the delegation, which included representatives from Argentina, Canada, Chile, Ireland, Japan, New Zealand, and the United States. Local representatives joined the delegation as it visited several Brazilian ministries to register official demands and testimonies from quilombola and MST community members from northern Espírito Santo and southern Bahia about the devastating impacts of eucalyptus plantations as well as new threats posed by GE eucalyptus trees.
“It makes no sense in my vision to have a transgenic eucalyptus associated with glyphosate.”
“The demands that we recorded were from several MST communities that we met with that are doing important agroecological work and have a whole agroecological school training people in the region about how to grow organically,” said Anne Petermann, international coordinator of the Campaign to STOP GE Trees. She noted that “there were also statements from members of traditional quilombola communities in that region who are suffering, very directly, the impacts of eucalyptus plantations.”
The delegation also officially presented petitions from Rainforest Rescue, an environmental nonprofit based in Hamburg, Germany, signed by more than 100,000 people opposing the release of GE eucalyptus in Brazil to the ministries and Brazilian National Technical Commission on Biosafety.
During the delegation’s official meeting, Moisés Savian, secretary of Brazil’s Ministry of Agrarian Development, identified corporate interests driving the push for GE eucalyptus.
“It makes no sense in my vision to have a transgenic [eucalyptus] associated with glyphosate,” stated Savian. His comments highlighted the increasingly ubiquitous and dangerous as well as probable cancer-causing herbicide Roundup. “It is much more linked to market interests of the corporations that want to sell herbicide,” the secretary noted.
Another motivation behind the push for GE eucalyptus is the Kafkaesque incentive of receiving carbon credits for planting trees. Corporations like Suzano—which has been called the “world’s largest pulp exporter”—can be rewarded for planting enormous industrial tree monocultures—since they are technically planting trees, they are eligible for carbon credits—even though they first clear-cut and remove the carbon-dense native forests, which release vast amounts of carbon from the forest and the soil.
The pulp industry in Brazil has accelerated the growth rate of their eucalyptus trees. This is increasing the already enormous demands on water resources. So problematic is the expansion of eucalyptus monocultures on the hydrology and biodiversity of regions that they are often called “green deserts.”
“They look green from a distance but are extremely fast-growing trees planted in perfect rows and columns optimal for mechanical harvesting. The huge plantations do not harbor wildlife, and the only biodiversity you find in them is ants and termites,” explained Petermann, who led the delegation that traveled to Brazil.
An expanding landscape of monoculture industrial tree plantations in Brazil—which rob the forests of biodiversity, displace communities and wildlife, and deplete regions of water resources—epitomizes the eco-swindle of carbon credits.
One of the most insidious trends in false solutions to climate change is the idea that living or biological carbon can offset fossil fuel carbon. An expanding landscape of monoculture industrial tree plantations in Brazil—which rob the forests of biodiversity, displace communities and wildlife, and deplete regions of water resources—epitomizes the eco-swindle of carbon credits.
João, a member of a quilombola community, told the delegation that when eucalyptus started being planted in Espírito Santo and Bahia, “they removed the native plant cover and all the nutrients from the soil. People [here] used to do agroforestry, would use cover crops, [and would] let the land rest—but now, with eucalyptus, there is no rest for the soil.” The total eucalyptus plantation area in Bahia is estimated to be about 658,000 hectares, positioning it as the country’s third-largest contributor to industrially cultivated eucalyptus.
Dr. Ricarda Steinbrecher, a biologist from the University of London who attended a forum hosted by the delegation, warned of unintended consequences of genetically engineered trees, stating that “the risks of GE trees is extremely high in terms of the impact on biodiversity, the people living around it, and the global ecosystem and climate.”
Not only are current eucalyptus plantations destructive, but the premise that they are superior to natural forests for capturing carbon is also unsound. In 2020, experts published a letter with the Institute of Physics stating that “forests are superior to, and irreplaceable by, plantations as agents of terrestrial C [carbon] sequestration.” They are harvested with incredibly short growing cycles for pulp and paper production, which releases the carbon back into the atmosphere. But the scheme is profitable for Suzano and other pulp companies since they profit from the production of pulp and paper as well as carbon credits for planting trees.
Brazil is home to numerous biomes, the most famous of which is the Amazon forest. Known as “the lungs of the Earth” for the massive amounts of carbon dioxide the forest inhales and the oxygen it exhales, the Amazon is the focus of many conservation initiatives and agreements.
In early August 2023, Brazilian President Luiz Inácio Lula da Silva hosted the Amazon Summit in Belém, the capital of the Brazilian state of Pará, during which another conservation agreement was launched. The eight nations party to the Amazon Cooperation Treaty (ACT) released the Belém Declaration, a document aimed to unify the shared objectives of the signatory nations, which are focused on preserving the Amazon and the rights of Indigenous people who live in it. The United Nations Climate Change Conference (COP30 ) is slated to meet in Belém in 2025.
In a press release, however, the Center for International Environmental Law (CIEL) stated that the Belém Declaration fell short of commitments to end deforestation in the Amazon and failed to address the issues related to the continued use of fossil fuels.
Nikki Reisch, director of CIEL’s Climate and Energy Program, stated:
The Belém Declaration does not commit… to ending deforestation by 2030, or to addressing the primary, intersecting drivers of rainforest loss—industrial agriculture and the extractive and destructive industries that expose primary forests to land conversion.
Glaringly absent from the declaration is any mention of the threat that continued production and use of oil and gas poses to the Amazon and the ecosystems, communities, and climate that depend on it. Instead, exploration and development of new oil and gas projects continue—even at the mouth of the Amazon itself—directly undercutting leaders’ pledges to prevent the region from reaching the point of no return. Allowing expansion of fossil fuel extraction in the Amazon is incompatible with human rights, including Indigenous Peoples’ rights, biodiversity protection, and climate goals.
Similar deference to industry interests plagues the Cerrado, where eucalyptus plantations and agribusiness continue to run roughshod over Indigenous and traditional communities and destroy a lesser-known but equally precarious natural ecological system regardless of ostensible ecological concerns and overtures.

As the global demand for paper pulp continues to climb, Brazil is expected to be the site of the most significant expansion of these production facilities in South America.
Two regions that the Campaign to STOP GE Trees’ delegation are likely to face the negative impacts of the tremendous growth of eucalyptus plantations to feed the pulp and paper industry.
Quilombola communities the delegation visited stated that in Espírito Santo, most of the municipal land has been turned into plantations by Suzano. They also explained that tax incentives and infrastructure investment in the Três Lagoas region by local and federal governments seek to attract investments by the pulp and paper industry to the state of Mato Grosso do Sul, where much of the native Cerrado forest has been converted to eucalyptus plantation in the past decade.
It is so lucrative that Suzano is building the world’s largest pulp and paper mill in Mato Grosso do Sul. The enormous facility is being built by 10,000 workers, most of whom are stacked in nearby man camps. The mill is expected to employ 10,000 people when completed. The Cerrado Project, as Suzano has deemed it, is in a rural town that has a population of nearly 25,000. The project threatens grave environmental damage to natural habitat and biodiversity, water and air, and a devastatingly precipitous population influx.
Additionally, the Chilean corporation Arauco is planning an even larger mill in Mato Grosso do Sul after the scheduled completion of Suzano’s behemoth.
Land sovereignty of traditional communities has been a politically charged issue in Brazil, and the encroachment on lands belonging to traditional and Indigenous communities by agribusiness was a theme that the delegation heard repeated during its travels through Brazil, including in the affected areas of Espírito Santo, southern Bahia, and Mato Grosso do Sul. Born out of Brazil’s colonial past and decades of military dictatorship, land distributions in the country are highly inequitable. Agribusiness interests have been incredibly aggressive in the past and continue with this trend currently.
“What made us lose our land, our culture, was all those persecutions by agribusiness,” stated José De Souza, an instructor at the Indigenous Ofaié school in Mato Grosso do Sul. The Ofaié was “once a large people,” he said, noting that such agribusiness pressures almost made “them extinct.” Once having a population of tens of thousands, the Ofaié now live on a mere 45 hectares after being forcibly relocated twice. “It’s not an ended thing,” said Souza. “They destroyed our forests and water.” The school where Souza teaches emphasizes Ofaié culture and language in classes often taught outside in the open. The Ofaié land is small but is an oasis of native forest hemmed in by vast stretches of industrial monoculture plantations.

Eucalyptus is as central to the Ofaié land struggle as it is to the MST, one of the most significant movements in South America. The group has nearly 2 million members, with hundreds of thousands of Brazil’s poor living in MST camps as farmers. The MST seeks to reverse Brazil’s profound inequality of land distribution by occupying land for communal farms.
The movement is a lightning rod of controversy in Brasilia, with lawmakers aligned with former Brazilian President Jair Bolsonaro trying to outlaw the movement. Still, judges have often accepted the MST’s interpretation of Brazilian law that allows unproductive land to be taken. The MST has occasionally included eucalyptus plantations as meeting the definition of “unproductive” and has occupied and repurposed them for communal farms.
The movement has been so successful in its occupation strategy that it is estimated that 460,000 families now live in encampments started by the campaign. The MST is forward leaning with an eye to the future with agroecology schools that teach how to grow crops and food using agroecological methods. They are now the largest exporters of organic rice in Latin America.As the MST, Indigenous people, and traditional communities in Brazil struggle against the spread of industrial eucalyptus plantations, the Biden administration is reportedly funding its expansion.
According to a June 2023 article on Mongabay, “Biden promised funds from the U.S. International Development Finance Corporation to conserve the Amazon and other critical Latin American biomes.” Yet according to findings published by Mongabay, the debt investment, if approved by Congress, will primarily “be funneled into mass-produced eucalyptus in Brazil’s Cerrado savanna.”
Mongabay reported that $50 million of the funding would go to Timberland Investment Group’s (TIG) plan to expand its “planted forest operations,” which located its newest office near Suzano’s Cerrado Project in Mato Grosso do Sul.
During the delegation’s visit to Brazil’s capital, Brasilia, to meet with ministers and lawmakers, Indigenous peoples held a large demonstration to oppose a proposal, PL 490, a law its supporters claim would bring certainty and fairness to land disputes in Brazil. Opponents, however, argue that the proposal would actually reverse hard-fought gains by Indigenous communities to have their land rights officially recognized.
Proposed by Bolsonaro-aligned lawmakers, PL 490 would reset Indigenous land claims to October 1988—when the current Brazilian Constitution was adopted after the military dictatorship. Since the lands were taken during the dictatorship, this is a land-grabbing ruse by extractive industries seeking to deny claims of land rights by Indigenous groups and even to erase gains they had made in the past. The Lower House of Congress gave its approval to this bill in May 2023.
The push for PL 490 underscores how land sovereignty is a fundamental issue in Brazilian politics and is inextricably linked to the country’s environment and the rights of traditional communities. Monoculture eucalyptus plantations play a central role in the contest over land rights, an issue central to Brazilian politics and ultimately connected to the rights of traditional communities and the world’s environmental health. With the specter of eucalyptus trees engineered for pesticide resistance and the Biden administration’s embrace of false solutions to climate change, the balance is being further tipped in favor of the pulp and paper industry in that fight.
“As Brazil goes, so does the world when it comes to the use of GE-engineered eucalyptus,” said Petermann. “The significance of the loss of the Cerrado to GE eucalyptus plantations cannot be overstated.”

Environmental and public health advocates renewed calls to ban glyphosate after a recently published U.S. report revealed the cancer-linked herbicide--which is the active ingredient in Bayer's popular Roundup weedkiller--was found in the urine of more than 80% of study participants.
" Monsanto lobbyists achieved the full-scale poisoning of our planet for profit."
Of the 2,310 urine samples taken from children and adults for the U.S. Centers for Disease Control and Prevention's National Health and Nutrition Examination Survey, 1,885 contained detectable amounts of glyphosate.
"Ban glyphosate," tweeted the Massachusetts-based Berkshire Environmental Action Team in response to the study. "This chemical should not be in our bodies."
David Nickarz, an activist and former Green Party of Manitoba president, tweeted: "Roundup is polluting our bodies and giving us cancer. Why haven't we banned this stuff yet?"
According to The Guardian:
Both the amount and prevalence of glyphosate found in human urine has been rising steadily since the 1990s when Monsanto Co. introduced genetically engineered crops designed to be sprayed directly with Roundup, according to research published in 2017 by University of California San Diego School of Medicine researchers...
Residues of glyphosate have been documented in an array of popular foods made with crops sprayed with glyphosate, including baby food. The primary route of exposure for children is through the diet.
Last month, the U.S. 9th Circuit Court of Appeals ordered the Environmental Protection Agency to review its assessment that glyphosate likely poses "no unreasonable risk" to human health or the environment.
According to the EPA, there is "no evidence that glyphosate causes cancer in humans," a conclusion shared by the European Food Safety Authority--which nevertheless warns that the herbicide causes "serious eye damage" and is "toxic to aquatic life."
However, the World Health Organization's International Agency for Research on Cancer said in 2015 that glyphosate is "probably carcinogenic to humans," while researchers at the University of Washington published a 2019 study showing that using the herbicide increased the risk of non-Hodgkin's lymphoma by 41%.
In 2018 and 2019, three San Francisco-area juries ordered Monsanto--which was acquired by Bayer AG in 2018--to pay more than $2.3 billion dollars in combined damages for failing to adequately warn consumers about glyphosate's cancer risks, although all three judgments were later reduced on appeal.
In 2020, Bayer agreed to pay over $10 billion to settle claims that Roundup exposure caused plaintiffs' cancers. Bayer said the settlement affected 75% of Roundup-related litigation, which involved approximately 125,000 claims.
Bayer announced last July that it would end U.S. sales of its market-leading Roundup home and garden glyphosate-based herbicide by 2023.
A federal appeals court on Friday issued a ruling on the weedkiller glyphosate that the coalition involved with the case called "a historic victory for farmworkers and the environment."
"EPA's failure to act on the science... has real-world adverse health consequences for farmworkers, the public, and ecosystems."
The 9th U.S. Circuit Court of Appeals ordered the Environmental Protection Agency (EPA) to review its conclusions about the safety of glyphosate, the active ingredient in Roundup, a popular herbicide created by Monsanto--which Bayer acquired in 2018.
The EPA "recently assessed whether glyphosate poses 'any unreasonable risk to man or the environment' and answered, for the most part, 'no,'" the 54-page opinion explains, referring to the agency's widely criticized decision from January 2020.
"A group of petitioners challenged EPA's decision, arguing, among other things, that EPA did not adequately consider whether glyphosate causes cancer and shirked its duties under the Endangered Species Act," the ruling continues. "We agree and remand to the agency for further consideration."
The organizations behind the challenge celebrated the court's 3-0 ruling, which Amy van Saun--a senior attorney with Center for Food Safety and lead counsel in the case--said "gives voice to those who suffer from glyphosate's cancer, non-Hodgkin's lymphoma."
"EPA's 'no cancer' risk conclusion did not stand up to scrutiny," she added. "Today is a major victory for farmworkers and others exposed to glyphosate. Imperiled wildlife also won today, as the court agreed that EPA needed to ensure the safety of endangered species before greenlighting glyphosate."
Jeannie Economos, Pesticide Safety and Environmental Health Project coordinator at the Farmworker Association of Florida, a plaintiff in the case, also applauded the "significant decision."
"While it comes too late for many farmworkers and landscapers who suffer after glyphosate exposure," she said, "we are grateful for the court's ruling, and hope that now EPA will act quickly to protect future workers from illness and disease resulting from this toxic pesticide."
Leaders at other groups that took on the EPA over what the court concluded was a "flawed" analysis of glyphosate expressed hope that the ruling will lead to safer farming practices.
"EPA's failure to act on the science, as detailed in the litigation, has real-world adverse health consequences for farmworkers, the public, and ecosystems," said Jay Feldman, executive director of Beyond Pesticides.
"Because of this lawsuit, the agency's obstruction of the regulatory process will not be allowed to stand," Feldman added, "and EPA should start shifting food production to available alternative non- and less-toxic practices and materials that meet its statutory duty."
Rural Coalition chairperson John Zippert declared that "we need to halt glyphosate's devastating impact on the farmworkers and farmers who suffer the deepest consequences of exposure."
"This decision," he added, "will hopefully hasten the transition to farming and gardening methods and practices that increase resilience, protecting our children, our planet, and all those who feed us."
As E&E News noted Friday:
EPA's finding on the human health risk of glyphosate is at the heart of Monsanto Co.'s Supreme Court petition asking the justices to overturn a landmark $25 million jury verdict in favor of a California resident who developed non-Hodgkin's lymphoma after years of using Roundup.
The Supreme Court could accept or reject the petition from Monsanto, now owned by Bayer AG, as soon as next week. A grant and subsequent ruling in the company's favor in Monsanto v. Hardeman could potentially upend thousands of similar lawsuits over the company's failure to warn about the product's cancer risks.
In a lengthy statement responding to the appelate court ruling on Friday, Bayer said that "we believe that the U.S. EPA will continue to conclude, as it and other regulators have consistently concluded for more than four decades, that glyphosate-based herbicides can be used safely and are not carcinogenic, and we are committed to working with the agency to minimize the environmental impacts of our products."
The company pledged to "continue to participate in EPA's public process to help ensure the agency can make fully informed science-based decisions that are protective of listed species and critical habitats."
Bayer announced in July 2021--just over three years after acquiring Monsanto--various moves to "help close the door on this litigation and ensure that any claims brought by individuals who use Roundup in the future are few in number and unlikely to succeed."
Those steps include ending the sale of glyphosate-based products such as Roundup for the U.S. residential lawn and garden market beginning in 2023--a development that the Center for Food Safety and other groups also welcomed as a huge win.
