Analysis Shows Exposure to Monsanto's Glyphosate-Based Roundup Increases Cancer Risk by More Than 40%
"The future will wonder just what we thought we were doing blanketing the world in this poison."
A far-reaching new scientific analysis found that the weed-killing chemical glyphosate is far more dangerous than U.S. government officials admit, showing a 41 percent increased risk of developing cancer for people who have frequent exposure.
Five scientists at the University of Washington conducted the study--analyzing all published data on glyphosate and its link to non-Hodgkin's lymphoma from 2001 to 2018--and are now "even more convinced" that the chemical is behind many cancer diagnoses, according to Lianne Sheppard, one of the study's authors.
Focusing on people in each study who had high exposure to the herbicide, the researchers concluded that "the link between glyphosate and Non-Hodgkin Lymphoma is stronger than previously reported," said the University in a press statement.
"From a population health point of view there are some real concerns," Sheppard told The Guardian.
Those concerns are compounded by the fact that Monsanto--the maker of the widely-used weedkiller Roundup, which contains glyphosate--and the EPA continue to deny that the chemical causes cancer, even as lawsuits against the company which cite the scientific connection continue to pile up.
Monsanto is currently appealing a court ruling from last August, in which the company was found liable for causing a groundskeeper who frequently used Roundup to develop cancer. The company is facing more than 9,000 other lawsuits as well.
The EPA has argued that studies linking glyphosate to non-Hodgkin's lymphoma are flawed--but as The Guardian reported, that argument may fall apart with the release of the latest analysis:
Three of the study authors were tapped by the EPA as board members for a 2016 scientific advisory panel on glyphosate. The new paper was published by the journal Mutation Research /Reviews in Mutation Research, whose editor in chief is EPA scientist David DeMarini.
The findings are consistent with international researchers' analysis of the connection, study co-author Rachel Shaffer said in a statement.
"This research provides the most up-to-date analysis of glyphosate and its link with Non-Hodgkin Lymphoma, incorporating a 2018 study of more than 54,000 people who work as licensed pesticide applicators," Shaffer said. "These findings are aligned with a prior assessment from the International Agency for Research on Cancer, which classified glyphosate as a 'probable human carcinogen' in 2015."
We are at a crossroads
This country and this world are at a monumental crossroads. In a few short weeks, US voters will have an opportunity to beat back the forces of fascism and confront the billionaires who are rigging the economy, our media system, and our democracy, making it increasingly impossible for ordinary people to get by. We’re not just talking about the election. We’re talking about what must be done once these fascist elements are vanquished from power. We need a bolder set of solutions than what either major party has so far been willing to offer and a working-class movement ready to fight like hell for it. Trump didn't emerge from nowhere. The conditions that fueled MAGA authoritarianism were created by decades of radical neoliberal economic policies and a corrupt political system dominated by corporate interests. They slashed taxes on the super-rich, promising that the benefits would trickle down. They said giveaways to the corporate titans would make life more affordable for the rest of us. It was all bullshit. And when a bitter, betrayed populace searches for someone to blame, right-wing demagogues have little trouble finding scapegoats. People know when they're being lied to, but you won't hear any of this from the corporate media. Only independent journalism—powered and funded by people who believe in building a better world—can deliver truly trustworthy daily news. Our Fall Campaign is underway, and we need your help. To power our newsroom through the rest of the year, we need to raise $125,000 by midnight on October 31. So if you share our vision, please contribute whatever you can to sustain our work. |
