Diarrhea Summer: Brought to You by Trump, Big Ag, and the Climate Crisis
This cyclosporiasis outbreak is a bright red, flashing warning light: Without quick action and systemic changes to our food system, the next outbreak could be much, much worse.
Aug 23, 2026
For many, summer is a time for refreshing salads, burgers with lettuce, and fresh berries. But multiple growing outbreaks of cyclosporiasis are draining that summer fun, forcing people to look at fresh produce and wonder, “Will this give me explosive diarrhea?”
These outbreaks, now making up the biggest in US history, weren’t inevitable. They’re linked to President Donald Trump’s funding cuts, Big Ag’s control of our food supply, and yes, even climate change.
This cyclosporiasis outbreak is a bright red, flashing warning light. Without quick action and systemic changes to our food system, the next outbreak could be much, much worse.
What Brought This Sh*t On?
Cyclosporiasis is an intestinal infection caused by the parasite Cyclospora cayetanensis. It contaminates and lays eggs on produce including leafy greens, raspberries, snow peas, basil, and other herbs. Eating those eggs can cause us intestinal pain, low-grade fever, explosive diarrhea, and other medical problems.
Cyclospora is sending us a dire warning that our leaders must heed: We need to invest in public health, climate change response, and a sustainable, diverse food system that bucks corporate control.
From May 1 to August 4, the Centers for Disease Control and Prevention (CDC) confirmed over 10,000 lab-tested cases of cyclosporiasis and 517 hospitalizations. Forty-seven states are reporting cases, with the largest outbreak spanning 15 states. Michigan health officials have reported over 12,000 cases in that state alone. In August, Michigan reported the first and second deaths from this outbreak.
Handwashing and washing produce aren’t entirely effective in eliminating Cyclospora—only cooking produce to at least 158°F can kill the parasites. That, plus the ongoing confusion on where these outbreaks originated, has contributed to this summer’s continuing unease around leafy greens and other produce.
Overwhelming evidence for the Midwest outbreaks points to shredded iceberg lettuce from Taylor Farms de Mexico. Taylor Farms is not a new name in food safety headlines. In fact, from 2009 to 2026, its products have been implicated in more than a dozen foodborne illness outbreaks, ranging from deadly E. coli outbreaks to Listeria, Cyclospora, and Salmonella.
Just this month, in addition to their connection to the historic Cyclospora outbreak, Taylor Farms is now involved in a Salmonella outbreak affecting 27 states and about 345 people. This summer of sickness highlights the role Taylor Farms has played in sickening thousands of individuals across the United States over the years, with little to no significant repercussions from the federal government.
How Trump’s Cuts Made This CyclosporaOutbreak Worse
The US has established programs designed to study, track, and help contain foodborne illnesses. But in recent years, funding for these programs has failed to keep up with the need. And the Trump administration has only made things worse by slashing staff and funding.
The Trump administration cut key grant and funding programs that state health departments rely on to track foodborne illnesses. Last year, due to staffing cuts, the Administration paused a quality control program conducted through the FDA’s Food Emergency Response Network (FERN) at least through September 2025. This program included quality control work on lab testing for Cyclospora in spinach. It’s unclear whether the program is back up and running today.
Rather than Make America Healthy Again, Trump’s cuts show blatant disregard for food safety and public health.
FERN’s system of federal, state, and local laboratories defends and responds to contamination in the food supply. It tests food samples during large-scale outbreaks to help identify the source of contamination.
Meanwhile, at the CDC, Trump’s budget and staffing cuts have led to downgrades to the FoodNet program. FoodNet tracks long-term trends in foodborne illness rates across 10 states. But with Trump’s cuts, FoodNet was forced to stop tracking 6 of the 8 pathogens it has historically tracked. Cyclospora was 1 of the 6 on the chopping block.
Collectively, those six pathogens cause an estimated 111,000 hospitalizations and 418 deaths each year. One of them, Campylobacter, causes up to $6.8 billion in economic damages every year.
Rather than Make America Healthy Again, Trump’s cuts show blatant disregard for food safety and public health. Quick and comprehensive data collection is an essential line of defense in detecting and containing foodborne illness outbreaks—without it, we’re left fighting in the dark.
Big Ag’s Dominance = More Foodborne Illness
This Cyclospora outbreak also highlights the dangers of our corporate-controlled, highly consolidated food system. Lettuce and leafy greens are common causes of foodborne illness because most are irrigated using polluting substances, or they’re produced near disastrously polluting factory farms.
Factory farms are a huge culprit of this contamination problem. These facilities exist to make raising livestock as cheap as possible for the sake of corporate profits, storing up to a million animals in tight confines. Leafy greens grown near factory farms are regularly exposed to pathogens in the waste that these facilities produce in abundance.
Cyclosporasis in particular spreads via human waste, and Big Ag has long spread sludge from human sewage on agricultural land as fertilizer.
In short, our profit-at-any-cost, highly consolidated food system trades public health for corporate gain.
Moreover, as the industry searches for more water sources, it’s increasingly turned to “recycled” wastewater. While this water moves through treatment plants before it hits fields, that’s often not enough to make it totally pathogen-free. Studies have shown that bacteria and pathogens persist in wastewater after treatment, and research suggests that “using treated wastewater for agricultural irrigation may cause food chain contamination.”
These dangerous business practices aren’t the only way Big Ag is driving more foodborne illness. Taylor Farms, the corporation at the heart of today’s largest Cyclospora outbreaks, has acquired or invested in 10 other companies in just eight years. It runs 22 production facilities in North America and sells 40% of “value-added salads” in the United States.
This consolidation—fewer and bigger companies controlling more of our food—makes our food system even more vulnerable to shocks. Now, Cyclospora shows us the outsized influence a single company can have because of its massive reach. A single corporation can send an illness across the country.
In short, our profit-at-any-cost, highly consolidated food system trades public health for corporate gain.
Climate Change Makes Everything Worse, Including Cyclospora
Since the 1990s, cyclosporiasis outbreaks have occurred each year, typically from May through August. As climate change makes summers hotter and longer, the window for Cyclospora to spread also widens, as the parasite thrives in warm, humid conditions.
Studies also show that climate change and climate disasters will cause more food spoilage and foodborne illnesses. Hotter temperatures promote the growth of pathogens such as Listeria, Campylobacter, and Salmonella, while floods can contaminate food supplies with sewage and agricultural runoff.
Right now, our corporate-dominated food system is utterly unprepared for how climate change will impact our food.
Moreover, as climate change drives more and longer droughts, the US Department of Agriculture will likely encourage farms to turn to wastewater as a solution. The agency has called treated wastewater “the irrigation wave of the future.”
Right now, our corporate-dominated food system is utterly unprepared for how climate change will impact our food. While government agencies recommend we irrigate our crops with wastewater, Trump is demolishing climate and public health programs and funding.
Cyclospora is sending us a dire warning that our leaders must heed: We need to invest in public health, climate change response, and a sustainable, diverse food system that bucks corporate control. Or they’ll guarantee another foodborne illness outbreak, rather than making Americans healthy.

GOP Senate Shit Show: Focusing on Fauci Instead of Cyclospora Diarrhea Disaster
GOP lawmakers would rather relitigate the pandemic than have public attention focused on the epidemic happening on Trump's watch.
Aug 06, 2026
It has taken the Trump administration just eighteen months to turn a seasonal stomach bug into a national epidemic.
Cyclospora, the food borne parasite that causes severe diarrhea, has infected an estimated 18,000 Americans so far this summer—more than six times the number of cases the U.S. typically experiences over a full year.
This surge in case counts represents the largest recorded outbreak of Cyclosporiasis in U.S. history. As of writing, it has led to more than 400 hospitalizations across 45 states. Worse still, Michigan recorded its first two Cyclospora-related deaths earlier this week.
With all this in mind, it makes sense that the Senate Homeland Security and Governmental Affairs Committee recently spent nearly three hours grilling a health official over their response to a disease outbreak…
…until you realize that the topic of discussion was COVID-19 rather than Cyclosporiasis.
On July 29, Congressional Republicans called an oversight hearing to do something they’ve done many times before: ask Dr. Anthony Fauci to explain, once again, where COVID-19 came from.
These COVID-origins hearings have now run for years, generated multiple staff reports from both parties, and reliably produce the same result:
- Republicans accuse Fauci of a cover-up,
- Fauci denies,
- Democrats call the exercise theater,
- Everyone goes home having learned nothing they didn’t already believe going in.
This most recent hearing was no different. Chairman Rand Paul (R-KY) subpoenaed Fauci and the 85-year-old retired scientist, more than three years removed from federal service, declined to answer questions. The only notable part about this go-round was that Fauci invoked his Fifth Amendment right more than a hundred times to avoid responding.
On Thursday, the committee voted—along strict party lines—to hold Fauci in contempt of Congress over his recent testimony.
COVID-19 origin hearings have established themselves a predictable, low-yield use of oversight capacity. That makes it worth asking: why are Republicans calling attention to the issue now?
Oversight hearings involve real and finite resources including a Senate committee’s subpoena power, its staff’s investigative time, and a chair’s agenda-setting authority. To have that congressional attention wasted on an issue both sides have already litigated to exhaustion is revealing—especially when juxtaposed with the fact that not a single Republican has subpoenaed anyone over a historic outbreak that continues to spread with no real end in sight.
The Food and Drug Administration’s current acting commissioner Kyle Diamantas could have easily replaced Fauci in the hot seat. Not just for the agency’s failure to adequately communicate with the public about their cyclospora investigations, but also for his professional history as “corporate lawyer that defended Abbott Laboratories in 2022 for its key role in creating an infant formula crisis.” That’s the same Abbott responsible for the contaminated baby formula that spawned a multiyear criminal investigation by the Department of Justice, which has since been dropped despite having yielded, per the DOJ’s own prosecutors, enough evidence to support criminal charges. According to the Wall Street Journal, that call was made by the DOJ’s “top decision makers,” which in all likelihood included the man the GOP plans to confirm as the country’s top lawyer: Todd Blanche.
White House Office of Management and Budget Director Russell Vought—and his former Department of Government Efficiency co-lead Elon Musk—could have similarly been forced to answer questions about how their brand of “efficiency” has hollowed out federal, state, and local health departments charged with monitoring viral threats and inspecting food facilities. Do the American people not deserve to know that thanks to these cuts, there’s a thousand fewer people overseeing our food supply to ensure instances of cyclosporiasis don’t become widespread outbreaks? Or that the principal national office with cyclospora expertise was dismantled during Musk and Vought’s campaign?
There are ample administration officials to place in the hot seat, but the list of culpable targets extends even further. Taylor Farms’ surreptitious handling of this ongoing tragedy is obviously deserving of microscopic inquiry. People all over the country will not look too fondly on the summer they were forced to eschew their bright salads out of fear of becoming too well acquainted with their bathrooms. But Rand Paul & co. evidently have no desire to satisfy the public’s itch for accountability since Taylor Farms’ CEO Bruce Taylor continues to sit easy even as Americans die. A grim reminder of the privileges that political donations have secured under Trump.
The precedent for achieving this sort of accountability was already set by House Democrats. Two days prior to the Fauci hearing, Rep. Robert Garcia (D-CA)—the Ranking Member of the Committee on Oversight and Government Reform—demanded Bruce Taylor answer questions about his (company’s) role in this outbreak.
Neither the ongoing cyclospora outbreak, nor the next manufactured health emergency under Trump, will be solved by another round of questions for a Biden-era retiree. But Republicans aren’t looking for solutions, they’re looking to shift blame for—and from—a shit-show of their own making.
