Diarrhea Summer: Brought to You by Trump, Big Ag, and the Climate Crisis
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........
