The cyclospora outbreak 2026 is no longer just a food-safety case file. A CBS News poll found that about 40 percent of Americans say they are buying or eating less produce as federal officials investigate a record wave of diarrheal illness tied in part to fresh food.
The Food and Drug Administration says it is investigating six foodborne illness outbreaks caused by Cyclospora, a one-celled parasite. The Centers for Disease Control and Prevention has counted more than 11,500 confirmed and probable cases across 41 states, with more than 300 people hospitalized. The CDC figure is likely incomplete because foodborne illnesses are often missed unless people seek care and get tested.
The largest outbreak has been linked by the FDA to Taylor Farms iceberg lettuce sold at Taco Bell restaurants and other companies. That outbreak has affected thousands of people across nine states, according to the FDA, expanding from five states identified the previous week. Michigan health officials reported 9,253 cases as of July 27. The FDA has not identified a food source for the other five outbreaks.
What is causing the Cyclospora outbreak?
Cyclospora spreads when microscopic parasite eggs from human feces contaminate food or water. Past U.S. outbreaks have been associated with produce including leafy greens, basil, cilantro, snow peas, green onions and raspberries, according to federal public health information cited by the FDA and CDC.
That mechanism makes the current outbreak awkward for Health Secretary Robert F. Kennedy Jr., who has made eating more “real food,” including fresh fruits and vegetables, a central part of his health agenda. The CBS News poll found only 4 percent of Americans said they were eating more produce in line with that message during the outbreak.
The outbreak has also drawn scrutiny because food safety agencies have fewer people than before. CBS News has reported that, under Kennedy’s leadership, the CDC has lost about 25 percent of its staff and the FDA about 20 percent. The FDA also delayed a new food traceability rule last year, which would have required records meant to help investigators find and remove contaminated food more quickly.
Why are former FDA officials criticizing the response?
Kennedy said last week that the Cyclospora surge was “under control,” but former food-safety officials and public health critics disputed that assessment. Brad Woodhouse, president of Protect Our Care, said in a statement that past Trump administration assurances about crises should make the public wary.
Frank Yiannas, who served as FDA deputy commissioner for food policy and response during the first Trump administration and under President Biden, told Politico the outbreak was approaching a “catastrophic” level because of what he described as mismanagement. Yiannas pointed to the size of the outbreak, consumer confusion, mixed public messaging and what he called a lack of strong federal leadership. He has called for an independent investigation into the federal response.
Susan Mayne, who led the FDA’s Center for Food Safety and Applied Nutrition from 2015 to 2023, wrote in Stat that the outbreak shows nutrition policy and food safety cannot be treated as separate projects. She said consumers should not have to choose between eating fruits and vegetables and trusting that those foods are safe.
For shoppers, the confirmed picture remains narrow: the FDA has linked the largest known outbreak to Taylor Farms iceberg lettuce sold through Taco Bell and other companies, while five other outbreaks still lack an identified source. That uncertainty is exactly why traceability, staffing and clear public warnings matter when the contaminated product is perishable and may already be gone by the time investigators catch up.
