A Cyclospora outbreak linked to produce from central Mexico has prompted changes in American eating habits, according to a CBS News/YouGov poll. The survey found that four in 10 U.S. adults are buying or eating less produce due to concerns over the parasite. Women and older adults are more likely to reduce consumption than men and younger people. The outbreak has garnered significant attention, with nearly as many Americans following the news as those tracking the conflict with Iran.
Former FDA Commissioner Dr. Scott Gottlieb suggested the outbreak is not yet fully under control, though the FDA has identified central Mexico as the likely source. He noted that the parasite thrives in human fecal matter, suggesting contamination from sewage on growing fields. Mexican authorities have denied responsibility. Gottlieb recommended buying whole heads of lettuce rather than pre-chopped bags and purchasing locally grown produce to reduce risk.
The poll also revealed mixed confidence in the FDA's handling of the outbreak. While more respondents expressed confidence than not, few reported having "a lot" of confidence in the agency. Political affiliation influenced perceptions, with more Republicans expressing confidence than Democrats. The survey was conducted with 2,193 U.S. adults between July 22-24, 2026, with a margin of error of ±2.7 points.
