Outbreak Overview
A parasite-driven stomach illness, cyclosporiasis, has spread across the United States this summer. Reported cases exceed 16,000, with more than 300 hospitalizations. Infections cause severe dehydration and explosive diarrhea, though fatalities are rare. Federal and state health officials continue to investigate the source, with some cases linked to contaminated iceberg lettuce, parsley and cilantro.
Contributing Factors
Experts point to several intersecting trends that could fuel future food-borne outbreaks. Changing American diets have increased consumption of raw or minimally processed produce, creating greater exposure to pathogens that hide in the ridges of lettuce and other vegetables. Climate change is warming oceans, encouraging Vibrio bacteria in shellfish and potentially expanding the range of other parasites. Additionally, recent modifications to FoodNet—the CDC’s long-standing surveillance system—made reporting of cyclospora, Listeria, Shigella, Vibrio and Yersinia optional, prompting concerns that the nation’s ability to gauge outbreak magnitude is diminishing.
Official Statements & Responses

Criticism & Opposition
German Rios, senior director of food safety and quality at Fresh Express, warned that the peak of cyclosporiasis outbreaks may not yet have been reached. Kelsey Holloman of the Virginia Department of Health noted that rising ocean temperatures enable Vibrio to thrive, suggesting future case increases.
