Michigan leads U.S. cyclosporiasis outbreak as cases exceed 3,000
U.S. health officials are tracking a multi‑state outbreak of cyclosporiasis, a foodborne intestinal parasite, that has sickened more than 3,000 people. Michigan bears the brunt, reporting over 3,300 confirmed cases and 44 hospitalizations, while Ohio has logged 361 cases and 46 hospitalizations. The CDC has confirmed 843 cases across 31 states, but the true number is expected to rise because of reporting delays. Early investigations point to lettuce or other salad greens as a possible source, but no specific grower, supplier, or product has been identified. The outbreak has prompted the FDA to note a “signal” toward lettuce and to advise consumers to avoid pre‑washed bagged salads, favor whole heads of lettuce, discard outer leaves, and wash produce thoroughly, though washing alone may not eliminate the parasite. Hospitals report no deaths, but severe dehydration remains a concern, especially for children, older adults, and immunocompromised patients. Federal agencies, including the CDC and FDA, are using genetic sequencing and supply‑chain tracing to locate the contamination, while budget cuts to surveillance programs have hampered rapid detection. The uncertainty has affected the food service sector; Taco Bell temporarily removed certain ingredients as a precaution, and Yum Brands’ shares fell after media reports linked the outbreak to its restaurants. Public health messages stress hand hygiene, proper produce handling, and seeking medical care for prolonged watery diarrhea.
