Explosive Cyclospora outbreak leaves Michigan approaching 1,000 cases
Key Points:
- Reported cases of cyclosporiasis, caused by the Cyclospora parasite, are rising sharply in the U.S., with Michigan alone confirming nearly 1,000 cases as of July 8, a significant increase from the national baseline of 145 cases earlier in the season.
- The infection leads to severe gastrointestinal symptoms such as watery diarrhea, stomach cramps, bloating, and increased gas, affecting over a dozen states so far.
- Cyclospora outbreaks in the U.S. are typically linked to imported fresh produce like basil, cilantro, mesclun lettuce, raspberries, and snow peas, although none of the recent patients reported international travel.
- Health authorities, including the Michigan Department of Health and Human Services, are conducting traceback investigations and advising food handlers to thoroughly wash or cook fresh produce to prevent further spread.
- Restaurants and commercial kitchens in Southeast Michigan are urged to use whole produce instead of pre-washed bagged mixes and to follow strict hygiene practices to control the outbreak.
