Michigan cyclosporiasis outbreak possibly linked to lettuce or salad greens

A state health department has identified a widespread outbreak of a parasitic illness that is causing severe, “explosive” diarrhea among residents. Early investigations point to contaminated lettuce or salad greens as the likely source, with confirmed cases reported in several counties across the state. The outbreak has prompted the department to issue a public health alert and to work with local food distributors and grocery chains to trace the supply chain and identify the specific contamination point.

Officials say the parasite, which can be transmitted through ingestion of contaminated produce, has been linked to a handful of outbreaks nationwide in recent years. The current investigation is focused on pinpointing the exact variety of greens and the distribution network involved, as well as determining whether the contamination occurred at the farm, during processing, or at a distribution center. Health authorities are urging anyone who has consumed lettuce or salad greens from local markets in the past month to monitor for symptoms and seek medical care if they develop sudden, severe diarrhea.

The state’s Department of Health has intensified surveillance and is coordinating with the Centers for Disease Control and Prevention to monitor the situation. While the investigation continues, consumers are advised to wash produce thoroughly, consider cooking greens when possible, and stay alert for any gastrointestinal symptoms. The department will provide updates as more information becomes available.
