Detroit, MI, July 24, 2026 — Michigan is experiencing a significant outbreak of cyclosporiasis, with state health officials confirming over 8,000 cases since June 22. As of July 23, 160 individuals have been hospitalized due to the illness. The scope of the outbreak extends beyond Michigan, as it has been identified in 34 other states across the country.
The exact source of the cyclosporiasis outbreak has not been definitively identified, but health authorities suspect a link to fresh produce, potentially including items such as lettuce or salad greens. Cyclosporiasis is an intestinal illness caused by the parasite Cyclospora cayetanensis. Symptoms typically include watery diarrhea, loss of appetite and weight, cramping, bloating and gas, nausea, and fatigue. Some people may also experience vomiting, fever, and body aches.
In response to the growing number of cases, health authorities are providing guidance to residents on essential food safety precautions for handling and consuming produce. These recommendations are aimed at minimizing the risk of further transmission and illness. The specific details of the recommended precautions were not provided in the summary.
The Centers for Disease Control and Prevention (CDC) is involved in monitoring the multi-state outbreak. Further information regarding the investigation into the produce source and specific recommendations is expected as the situation develops.
