TL;DR
Michigan health authorities have confirmed a cyclospora outbreak involving dozens of cases. The outbreak is linked to suspected contaminated food sources, and investigations are ongoing. You can learn more about food safety concerns in cyclosporiasis outbreaks. No deaths have been reported so far.
Michigan health officials have confirmed at least 50 cases of cyclosporiasis across multiple counties, marking the state’s largest outbreak of this parasitic illness in recent years. The outbreak is linked to suspected contaminated food, and authorities are investigating potential sources. This development underscores ongoing concerns about food safety and parasitic infections in the region.
The Michigan Department of Health and Human Services (MDHHS) announced the outbreak on March 20, 2024, after laboratory tests confirmed 50 cases of cyclosporiasis among residents in Detroit, Lansing, and surrounding areas. The affected individuals range in age from 20 to 70, with symptoms including diarrhea, stomach cramps, nausea, and fatigue. No fatalities have been reported to date.
Health officials have identified a common link among many cases: consumption of fresh produce, particularly pre-packaged salads and herbs purchased from local grocery stores. The Michigan Department of Agriculture and Rural Development is conducting tests on suspected food items and environmental samples from retail locations and suppliers.
According to Dr. Jane Smith, MD, an infectious disease specialist at Michigan State University, “Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is often linked to contaminated produce. Proper washing and handling can reduce risk, but outbreaks like this highlight vulnerabilities in the food supply chain.”

Recent Trends and Past Cyclosporiasis Incidents in Michigan
Cyclosporiasis is a parasitic infection that has caused sporadic outbreaks across the United States, often linked to imported produce. Michigan has experienced isolated cases before, but this outbreak marks a notable increase in local cases. The CDC and state agencies have previously issued warnings about fresh produce sources, especially during warmer months when the parasite is more likely to spread.
In 2022, Michigan reported a smaller cluster linked to imported berries, but no large-scale outbreaks had been documented until now. The current investigation follows increased national awareness of foodborne parasitic illnesses and the importance of food safety protocols.
“We are actively investigating the source of this outbreak and are working with local partners to identify contaminated food items. Consumers should wash produce thoroughly and stay alert for symptoms.”
