TL;DR
A confirmed outbreak of cyclosporiasis has emerged in Michigan, with over 50 cases reported by health authorities. Investigations are underway to identify the source, but no deaths have been linked so far. For recent updates, see the West Virginia Cyclosporiasis Outbreak report. The outbreak highlights ongoing concerns about foodborne illnesses.
Health officials in Michigan have confirmed more than 50 cases of cyclosporiasis over the past two weeks, marking a significant outbreak of the parasitic intestinal illness. The Michigan Department of Health and Human Services (MDHHS) announced that investigations are ongoing to identify the source, but no deaths have been reported yet. This outbreak underscores the persistent risk of foodborne illnesses and the importance of food safety measures.
The confirmed cases of cyclosporiasis, caused by the parasite Cyclospora cayetanensis, have been reported across multiple counties in Michigan. You can learn more about the cyclospora outbreak in the UK and how it compares. Patients range in age from 20 to 70 years old, with most experiencing symptoms such as diarrhea, stomach cramps, nausea, and fatigue. According to MDHHS spokesperson Sarah Johnson, laboratory tests have confirmed the parasite in stool samples from affected individuals.
Health authorities have not yet identified a definitive source of the outbreak. However, preliminary investigations suggest a possible link to fresh produce, as many patients reported consuming salads or pre-packaged fruits prior to falling ill. The CDC has been notified and is assisting with epidemiological studies to trace the contamination pathway.
While the outbreak is currently contained within Michigan, health officials emphasize the importance of proper food handling and hygiene practices to prevent further spread. No fatalities have been reported, but several patients have required hospitalization for dehydration and severe symptoms.
Implications for Public Health and Food Safety
This outbreak highlights the ongoing risks associated with foodborne parasitic infections in the United States. Cyclosporiasis is often linked to contaminated produce, and outbreaks can affect dozens or even hundreds of people if sources are widespread. The incident underscores the need for strict food safety protocols, increased surveillance, and consumer awareness to prevent future cases. The outbreak also raises questions about supply chain safety and the effectiveness of current inspection systems in detecting parasitic contamination before products reach consumers.

Recent Trends and Past Cyclosporiasis Outbreaks
Cyclosporiasis outbreaks have occurred periodically in the U.S., often linked to imported fresh produce such as berries, leafy greens, and herbs. The CDC reports that in 2022, there were over 300 cases nationwide, mostly traced back to imported vegetables. Previous outbreaks have led to recalls and increased scrutiny of produce suppliers. The parasite Cyclospora cayetanensis is not spread person-to-person but is transmitted through ingestion of contaminated food or water, making food safety measures critical in prevention.
The Michigan outbreak is the latest in a series of seasonal spikes observed in recent years, often coinciding with warmer months when fresh produce consumption increases. Authorities have emphasized that proper washing and handling of produce can reduce risk but may not eliminate the parasite entirely without adequate food safety controls at the source.
“We are actively investigating the source of this outbreak and are advising residents to practice good hygiene and proper food handling. Consumers should wash fresh produce thoroughly and stay alert for symptoms.”
