State health officials in Michigan have confirmed the first two deaths linked to an unprecedented outbreak of cyclosporiasis, a foodborne parasitic illness that has now sickened more than 11,000 people across the state.

The Michigan Department of Health and Human Services (MDHHS) announced Monday that both individuals suffered from “significant underlying health conditions” that may have been exacerbated by the intestinal infection and severe dehydration. Authorities declined to release additional personal details regarding the victims.

Surge in Hospitalizations and Cases

The milestone comes as Michigan’s caseload reached 11,234 confirmed and suspected infections, with at least 193 patients requiring hospitalization. Health officials noted that while cyclosporiasis is rarely life-threatening in the United States, severe cases can lead to prolonged gastrointestinal distress and dehydration, particularly among vulnerable or immunocompromised individuals.

Nationally, the Centers for Disease Control and Prevention (CDC) has tracked thousands of additional cases across dozens of states. Federal investigators have focused surveillance on fresh produce—specifically imported iceberg lettuce and pre-packaged salad greens—as a potential vector for the microscopic parasite, Cyclospora cayetanensis.

Public Health Recommendations

Cyclosporiasis infects the small intestine and typically causes watery diarrhea, stomach cramps, nausea, and fatigue. Symptoms usually appear within one to two weeks following exposure to contaminated food or water.

Health agencies are advising residents to thoroughly wash all fresh produce under running water, peel raw fruits and vegetables when possible, or cook produce to at least 158°F (70°C) to kill the parasite. Anyone experiencing persistent gastrointestinal symptoms is urged to consult a healthcare provider for diagnosis and targeted antibiotic treatment.
