Michigan's Department of Health and Human Services confirmed Monday that two residents who contracted cyclosporiasis have died. Both individuals had "significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration," according to state medical records.
The announcement comes as Michigan reports 11,234 cases of the parasitic infection, which causes severe watery diarrhea, appetite loss, weight loss, and other gastrointestinal distress, per the Centers for Disease Control and Prevention (CDC). As of Thursday, 193 people in the state have required hospitalization.
The CDC, the Food and Drug Administration (FDA), and state health agencies are investigating multiple outbreaks. One has been traced to iceberg lettuce from central Mexico, distributed by Taylor Farms, which issued a voluntary recall on July 17. That recall covers all lettuce grown in the region.
This outbreak is part of a broader national surge. The CDC reports that 45 states have documented cases, with 6,707 laboratory-confirmed infections as of last Tuesday. Additionally, more than 11,500 suspected cases are pending further analysis or have not been lab-confirmed.
Federal health officials acknowledged the Michigan fatalities and are updating their public tracking to include death counts alongside case and hospitalization figures. The CDC urges consumers to avoid recalled lettuce, thoroughly wash produce and surfaces with hot, soapy water or a dishwasher, and seek medical attention if symptoms develop—typically appearing about a week after exposure.
While Michigan health authorities stress that cyclosporiasis is "generally not a life-threatening illness" and deaths are "uncommon" in the U.S., the fatalities underscore the severity for vulnerable populations. The state's large case count has drawn political attention, with primary races highlighting public health responses and resource allocation.
The FDA is also investigating a separate cyclospora outbreak that has sickened 93 people, indicating the pathogen's persistence. As officials work to contain the spread, the situation in Michigan could influence statewide political dynamics ahead of the midterms.
Public health experts emphasize that immunocompromised individuals and the elderly face higher risks of severe dehydration and complications. The CDC continues to coordinate with state and federal partners to identify contaminated sources and prevent further infections.
