Michigan officials have confirmed the first two deaths associated with the multistate cyclospora outbreak that has sickened thousands of people across the United States, state health authorities said.
What officials are reporting
State officials said the two people who died had “significant underlying health conditions” that may have been worsened by cyclosporiasis and resulting dehydration. The Michigan Department of Health did not release further identifying details about the individuals.
“It is not usually life-threatening,”
The U.S. Centers for Disease Control and Prevention has emphasized that deaths from cyclosporiasis are rare, while warning that severe symptoms can occur, particularly in vulnerable people.
Scope of the outbreak
Federal and state health data put the outbreak’s scale in stark relief:
- 45 states have reported cases linked to the current wave.
- There are nearly 7,000 laboratory-confirmed infections nationwide, according to the CDC.
- Michigan, which health officials describe as at the epicenter, has recorded more than 11,000 reported cases and 193 hospitalizations, though many of those Michigan reports have not been laboratory-confirmed.
Public health investigators say Cyclospora cayetanensis — a microscopic parasite that infects the intestines — is typically spread through food or water contaminated with fecal material. The parasite thrives in warm conditions and has been implicated in past outbreaks linked to fresh produce.
| Measure | Reported figure |
|---|---|
| States with cases | 45 |
| Lab-confirmed U.S. cases | Nearly 7,000 |
| Michigan reported cases | More than 11,000 |
| Michigan hospitalizations | 193 |
Links to food supply and responses
Investigators have connected this outbreak to lettuce imported from central Mexico and supplied by Taylor Farms, a vendor for many U.S. foodservice operations. In response:
- Taylor Farms announced a voluntary recall covering lettuce sourced from central Mexico.
- Fast-food chain Taco Bell said it has removed the supplier’s lettuce from its menu.
- U.K. health authorities issued advisories after cases were detected in returning travelers.
Health agencies stress that routine washing may not fully remove Cyclospora from fresh produce. The CDC notes that cooking produce to at least 70°C (158°F) will kill the parasite. For raw produce, the agency advises washing under running water, including items labeled pre-washed, while acknowledging limitations of that measure.
What this means for the public
Most infected people experience watery diarrhea, fatigue and abdominal discomfort; dehydration can follow, particularly among older adults or those with chronic health conditions. Public health officials urge clinicians to consider cyclosporiasis when patients present with prolonged gastrointestinal symptoms and to report suspected cases promptly to aid outbreak control.
The situation remains under active investigation by federal and state health agencies. Officials say they are working to trace contaminated batches, notify affected distributors and advise the public on precautions to limit further spread.
Key takeaways: the outbreak has reached a broad geographic footprint, has been linked to a specific supplier and imported lettuce, and has resulted in the first confirmed deaths in Michigan among people with significant underlying conditions — underscoring the danger the parasite poses to vulnerable patients even though fatalities are uncommon.
