Michigan health officials have confirmed the first two deaths associated with an ongoing outbreak of cyclosporiasis, a parasitic infection commonly spread through contaminated food or water that can cause severe diarrhea. Both individuals had "significant underlying health conditions that may have been impacted by cyclosporiasis and dehydration," according to state health authorities.
The foodborne illness has reached 45 states, with the U.S. Centers for Disease Control and Prevention (CDC) reporting nearly 7,000 laboratory-confirmed cases nationwide. While deaths from cyclosporiasis are uncommon and the illness is "not usually life-threatening," health officials noted.
Michigan is considered the epicenter of the current outbreak, with its records indicating over 11,000 cases and 193 hospitalizations, though not all have been laboratory-confirmed. The parasite, which thrives in warm conditions, infects the intestines and is transmitted through fecal contamination. Past outbreaks have been linked to fruits and vegetables irrigated with contaminated water.
Officials have identified lettuce imported from Taylor Farms in Mexico as a likely source for this year's widespread outbreak. The company, a significant supplier to U.S. food establishments, has initiated a voluntary recall of lettuce sourced from central Mexico. Fast-food chain Taco Bell has also removed lettuce from this supplier from its menu.
The CDC advises consumers to wash all produce under running water, even if labeled as pre-washed. For fruits and vegetables, cooking them to an internal temperature of at least 70°C (158°F) can kill the parasite.
