LANSING — Michigan health officials have reported the first known deaths linked to the United States' ongoing cyclosporiasis outbreak, saying two people with confirmed infections died after developing complications that included dehydration, marking a significant escalation in the country's largest recorded outbreak of the parasitic illness.
The Michigan Department of Health and Human Services (MDHHS) said the two individuals had significant underlying health conditions that may have been worsened by cyclosporiasis and dehydration. Officials did not release their identities or provide additional details.
The deaths come as Michigan remains the center of a multistate outbreak that has sickened thousands of people. State health officials have reported more than 11,000 outbreak-related cases and nearly 200 hospitalizations, while the U.S. Centers for Disease Control and Prevention has confirmed thousands of laboratory-verified infections nationwide. Investigators continue to examine the full scope of the outbreak and believe many illnesses may not have been formally diagnosed.
Federal and state investigators have linked part of the outbreak to recalled iceberg lettuce supplied by Taylor Farms operations in Mexico and served at Taco Bell locations, although officials have stressed that the recalled product does not account for all reported illnesses. Authorities said the investigation into additional possible food sources remains ongoing.
Cyclosporiasis is caused by the parasite Cyclospora cayetanensis and typically spreads through contaminated food or water. Symptoms commonly include prolonged watery diarrhea, abdominal cramping, nausea and fatigue. While most patients recover with appropriate treatment, severe dehydration can pose serious risks, particularly for older adults and people with underlying medical conditions.
Health officials said the investigation remains active, and additional information will be released as it is confirmed.
