CHARLESTON, W.Va. — The West Virginia Department of Health’s Bureau for Public Health is urging residents to take precautions as the state investigates a multi‑state outbreak of cyclosporiasis, an intestinal illness caused by the parasite Cyclospora cayetanensis.
As of July 17, officials have confirmed 139 cases linked to the outbreak, including 15 hospitalizations, with infections reported across 26 counties. The Bureau for Public Health is working with the CDC and FDA to identify the source of contamination.
State health officials warn consumers to avoid shredded iceberg lettuce served at Taco Bell locations in West Virginia while the investigation continues. Anyone who develops symptoms — including watery diarrhea, stomach cramps, nausea, fatigue, and loss of appetite — should contact a healthcare provider, especially if they consumed shredded iceberg lettuce from Taco Bell within the previous two weeks.
Residents are also advised to thoroughly clean and sanitize surfaces or containers that may have come into contact with the lettuce. Symptoms typically begin about a week after exposure and can last for several weeks without treatment.
The investigation remains ongoing, and public health officials say they will continue working to prevent additional illnesses. Those experiencing sudden or persistent gastrointestinal symptoms are encouraged to seek testing and care.
