TL;DR
West Virginia has confirmed a cyclosporiasis outbreak affecting dozens of residents. Health officials are investigating contaminated produce as the source. The situation remains under review.
West Virginia health authorities have confirmed a cyclosporiasis outbreak affecting at least 50 residents, with cases linked to contaminated produce. The outbreak has prompted an investigation into local food sources, and health officials warn residents to exercise caution with raw vegetables and salads.
According to the West Virginia Department of Health and Human Resources, 50 confirmed cases of cyclosporiasis have been reported across multiple counties since early April 2024. The outbreak was identified after patients presented symptoms such as severe diarrhea, stomach cramps, and nausea, which are consistent with the parasitic infection.
Health officials have traced the cases to a common source: fresh produce, including leafy greens and pre-packaged salads, distributed through local grocery stores. The investigation is ongoing, but authorities have advised residents to avoid consuming raw vegetables from certain suppliers until further notice.
The Centers for Disease Control and Prevention (CDC) has been notified and is assisting in the investigation, which aims to determine whether a specific farm, distributor, or supply chain is responsible for the contamination.
Implications for Public Health and Food Safety
This outbreak highlights the ongoing risks associated with fresh produce and parasitic infections. Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which can lead to prolonged gastrointestinal illness. The incident underscores the importance of food safety measures and prompt investigation to prevent further cases and protect public health.
While no deaths have been reported, dozens of residents have experienced significant illness, and health officials emphasize the need for increased vigilance in food handling and hygiene practices.

Background on Cyclosporiasis and Previous Outbreaks
Cyclosporiasis is a diarrheal illness caused by the Cyclospora cayetanensis parasite, which is often linked to contaminated fresh produce. Outbreaks have occurred in the U.S. periodically, frequently associated with imported or improperly handled vegetables and salads.
In recent years, the CDC has documented multiple outbreaks tied to imported berries, leafy greens, and herbs. The parasite’s lifecycle requires specific environmental conditions, making contamination and outbreaks challenging to control. The current West Virginia outbreak is part of this pattern, with investigations focusing on the supply chain.
“We are actively investigating the source of this outbreak and advise residents to avoid raw produce from certain suppliers until further notice.”
