West Virginia health officials have confirmed an outbreak of cyclosporiasis, a parasitic intestinal illness, linked to contaminated produce. The outbreak has resulted in multiple confirmed cases across the state, prompting public health warnings and investigations. The Centers for Disease Control and Prevention (CDC) is assisting local authorities in tracing the source of contamination and preventing further cases.
According to the West Virginia Department of Health and Human Resources, at least 25 cases of cyclosporiasis have been confirmed since early April 2024. The affected individuals reported symptoms such as severe diarrhea, stomach cramps, nausea, and weight loss, typical of the infection caused by the parasite Cyclospora cayetanensis. The source of the outbreak appears to be contaminated fresh produce, with preliminary investigations pointing toward imported leafy greens or berries, though no definitive source has yet been identified.The CDC has issued a health alert, urging consumers to wash all fresh produce thoroughly and avoid raw vegetables from suspicious sources. Local health departments are working with food distributors and retailers to identify contaminated batches and remove them from the supply chain. No fatalities have been reported, but several patients have required medical treatment, including hydration therapy in severe cases.
Public Health Impact of the West Virginia Cyclosporiasis Outbreak
This outbreak highlights the ongoing risks associated with contaminated fresh produce and underscores the importance of food safety practices. Cyclosporiasis is a potentially serious illness, especially for vulnerable populations such as the elderly and immunocompromised. The investigation’s findings could lead to stricter import and handling regulations for produce, and raise awareness about foodborne parasitic infections. For consumers, it emphasizes the need for thorough washing and cautious sourcing of raw vegetables.

Previous Cyclosporiasis Incidents and Food Safety Measures
Cyclosporiasis outbreaks have occurred periodically across the US, often linked to imported produce such as berries and leafy greens. The parasite Cyclospora cayetanensis is resistant to standard washing, making contamination difficult to detect. The CDC has previously issued alerts during similar outbreaks, which often trace back to contaminated food sources from Latin America, particularly Mexico and Central America. The current outbreak in West Virginia follows a pattern seen in past incidents, where imported produce was identified as a common source. Food safety agencies have increased testing and monitoring, but outbreaks still occur due to complex supply chains and contamination points.“We are actively investigating the source of this outbreak and advising residents to thoroughly wash all produce. Our priority is to prevent further cases and ensure food safety.”
