TL;DR
West Virginia has confirmed a cyclosporiasis outbreak affecting dozens of residents. Health authorities are investigating possible contaminated produce sources. The outbreak highlights ongoing food safety concerns.
West Virginia health authorities have confirmed dozens of cases of cyclosporiasis in the state, marking a recent outbreak linked to contaminated produce. The outbreak, which was announced by the West Virginia Department of Health and Human Resources on April 25, 2024, underscores ongoing concerns about foodborne parasitic infections and their impact on public health.
The West Virginia Department of Health and Human Resources (DHHR) reported at least 45 confirmed cases of cyclosporiasis across multiple counties. Patients have reported symptoms including severe diarrhea, stomach cramps, and nausea, consistent with the illness caused by the parasite Cyclospora cayetanensis. No deaths have been reported, but several patients have required hospitalization for dehydration.
Health officials have identified fresh produce as the likely source, though specific items are still under investigation. The DHHR has issued a warning advising residents to avoid consuming unwashed or improperly handled produce, especially leafy greens and berries, which are common sources of the parasite. The Centers for Disease Control and Prevention (CDC) is collaborating with state officials to trace the outbreak’s source and determine if a common supplier is involved.

Recent Trends in Cyclosporiasis and Foodborne Parasite Outbreaks
Cyclosporiasis, caused by the Cyclospora cayetanensis parasite, has been responsible for multiple outbreaks in the U.S. over recent years, often linked to imported produce. Notably, outbreaks have been associated with contaminated berries and leafy greens, prompting recalls and heightened safety protocols. The CDC reports that cyclosporiasis cases tend to increase during warmer months, coinciding with peak produce harvesting seasons. West Virginia’s current outbreak follows similar patterns seen in previous years, raising concerns about supply chain safety and food inspection standards.
“Cyclosporiasis outbreaks are often linked to contaminated produce, and we are working with local health departments to identify the specific source in West Virginia.”
