TL;DR
West Virginia health authorities have confirmed a cyclosporiasis outbreak affecting multiple counties. The source is under investigation, and officials warn residents to exercise caution with fresh produce.
West Virginia health officials have confirmed a cyclosporiasis outbreak affecting residents across several counties, marking the first significant cluster in the state this year. The outbreak is linked to contaminated produce, prompting warnings and ongoing investigations by public health authorities. This development matters because cyclosporiasis can cause severe gastrointestinal illness, especially in vulnerable populations, and highlights concerns about food safety in the region.
According to the West Virginia Department of Health and Human Resources, at least 25 cases of cyclosporiasis have been confirmed since early April, with reports coming from counties including Kanawha, Berkeley, and Jefferson. The cases involve individuals experiencing symptoms such as diarrhea, stomach cramps, and nausea, consistent with cyclosporiasis caused by the parasite Cyclospora cayetanensis.
Health officials have stated that preliminary investigations suggest the outbreak is linked to fresh produce, possibly contaminated lettuce or berries, though no definitive source has yet been identified. The Centers for Disease Control and Prevention (CDC) is assisting local agencies with epidemiological studies and testing.
Residents are advised to practice good hygiene, wash all produce thoroughly, and avoid consuming unwashed or raw vegetables and fruits until the source is identified and contained. No deaths have been reported, but several patients have required medical treatment, including antibiotics and hydration therapy.
Why the West Virginia Cyclosporiasis Outbreak Is Concerning
This outbreak underscores the ongoing risks associated with fresh produce and food safety, especially as cyclosporiasis outbreaks have been linked to contaminated imported and domestic produce in recent years. It raises awareness about the importance of proper food handling and hygiene practices to prevent illness. For residents, the outbreak presents a direct health risk and highlights the need for vigilance when consuming raw fruits and vegetables. Public health authorities emphasize that early detection and prompt treatment are essential to managing the illness and preventing further spread.

Recent Cyclosporiasis Cases and Food Safety Concerns in the US
Cyclosporiasis, caused by the parasite Cyclospora cayetanensis, has been responsible for multiple outbreaks across the US over the past decade, often linked to contaminated produce imported from countries with less stringent food safety controls. In 2023, several outbreaks were traced to imported berries and leafy greens, prompting increased scrutiny of supply chains. West Virginia’s current outbreak is part of this broader pattern, though local investigations are still underway to identify specific sources.
Historically, outbreaks tend to occur in warmer months when fresh produce consumption peaks. The CDC has issued guidelines for consumers and vendors to reduce risk, including thorough washing and proper refrigeration of produce. The outbreak in West Virginia follows national trends, emphasizing the ongoing challenge of controlling foodborne parasites.
“We are actively investigating the source of this outbreak and are advising residents to exercise caution with raw produce until further notice.”
