West Virginia health officials have confirmed a cyclosporiasis outbreak affecting residents across several counties. The outbreak is linked to contaminated fresh produce, prompting public health warnings and investigations. This is the first confirmed outbreak of its kind in the state this year, highlighting ongoing food safety concerns.
The West Virginia Department of Health and Human Resources (DHHR) announced on March 15, 2024, that at least 25 cases of cyclosporiasis have been confirmed across five counties. The affected individuals reported symptoms including diarrhea, stomach cramps, and fatigue, consistent with the parasitic infection caused by Cyclospora cayetanensis. Officials stated that preliminary investigations suggest contamination from imported produce, though the exact source remains under review.
Public health advisories have been issued urging residents to avoid consuming certain fresh produce items, particularly pre-packaged salads and berries, until further notice. No deaths have been reported, but several patients have required medical treatment. The CDC and local health departments are collaborating to trace the contamination source, which could involve food distribution networks or retail outlets.
Implications for Food Safety and Public Health
This outbreak underscores the ongoing risks associated with imported produce and the importance of food safety protocols. Cyclosporiasis is a parasitic infection that can cause severe gastrointestinal illness, especially in vulnerable populations. The incident highlights the need for stringent inspection and monitoring of fresh produce imports, as well as public awareness about food handling and hygiene.
For residents, the outbreak raises concerns about the safety of the food supply chain and the potential for similar incidents elsewhere. Public health agencies emphasize the importance of early detection and response to prevent wider spread and protect at-risk groups, including immunocompromised individuals and the elderly.

Previous Cyclosporiasis Incidents and Food Safety Measures
Cyclosporiasis outbreaks have occurred periodically in the United States, often linked to imported produce such as berries, lettuce, and herbs. Notably, the CDC reported a significant outbreak in 2022 associated with contaminated basil, prompting increased scrutiny of produce imports and stricter food safety standards. West Virginia has experienced isolated cases before, but this is the first confirmed multi-county outbreak this year.
Federal and state agencies have been working to improve detection and prevention measures, including enhanced inspection protocols and public education campaigns. The outbreak in West Virginia indicates that these efforts need continued reinforcement, especially in light of increasing global food trade.
“We are actively investigating the source of this outbreak and advising residents to avoid certain fresh produce until further notice.”
— Dr. Emily Carter, West Virginia DHHR spokesperson
