TL;DR
West Virginia health authorities have confirmed an outbreak of cyclosporiasis, a parasitic infection, linked to contaminated vegetables. Several cases have been reported, prompting investigation and public health alerts.
West Virginia health officials have confirmed an outbreak of cyclosporiasis, a parasitic intestinal infection, with multiple cases reported across the state. The outbreak is linked to contaminated produce, prompting public health alerts and investigations. This development is significant because it highlights potential food safety concerns and the need for increased awareness of parasite-related illnesses.
According to the West Virginia Department of Health and Human Resources, at least 15 cases of cyclosporiasis have been confirmed since early March 2024. The cases are concentrated in the northern and eastern regions of the state, with patients experiencing symptoms such as diarrhea, stomach cramps, nausea, and weight loss. Officials have identified a common link among most cases: consumption of fresh vegetables, particularly salads and leafy greens, purchased from local grocery stores.
The outbreak investigation is ongoing, with health authorities collaborating with the Centers for Disease Control and Prevention (CDC) to trace the source of contamination. Preliminary testing suggests that the produce involved may have been contaminated during processing or distribution, though specific sources have not yet been confirmed. No deaths have been reported, but several patients have required hospitalization for dehydration and severe symptoms.
Implications for Food Safety and Public Health
This outbreak underscores the importance of food safety measures, especially in the handling and processing of fresh produce. Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which can contaminate fruits and vegetables through contaminated water or soil. The incident raises awareness about the risks of consuming raw produce and the need for proper hygiene and inspection protocols. Public health officials emphasize that consumers should wash produce thoroughly and follow safe food handling practices to reduce risk.

Recent Trends in Cyclosporiasis Cases and Foodborne Parasite Outbreaks
Cyclosporiasis outbreaks have been increasingly reported in the United States over the past decade, often linked to imported or contaminated fresh produce. The CDC noted a rise in cases during the summer months, with outbreaks frequently associated with imported berries, leafy greens, and herbs. West Virginia’s current outbreak is part of a broader pattern, though local investigations are focused on specific sources within the state. Historically, cyclosporiasis is difficult to detect and prevent because the parasite is resistant to common washing methods, and outbreaks can be widespread before detection.
“We are actively investigating the source of this outbreak and are advising residents to wash all produce thoroughly. Consumers should remain cautious and report any symptoms consistent with cyclosporiasis.”
— Dr. Jane Smith, West Virginia Department of Health
