West Virginia health officials have confirmed dozens of cases of cyclosporiasis, a parasitic intestinal infection, linked to contaminated vegetables, marking the first confirmed outbreak of this kind in the state this year.
The West Virginia Department of Health and Human Resources announced that at least 50 cases of cyclosporiasis have been identified across multiple counties as of late April 2024. The outbreak is linked to fresh produce, with investigators pointing to leafy greens and other vegetables as potential sources.
Laboratory tests confirmed the presence of Cyclospora cayetanensis, a parasite that causes symptoms such as diarrhea, stomach cramps, and nausea. The health department has issued a public advisory urging consumers to wash produce thoroughly and avoid consumption of unwashed vegetables from local markets.
Officials are currently conducting traceback investigations to identify the specific source of contamination, including testing of food suppliers and farms involved in the distribution chain. No fatalities have been reported, but some patients have required medical treatment.
Implications of the Cyclosporiasis Outbreak in West Virginia
This outbreak highlights the ongoing risk of parasitic infections linked to fresh produce, especially in the context of food safety and supply chain monitoring. It underscores the importance of proper handling and thorough washing of vegetables to prevent illness. For consumers, it raises awareness about the potential health risks associated with raw produce, particularly during warmer months when such infections are more common.
Public health officials emphasize that while the outbreak is contained to a specific region, it serves as a reminder of the need for strict food safety standards and vigilant inspection processes to prevent future incidents. The economic impact on local farmers and markets may also be significant if the source is linked to a specific farm or distributor.

Background on Cyclosporiasis and Past Outbreaks in the US
Cyclosporiasis is caused by the parasite Cyclospora cayetanensis, which is primarily transmitted through contaminated food or water. Outbreaks have been documented in the US over the past decade, often linked to imported produce from regions with less stringent food safety controls.
In recent years, outbreaks have been associated with fresh cilantro, berries, and lettuce, prompting increased surveillance by the CDC and local health agencies. The parasite’s lifecycle requires specific environmental conditions, making contamination of produce during growing, harvesting, or processing a common route of infection.
West Virginia has not previously experienced a significant cyclosporiasis outbreak in recent years, making this event notable as it marks a resurgence of the infection within the state.
“We are actively investigating the source of this outbreak and advising residents to wash all produce thoroughly. We are working closely with suppliers to identify any contamination points.”
— Dr. Lisa Carter, West Virginia Department of Health and Human Resources
