West Virginia health officials have confirmed dozens of cases of cyclosporiasis, a parasitic infection caused by Cyclospora cayetanensis, linked to contaminated produce. The outbreak underscores ongoing concerns over food safety and prompt public health response.
The West Virginia Department of Health and Human Resources announced that at least 45 residents have tested positive for cyclosporiasis since early June. The infections are believed to be associated with consumption of fresh produce, though the specific source remains under investigation, according to state health officials.
Laboratory testing confirmed the presence of Cyclospora cayetanensis in stool samples from affected individuals, with symptoms including diarrhea, stomach cramps, and nausea. No fatalities have been reported, but several patients required hospitalization for dehydration.
Investigators are currently examining various food sources, with initial focus on leafy greens and pre-packaged salads from multiple local stores. The Food and Drug Administration (FDA) has been notified and is assisting in tracing the contamination source, which is common in produce-related cyclosporiasis outbreaks.

Previous Cyclosporiasis Outbreaks in the US and Produce Safety Concerns
Cyclosporiasis outbreaks have occurred periodically in the United States, often linked to imported or contaminated produce, such as lettuce or berries. Notably, outbreaks in recent years have prompted recalls and increased scrutiny of produce suppliers. The parasite, Cyclospora cayetanensis, is known to thrive in warm, moist environments, making contaminated produce a common vector.
West Virginia has experienced sporadic cases before, but the current outbreak is among the largest reported in the state in recent years. Authorities have emphasized the importance of proper produce handling and washing to reduce infection risks.
“We are actively investigating the source of this outbreak and advise residents to wash all fresh produce thoroughly and stay alert for symptoms.”
— Dr. Susan Miller, West Virginia Department of Health
