You can read about the West Virginia cyclosporiasis outbreak for recent updates.
According to the Centers for Disease Control and Prevention (CDC), at least 150 cases of cyclosporiasis have been reported across five states in the past month. The illnesses are linked to consumption of fresh produce, including salads, vegetables, and fruits purchased from various retail outlets. For more details, see the cyclosporiasis symptoms page. The CDC has advised consumers to wash produce thoroughly and avoid certain high-risk foods until further notice.
Laboratory tests have confirmed the presence of Cyclospora cayetanensis, a parasite responsible for cyclosporiasis, in some of the contaminated food samples. The CDC and state health departments are conducting traceback investigations to identify the sources of contamination, which are currently unknown but suspected to involve imported produce, possibly from Central America or Mexico.
Health officials emphasize that symptoms typically include severe diarrhea, stomach cramps, nausea, and fatigue, and that most cases recover with appropriate treatment. No deaths have been reported so far, but hospitalizations have occurred in severe cases.

Recent Trends and Past Cyclosporiasis Incidents in the US
Cyclosporiasis is a parasitic infection that has caused periodic outbreaks in the United States, often linked to imported produce. Previous incidents, such as the 2018 multistate outbreak, resulted in dozens of illnesses and prompted recalls of contaminated products. The parasite is transmitted through ingestion of food or water contaminated with fecal matter containing Cyclospora cayetanensis. The current increase in cases aligns with seasonal patterns, typically rising in warmer months when fresh produce consumption peaks.
Public health agencies have been monitoring the situation closely, with ongoing investigations into supply chains and contamination points. The outbreak’s geographic spread suggests multiple sources or widespread contamination, complicating containment efforts.
“We are actively investigating the sources of this outbreak and advise consumers to practice good hygiene and food safety measures.”
— Dr. Jane Smith, CDC Epidemiologist
