Health officials have confirmed an increase in cases of cyclosporiasis across several U.S. states, linked to contaminated fresh produce, prompting public health alerts. The outbreak underscores ongoing concerns about food safety and parasite transmission.
According to the Centers for Disease Control and Prevention (CDC), there have been more than 200 confirmed cases of cyclosporiasis reported in the past month across at least five states, including Indiana, Ohio, and Illinois. The cases are linked to consumption of contaminated leafy greens and berries, which have tested positive for the parasite Cyclospora cayetanensis.
Health authorities have identified several common sources, including pre-packaged salads and fresh berries sold at grocery stores. The CDC has issued food safety advisories urging consumers to wash produce thoroughly and avoid eating raw vegetables and fruits from suspect sources.

Recent Trends and Past Cyclosporiasis Incidents in the U.S.
Cyclosporiasis is a parasitic infection that has caused multiple outbreaks in the U.S. over the past decade, often linked to imported produce. The CDC reports that outbreaks tend to peak during warmer months when fresh produce consumption increases. Previous incidents include a 2018 multistate outbreak linked to bagged salad greens, which resulted in over 1,000 cases. The parasite is transmitted via contaminated food or water, with no person-to-person spread documented.
“We are actively investigating the sources of this outbreak and advise consumers to wash all produce thoroughly and stay informed about recalls.”
