Public health officials across the country are currently monitoring a widespread outbreak of cyclosporiasis, a gastrointestinal illness triggered by the Cyclospora parasite. With confirmed cases rising in at least 31 states, residents are being urged to stay informed about food safety practices to protect their health this season.
As of July 10, 2026, the CDC has confirmed 843 cases domestically, though the actual number is likely much higher due to thousands of suspected cases currently under review. While we track these national trends, it is essential to remain vigilant about the food we consume and how we prepare it at home.

Understanding the Current Outbreak
The scale of this outbreak is significant, with Michigan reporting over 1,500 cases and dozens of hospitalizations. While no deaths have been linked to the parasite, the nature of the illness requires serious attention from both medical professionals and the public.
Transmission and Symptoms
It is important to understand that cyclosporiasis is not transmitted person-to-person, but rather through the ingestion of food or water contaminated with feces. Symptoms often include severe watery diarrhea, loss of appetite, and weight loss, which can unfortunately persist for weeks if left untreated.

Essential Safety Tips for Produce
