The CDC reported 86 hospitalizations and no deaths. Sick people ranged in age from 5 to 88 years, with a median age of 44, and 59% were female. The median illness onset date was June 18. Symptoms of cyclosporiasis include diarrhea, cramping, bloating, nausea, fatigue and weight loss.

While cases of cyclosporiasis often climb in the summer, the CDC says multiple states have reported an increase in cases in the last two weeks compared to the same period in 2025. Additionally, the agency says it assumes a six-week reporting lag between illness onset and case reporting, so case counts will likely continue to rise as the agency receives more data.

While the source for this specific outbreak has not been confirmed, cyclosporiasis is often connected to consuming fresh produce such as raspberries, basil, cilantro, lettuce, mesclun mix, snow peas and green onions.

This outbreak follows the CDC’s move in 2025 to reduce the pathogens it monitors under the Foodborne Diseases Active Surveillance Network (FoodNet) from eight to two. The partnership between CDC, the U.S. Department of Agriculture’s Food Safety Inspection Service, the U.S. Food and Drug Administration and 10 state health departments now focuses on salmonella and Shiga toxin-producing E. coli. It previously monitored for cyclospora, as well as campylobacter, listeria, shigella, vibrio and Yersinia.
