Health officials are warning consumers to take precautions with fresh produce this summer following an outbreak of a diarrhea-causing parasite that has sickened dozens across several U.S. states. The parasite, cyclospora, is typically linked to imported fresh fruits and vegetables, according to the Centers for Disease Control and Prevention.
Outbreak Details and Affected States
As of July 10, 2026, the CDC has reported at least 80 confirmed cases of cyclosporiasis in 12 states, including New York, Texas, and California. The agency is investigating whether the infections are linked to a common food source. No deaths have been reported, but several individuals required hospitalization due to severe dehydration.
Cyclospora causes watery diarrhea, stomach cramps, nausea, and fatigue, which can last for weeks if untreated. The parasite is microscopic and can contaminate produce during growing, harvesting, or processing.
How to Stay Safe
Experts recommend thoroughly washing all fresh produce under running water before consumption, even if it will be peeled. Cooking fruits and vegetables to an internal temperature of at least 145°F (63°C) kills the parasite. Travelers to countries with known cyclospora outbreaks should avoid raw produce from local markets.
"If you are traveling to the U.S. this summer, be cautious about eating raw fruits and vegetables from certain regions," said Dr. Lisa Tran, an infectious disease specialist at Johns Hopkins University. "Stick to cooked or peeled items to reduce risk."
The CDC advises that produce from Mexico, Guatemala, and Peru has been linked to past cyclospora outbreaks. Consumers should check labels and consider buying domestically grown produce when possible.
Treatment and Prevention
Cyclosporiasis is treatable with antibiotics such as trimethoprim-sulfamethoxazole. Anyone experiencing prolonged diarrhea after eating fresh produce should seek medical attention. Public health officials are urging retailers to ensure imported produce meets safety standards.
"We are working with importers to enhance testing and traceability," said a spokesperson for the Food and Drug Administration. "In the meantime, consumers can protect themselves by following proper food handling practices."
