Cyclospora Outbreak Raises Food Safety Concerns Across the U.S.

Health officials across the United States are tracking a rise in Cyclospora cayetanensis infections, a parasitic illness that spreads through contaminated food and water. The CDC reports dozens of confirmed cases annually, with periodic outbreaks tied to fresh produce like cilantro, basil, raspberries, and pre-packaged salad mixes. Symptoms include prolonged watery diarrhea, fatigue, nausea, and stomach cramps that can last weeks without treatment. The parasite thrives in tropical and subtropical regions, and imported produce carries the highest transmission risk during warmer months.

Black disadvantaged communities at higher risk The 2026 season continues a troubling pattern of Cyclospora cases linked to restaurant meals and grocery store produce. Investigators with the CDC and FDA trace most U.S. clusters to fresh herbs and leafy greens imported from Mexico and Central America. Black communities face compounded exposure risk through food service work, where fresh herbs appear frequently in cultural cooking and in high-volume restaurant kitchens with limited food safety oversight.

Ways to lower risk of Infection

Cooking produce to proper temperatures kills Cyclospora entirely, making heat the strongest line of defense for high-risk items like fresh herbs. Anyone experiencing symptoms lasting more than a few days should contact a doctor immediately, since a simple antibiotic course of trimethoprim-sulfamethoxazole clears the infection quickly when caught early.

Staying informed

Staying informed through CDC and local health department alerts gives you a real-time advantage during active outbreaks. The CDC's food safety page publishes ongoing outbreak investigations with specific product recalls and retailer information. Checking those updates regularly, especially during summer months when cases spike, keeps you a step ahead of contaminated product hitting store shelves.
