Cyclospora Outbreak: Washing Isn't Enough

As of July 16, 2026, a widespread Cyclospora outbreak has impacted thousands across several states, with cases reported since May 1, 2026. The parasite contaminates fresh produce, leading to symptoms such as prolonged diarrhea, stomach cramps, and fatigue. Unlike bacteria, Cyclospora is difficult to remove from fruits and vegetables, even with thorough washing.

Darin Detwiler, a food safety professor, advises that washing produce offers reduced risk but not complete assurance against Cyclospora. He stresses the importance of layered food safety practices rather than relying on a single action. Consumers are encouraged to choose whole produce items over pre-cut options when possible, as fewer handling steps may reduce exposure risk.

Crucially, Detwiler urges the public to pay close attention to health advisories and warnings. He states that consumers should not assume extra rinsing can safeguard produce identified in recalls or outbreak alerts. If health officials advise against consuming specific foods or brands due to contamination, prompt disposal is recommended.
