Cyclosporiasis cases in Buncombe County, North Carolina, have surged, with health officials linking a spike in severe diarrheal illness to contaminated salad ingredients. The CDC reports at least 45 confirmed infections as of mid-July 2026.
The parasite Cyclospora cayetanensis triggers watery diarrhea, fatigue, and cramps. Untreated, symptoms can persist for weeks. Local health departments urge immediate reporting of any suspected cases to track the outbreak source.
High-risk produce includes bagged salads, cilantro, basil, raspberries, and snow peas. CNN and Vox reports confirm these items, often imported from regions with poor sanitation, are the primary vectors. The Vox piece emphasizes: “Don’t give up vegetables because of the diarrhea parasite.” Not all greens are dangerous. Cooked vegetables, peeled fruits, and thoroughly washed produce heated to at least 145°F kill the organism.
What is safe to eat? Focus on local, traceable produce, advises the Press Herald. A quick reference:
| Avoid | Safe |
|---|---|
| Bagged salad mixes | Cooked broccoli, spinach |
| Fresh cilantro, basil | Peeled apples, bananas |
| Raspberries, snow peas | Thoroughly washed, heated produce |
Prevention requires rigorous washing. Scrub produce under running water. Soak in a vinegar solution (1 part vinegar to 3 parts water) for 15 minutes. Avoid cross-contamination in kitchens. Restaurants must cook all potentially contaminated items above 145°F.
If you suspect infection: persistent diarrhea, dehydration, or blood in stool signals need for medical help. Antibiotics like trimethoprim-sulfamethoxazole (TMP-SMX) are effective if diagnosed early. Report cases to local health authorities to aid tracking.
The Buncombe County outbreak exposes systemic failures in produce safety. Global supply chains lack routine testing for Cyclospora. Policy changes and consumer vigilance are needed. Support local farms. Demand better food safety regulations.
