Cyclospora Cases Rise: Are Local Cases Linked to National Outbreak?

As of July 16, 2026, Shelby County has recorded six cases of cyclosporiasis, a parasitic illness known for causing severe diarrhea. The Shelby County Health Department has indicated that four of these reported cases are linked to travel and are not part of the current national outbreak.

The remaining two local cases are still under investigation by health authorities. It remains unclear if any of these cases have emerged since the recent national outbreak began. The U.S. is experiencing a significant rise in cyclosporiasis, with over 4,000 cases reported nationwide by July 13, 2026.

This parasitic illness is commonly transmitted through contaminated fresh fruits, vegetables, and herbs. Commonly implicated foods include bagged salad mixes, cilantro, basil, raspberries, and green onions. Public health guidance has primarily focused on safe produce preparation at home, with less information available for dining out risks.
