Federal officials worked with Michigan investigators to trace a Cyclospora outbreak to iceberg lettuce supplied by Taylor Farms to Taco Bell locations. The contaminated lettuce may also have been distributed to other vendors, expanding potential exposure risks.

The investigation identified the specific produce source through coordinated efforts between federal agencies and state health departments. Taylor Farms, a major produce supplier, provided the implicated lettuce to the fast-food chain.

Health authorities continue monitoring for additional cases while assessing the full distribution scope. Consumers who ate at affected locations should watch for symptoms including watery diarrhea, loss of appetite, and fatigue.

The outbreak highlights ongoing challenges in food supply chain traceability and the importance of rapid multi-jurisdictional response to foodborne illness clusters.
