Overview
- Public health agencies have recorded 1,645 confirmed Cyclospora infections and are investigating more than 5,100 suspected domestic cases, with Michigan reporting the largest cluster.
- Michigan officials say leafy salad mixes are a frequently reported common item in patient interviews, but investigators have not confirmed any single food, farm, or supplier as the source.
- The CDC and FDA are conducting interviews and complex multi-state supply‑chain tracing while warning that multiple contaminated sources remain possible and that the parasite’s slow maturation complicates recall.
- Taco Bell voluntarily removed several fresh ingredients from selected outlets, such as lettuce and cilantro, as a precaution, and the company says no link has been confirmed by health authorities.
- Cyclospora causes prolonged watery diarrhea that can require antibiotics and hospitalization, so officials urge testing for persistent symptoms and caution with raw produce while investigations continue.
