Federal health investigators have identified lettuce from Mexico served at Taco Bell as a source in a widespread Cyclospora outbreak, according to the CDC. The parasite has caused illness characterized by diarrhea and stomach pain affecting multiple consumers.
The CDC has determined that shredded iceberg lettuce sold in grocery stores or served at other restaurants is not affected by the outbreak, suggesting the contamination was specific to lettuce supplied to Taco Bell locations. Authorities are working to identify all individuals who may have been exposed through affected restaurants.
Arizona health officials are actively monitoring cases of the illness within the state as investigators continue to trace the source and scope of the outbreak linked to the imported produce.
