Federal health officials identified iceberg lettuce from Mexico served at Taco Bell locations in five states as a source of widespread infections from the diarrhea-causing parasite cyclospora. A U.S. Food and Drug Administration investigation identified a single supplier as the source of the suspect lettuce.
