Lettuce at Taco Bell in 5 states confirmed as a source of diarrhea-causing parasite

Federal health officials identified lettuce from Taco Bell in five U.S. states as the source of a cyclospora parasite outbreak. The CDC and FDA confirmed the contaminated shredded iceberg lettuce was supplied by Taylor Farms, prompting Taco Bell to switch suppliers. Over 30 states reported cyclospora cases, though not all may be linked to the same source.
