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

Federal health officials have identified lettuce from Mexico served at Taco Bell locations across five U.S. states as the source of a widespread outbreak. The contaminated lettuce is linked to the parasite cyclospora, which causes diarrhea in affected individuals. This confirmation follows investigations into the food chain's supply. Meanwhile, Taco Bell previously saw a rise in sales following the introduction of its Doritos Locos Tacos, which generated significant interest among various food critics.
