Taco Bell has pulled iceberg lettuce from its restaurants nationwide after federal health officials identified it as a likely source of a cyclosporiasis outbreak affecting consumers across the United States. The lettuce in question was supplied by Taylor Farms and traced to operations in Mexico, according to investigators.

Cyclosporiasis is an intestinal illness caused by the Cyclospora cayetanensis parasite, which can cause prolonged diarrhea, stomach cramps, nausea, and fatigue. The parasite is typically found in contaminated food or water and is not spread from person to person. Health officials are urging anyone who has eaten at Taco Bell recently and is experiencing symptoms to contact a healthcare provider.

The CDC and the Food and Drug Administration are jointly investigating the scope of the outbreak, including the number of confirmed cases and the geographic distribution of illnesses. Taco Bell stated it acted swiftly upon learning of the potential link and has temporarily removed iceberg lettuce from all menu items while the investigation proceeds.

Taylor Farms has not yet issued a formal public recall, though health authorities are monitoring the supplier's distribution chain. Officials noted that the lettuce may have been distributed beyond Taco Bell to other food service customers, though Taco Bell has been identified as the primary point of exposure so far.

Financial analysts have suggested the outbreak is unlikely to have a significant long-term impact on Taco Bell's parent company, Yum Brands, given the swift response and the relatively contained nature of the supply chain issue. Public health experts, however, are emphasizing that consumers who purchased iceberg lettuce from any source linked to Taylor Farms' Mexican operations should monitor their health closely.
