Immunocompromised persons may experience more severe illness of longer duration along with complications requiring close medical attention.

Current Update
July 16, 2026
The FDA and CDC, in collaboration with state and local partners, are investigating a multistate outbreak of Cyclospora illnesses linked to shredded iceberg lettuce served at Taco Bell locations in Indiana, Kentucky, Michigan, Ohio, and West Virginia. The illnesses included in this outbreak are a subset of the Cyclospora illnesses identified nationwide.
Based on epidemiological information collected by CDC, a total of 1,644 people infected with Cyclospora and reporting exposure to Taco Bell have been reported by five states. Illnesses started on dates ranging from May 13, 2026, to July 13, 2026. There have been 94 hospitalizations, and no deaths have been reported. MI analyzed food exposure details from 190 of the cases who reported eating at Taco Bell and shared these findings with CDC. Ingredient level analyses on meals eaten by these cases indicate that 90% of those interviewed reported eating iceberg lettuce.
FDA’s traceback investigation has identified convergence on a single supplier of iceberg lettuce from Mexico used by Taco Bell locations where sick people ate before becoming ill.
FDA is working directly with the identified supplier to determine if potentially contaminated shredded iceberg lettuce remains on the market. As part of this investigation, FDA and state partners have initiated collection of product samples for testing and analysis. Additionally, FDA has increased screening at the border for products implicated in the outbreak.
FDA is also working with Taco Bell and they have committed to stop using any lettuce from the supplier identified by FDA’s traceback investigation.
FDA and state partners are actively investigating the source and scope of the contamination. Because the investigation remains ongoing, additional implicated brands, restaurants, retailers, or distribution channels may be identified as the investigation continues. This advisory will be updated promptly as new information becomes available.
FDA is aware that the case counts in this advisory may not match what is being reported by individual states. State data may include both probable and confirmed cases, while CDC and FDA include confirmed cases only. State case counts may also include initial case reports that have not yet been reported to CDC. As cases are confirmed, these numbers will continue to update.
Additionally, 2026 national surveillance numbers reported by the CDC track laboratory-confirmed cases in the U.S. overall, which include this outbreak as well as illnesses that are not a part of this outbreak.
