Federal officials said shredded iceberg lettuce served at Taco Bell in Indiana, Kentucky, Michigan, Ohio and West Virginia was confirmed as a source of the cyclospora outbreak and urged consumers not to eat it.
FDA traced the lettuce to a single Mexican supplier, and a federal official identified that company as Taylor Farms of Salinas, California; Taco Bell said it would stop using lettuce from the supplier.
CDC said potentially contaminated shredded iceberg lettuce could still be on the market through other channels, and warned that more brands, restaurants or retailers could be tied to the investigation.
More than 30 states have reported cyclospora infections this year, with the national total already surpassing the previous U.S. record of about 4,700 cases set in 2019.
