US FDA traceback data as of July 20 pointed to shredded iceberg lettuce from Taylor Farms facilities in central Mexico as the source of a cyclosporiasis outbreak affecting Taco Bell restaurants in five states, with approximately 100 hospitalizations reported by the CDC. Mexico's Health Minister stated on July 21 that no evidence supported Mexican lettuce as the cause, following an FDA false positive on one sample. A Michigan lawsuit has been filed against Taco Bell and Taylor Farms.
