A sample of shredded iceberg lettuce from Taylor Farms de Mexico has tested positive for cyclospora, the FDA announced. Federal officials noted this specific sample is not included in the company’s voluntary recall announced on July 17.
The contaminated lettuce was collected through targeted import surveillance. The FDA investigation has now raised questions about potential wider risk. Taylor Farms is working to identify if any part of the implicated lot is in commerce or in homes.
The investigation previously identified Taylor Farms de Mexico as the common supplier of lettuce served at Taco Bell restaurants, where infected customers reported eating. The company voluntarily removed all iceberg lettuce sourced from central Mexico from the U.S. market.
Taco Bell removed all lettuce supplied by Taylor Farms from its restaurants. Walmart removed select Marketside iceberg lettuce products from stores in 27 states as a precaution. Recalled Walmart products include Marketside Iceberg Salad and Shredded Lettuce with specific Best-by dates.
Cyclospora is a microscopic parasite causing gastrointestinal illness. The outbreak has sickened people across 34 states. Federal investigators continue to determine if products from the positive lot reached consumers.
