The FDA stated on July 20, 2026, that it continues to believe that Taylor Farms lettuce is likely associated with a Cyclospora outbreak, despite retracting earlier test results that linked the produce to the parasite. The outbreak has affected at least 1,644 individuals, with officials suggesting the actual number may be higher. Taylor Farms has voluntarily recalled shredded iceberg lettuce sourced from central Mexico in connection with the outbreak.
Laboratory results are just one aspect of foodborne outbreak investigations, which also involve tracing illnesses and food shipments. A sample that was initially flagged as positive was later determined to be a false positive and was not part of the current recall. However, FDA officials maintain that the data supporting the outbreak advisory remains valid. The CDC continues to advise consumers to avoid recalled products, including those served at Taco Bell, which has removed the affected lettuce from its restaurants.
The FDA has acknowledged the difficulties in tracking Cyclospora in food, citing factors such as the short shelf-life of fresh produce and the lengthy incubation period for symptoms. The investigation is ongoing, with officials exploring other potential sources of illness.
