Investigation of 5-State Outbreak of Cyclospora Illnesses: Iceberg Lettuce
Do not eat recalled iceberg lettuce from Taylor Farms de Mexico. FDA’s investigation is ongoing.
July 19, 2026
FDA is providing an update regarding the sample of lettuce supplied by Taylor Farms de Mexico which was reported positive on July 18, 2026. Due to the complexity in detection of Cyclospora, FDA laboratory experts re-reviewed the sample results and have concluded that the finding does not represent true amplification and should be considered a false positive. Information about the sample has been removed from the July 18, 2026 update. FDA has notified Taylor Farms and continues working with the firm to ensure product implicated in this outbreak has been removed from the market. FDA and state partners continue to collect and analyze product samples. As of July 19, 2026, there are no confirmed positive sample results for product testing for Cyclospora.
