FDA to Begin Testing Samples of Salinas-Grown Lettuce for E. Coli and Salmonella
Watch the on-demand complimentary virtual event in our Food Safety Hazards Series, “Salmonella Detection, Mitigation, Control and Regulation” (Original air date: Thursday, July 15, 2021)As part of ongoing surveillance efforts resulting from recurring outbreaks, the FDA announced that it will conduct direct sampling and testing of lettuce grown in the Salinas Valley region of California. From May through November 2021, the agency will test samples for Shiga toxin-producing Escherichia coli (STEC), including E. coli O157:H7, and Salmonella spp. Direct sampling will be conducted at commercial cooling and cold storage facilities where field heat is removed from harvested lettuce and product is cold-stored prior to processing. “Sample collection at commercial coolers helps the FDA efficiently obtain samples from multiple farms at centralized locations and facilitates prompt traceback and follow-up if contamination is detected,” according to a CFSAN update.
FDA laboratories plan to test about 500 post-harvest samples of iceberg, leaf and romaine lettuce, with each sample consisting of 10 subsamples (one head of lettuce that is trimmed, cored or wrapped; or romaine lettuce leaves or one package of hearts).
In compliance with COVID-19 safety practices, the agency investigators will preannounce their visits.
