Chris Koger of The Packer writes the U.S. Food and Drug Administration will be collecting romaine samples in California and Arizona for a year to test for salmonella and E. coli following several foodborne outbreaks linked to the lettuce.
The new program begins this month, according to the FDA, citing two E. coli outbreaks in 2018 linked to romaine, and another one in October that was suspected to be from the leafy green. In its notice on the surveillance program, the FDA also cited a 2012 Salmonella Newport outbreak from romaine.
“Consistent with the FDA’s mission to protect consumers, if one of the target pathogens is detected as a result of this assignment, the agency will perform whole genome sequencing of the microorganism’s DNA to determine its virulence and whether it is genetically related to isolates causing human illness,” according to the notice.
All samples will be tested before processing to allow the FDA to quickly find the point of origin, which has been problematic in recent outbreaks as public and federal health agencies traced lettuce through the supply chain. In part, traceability hurdles have led to the FDA’s New Era of Smarter Food Safety program, which tasks the industry with enhancing traceability methods and technology.
Trimmed and washed lettuce will be tested, but not fresh-cut lettuce, and no lettuce at the farm-level will be involved in the surveillance program.
Samples will be targeted at facilities and farms identified in the outbreaks starting in 2017, including wholesalers, foodservice distribution centers, and commercial cooling and cold storage facilities, according to the FDA notice.
