Today the FDA announced a new plan to collect samples of romaine lettuce as part of its ongoing surveillance after the spring 2018 multistate outbreak of E. coli O157:H7. The samples, which will be tested for Shiga toxin-producing Escherichia coli (STEC) and Salmonella, will be collected from commercial coolers in Yuma County, Arizona during the current harvest season.

FDA plans to collect and test about 500 samples (each of which will consist of 10 subsamples), beginning in February and continuing through the end of the harvest season. In order to reduce the time between sample collection and reporting results, an independent lab close to the collection sites in Arizona will be testing the samples. FDA expects to receive test results within 24 hours.

“Helping to ensure the safety of leafy greens continues to be a priority of the FDA. This assignment adds to other work underway in collaboration with stakeholders in the Yuma agricultural region to implement actions identified in the Leafy Greens Action Plan, including a multi-year study to assess the environmental factors that impact the presence of foodborne pathogens in this region. Consistent with the action plan, the agency will engage with industry on conducting root cause analyses for any positive samples found during this assignment. Root cause analyses are important in that they seek to identify potential sources and routes of contamination, inform what preventive measures are needed, and help prevent outbreaks of foodborne illness,” FDA stated in a release.

COVID-19 precautions will be taken during the sampling plan. Agency investigators will preannounce visits and wear PPE while conducting the work.

FDA Issues Update on E. Coli Outbreak Involving Leafy Greens

FDA has completed its investigation of the multistate outbreak of E. coli 0151:H7 that occurred last fall and was linked to leafy greens. The FDA and CDC found the outbreak was caused by an E. coli strain that was genetically related to the strain found in the fall 2019 outbreak involving romaine lettuce (Salinas, California). Despite conducting environmental sampling at dozens of ranches in the area, the FDA was unable to identify a single site as the source of the outbreak. However, the analysis did confirm “a positive match to the outbreak strain in a sample of cattle feces,” which was located uphill from where the leafy greens identified in the agency’s traceback investigation were grown, according to an FDA release.

Although the FDA’s investigation has ended, the agency will be reviewing the findings and release a report in the “near future” with recommendations. “In the meantime, as recommended in our Leafy Greens Action Plan, the FDA continues to recommend growers assess and mitigate risk associated with adjacent and nearby land use practices, particularly as it relates to the presence of livestock, which are a persistent reservoir of E. coli O157:H7 and other STEC,” FDA stated in the update.
