Register now for the complimentary virtual event in our Food Safety Hazards Series, “Salmonella Detection, Mitigation, Control and Regulation” | Thursday, July 15, 11:45 am ETAs 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.

FDA Issues Update on E. Coli Outbreak Involving Leafy Greens

FDA

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.

E. Coli Outbreaks Linked to Salinas-Grown Romaine Lettuce Over, Deputy Commissioner Yiannas Releases Statement

Yesterday the CDC reported that the E.coli outbreak linked to romaine lettuce grown in the Salinas, CA growing region is over. The contaminated lettuce should no longer be available, and FDA states that consumers do not need to avoid romaine lettuce from Salinas. The agency will continue its investigation into the potential factors and sources that led to the outbreak.

The FDA did identify a common grower link to the E.coli O157:H7 contamination as a result of its traceback investigation. However, a statement released yesterday by FDA Deputy Commissioner for Food Policy and Response Frank Yiannas points out that “this grower does not explain all of the illnesses seen in these outbreaks.”

To be specific, the FDA, CDC and other public health agencies were tracking three outbreaks involving three separate strains of E.coli O157:H7 linked to romaine lettuce. During the course of the investigation FDA, CDC, the California Department of Food and Agriculture and the California Department of Public Health conducted sampling of the water, soil and compost of several of the fields in the lower Salinas Valley that were connected to the outbreak. “So far, sample results have come back negative for all of the three outbreak strains of E. coli O157:H7. However, we did find a strain of E. coli that is unrelated to any illnesses in a soil sample taken near a run-off point in a buffer zone between a field where product was harvested and where cattle are known to occasionally graze,” Yiannas said in the agency statement. “This could be an important clue that will be further examined as our investigation continues. However, this clue does not explain the illnesses seen in these outbreaks.”

Finding the contamination source(s) is critical, as it will aid romaine growers in putting safeguards in place to help prevent future contamination.

As for the final case count (with last illness onset on December 21, 2019) of this outbreak, there were 167 total illnesses and 85 hospitalizations across the United States. No deaths were reported.

Lettuce

In the latest FDA update about the E. coli O157:H7 outbreak involving romaine lettuce, the agency has stated that consumers should not eat romaine lettuce that has been harvested from Salinas, California. Traceback investigations related to three different E. coli outbreaks (three different strains, all of which involve romaine lettuce) have pointed to a common grower located in Salinas. Frank Yiannas, deputy commissioner for food policy and response, called the identification of a common grower a “notable development” but also stated in a press announcement, “Because of the expansive nature of these outbreaks, our investigation remains a complicated work in progress, and it is too soon to draw definitive conclusions.”

FDA, CDC and California partners have sent out a team to conduct new investigations at ranches used by the grower as part of the process in finding the contamination source, according to an FDA update.

Thus far, 102 illnesses have been reported across 23 states, with 58 hospitalizations. No deaths have been reported. The last illness onset was reported on November 18.

Thus far Swedesboro, NJ-based Missa Bay, LLC has recalled more than 75,000 pounds of salad products because of a lettuce ingredient that might be contaminated with E. coli O157:H7. This lettuce was also found to be in packaged salad that the Maryland Department of Health said contained E. coli.

FDA states that thus far lettuce grown indoors has not been indicated in the outbreak.
