Pico Rivera, CA-The FDA, along with CDC and state and local partners, investigated a multistate outbreak of Salmonella Litchfield infections linked to fresh, raw salmon supplied to restaurants in California and Arizona by Mariscos Bahia, Inc.

On December 14, 2022, CDC announced that the outbreak is over. CDC reports a total of 39 illnesses in four states. The last illness onset was October 23, 2022.

As part of this investigation, the FDA and the California Department of Public Health conducted a joint inspection at Mariscos Bahia, Inc., Pico Rivera, CA, and collected environmental samples from the facility. Multiple samples collected from the firm came back positive for Salmonella. Whole Genome Sequencing (WGS) indicated the Salmonella detected in at least one of the swabs from the facility matched the strain causing illnesses in this outbreak. The epidemiological evidence indicated that ill people consumed fresh, raw salmon processed at this firm; however, the presence of Salmonella in the processing environment also indicated that additional types of fish processed in the same area of the facility could have been contaminated.

On October 20, 2022, Mariscos Bahia, Inc., Pico Rivera, CA initiated a voluntary recall. Recalled products included fresh, raw salmon along with all other types of fresh fish processed in the same area as the salmon which included fresh, raw halibut, Chilean seabass, tuna, and swordfish.

Recommendation

According to Mariscos Bahia, Inc., seafood was only sold directly to restaurants in California and Arizona and would not be available for purchase by consumers in retail stores. The firm contacted direct restaurant customers that received the recalled product. Recalled seafood was sold fresh and is now past shelf-life unless it was frozen after purchase.

Restaurants that might have purchased or received recalled fresh, raw salmon, halibut, Chilean seabass, tuna, or swordfish from Mariscos Bahia, Inc. (Pico Rivera, CA, and Phoenix, AZ) between June 14 - October 17, 2022, should check their freezers and throw away the recalled product. Restaurants should also be sure to wash and sanitize locations where recalled fish from Mariscos Bahia, Inc. were stored or prepared.
