Whole Foods Market is recalling an additional lot code (for a total of two lot codes) of Whole Catch Wild Alaskan Sockeye Salmon which were sold in stores in 18 states, because it may contain Listeria Monocytogenes, an organism which can cause a sometimes fatal infection in young children, frail or elderly people, and others with weakened immune systems.

Although healthy individuals may suffer short term symptoms, such as high fever, severe headaches, nausea, abdominal pain and diarrhea, Listeria infection can cause miscarriages and stillbirths among pregnant women.

The recall is for 4 ounce pages, UPC code 0 99482 40880 0 and it includes cold smoked and sliced. The first lot code, 7425A2298B, was recalled on Fri., Jan. 25, and was sold in stores in Colorado, Connecticut, Florida, Idaho, Kansas, Maine, Massachusetts, New Jersey, New Mexico, New York, Rhode Island, and Utah.

Named in this updated recall is a second lot code, 7425A2297A. According to Whole Foods Market, products with this lot code were sold in stores in Arkansas, California, Colorado, Idaho, Kansas, Louisiana, Nevada, New Mexico, Oklahoma, Texas, and Utah.

Both lot codes of the recalled salmon were sold in black-and-gold, flat, rectangular vacuum-sealed packages. The lot codes are ink-jet printed on the back of the package, on the upper left side. Signage is posted in Whole Foods Market stores to notify customers of this recall.

The company said that no illnesses have been reported “related to these lot codes,” but a sample of the product tested positive for listeria.

The company is asking customers to dispose of the product in the garbage and wash their hands immediately to avoid any potential cross-contamination. Full refunds will be given at the store.
