FAIRFIELD, CALIF. — On July 6, Primal Pet Foods issued a voluntary recall in cooperation with the US Food and Drug Administration (FDA) involving a select lot of its Raw Frozen Primal Patties for Dogs Beef Formula due to potential contamination with Listeria monocytogenes.

The impacted product is sold in 6-lb packs with a best by date of 5/22/23 and a lot code of W100068709, located on the back of the packaging. Primal is urging those with the impacted products to dispose of them immediately. No other products or lot codes have been impacted by the recall.

About 396 units of the product were distributed to Maryland, Georgia, Texas and British Columbia in late April of this year.

Primal was prompted to issue the recall after routine sampling by the FDA revealed a positive result of Listeria, though the company confirmed several negative Listeria monocytogenes tests of its Raw Frozen Primal Patties before the product left its facilities. The company uses a “test and hold” method to help prevent contaminated food and harmful bacteria from making its way into the market.

According to Primal, it has not received any reports of illness to pets or humans as a result of the recall.

Listeria monocytogenes bacteria rarely results in illness in dogs, according to the FDA, but dogs can still experience symptoms and spread the illness to humans. Symptoms for dogs includes diarrhea and vomiting. The pathogen can spread to humans via handling of the contaminated food or by touching food-contact surfaces.
