The Washington State Department of Agriculture and the Oregon Department of Agriculture have issued a public health alert because of H5N1 influenza virus contamination of another brand of raw pet food, following the deaths of two more indoor cats from separate households linked to consumption of the pet food.
Details are sparse, but both cats were euthanized due to severe disease from H5N1 influenza. Authorities tested the cats and the food from open containers in the household as well as unopened food samples, and found H5N1 flu virus in all of them. This shows that the food was truly contaminated at the source, and removes the potential that the food got contaminated in the household by the cats or some other source. (In a previous raw food-associated cluster of H5N1 flu infections in cats, the manufacturer of the implicated food tried to suggest the diet was contaminated in the household and was not the source of the virus, which was a very weak argument, and definitely not the case here based on the additional testing).
The recall involves Wild Coast LLC Boneless Free Range Chicken Formula, lots 22660 and 22664, Best Buy day 12/25. However, given that we have multiple instances of fatal raw poultry associated H5N1 infections in cats from multiple companies, the risk probably extends beyond this product.
To avoid the risk of H5N1 influenza from raw pet foods:
- If raw diets are to be fed, use a non-poultry based diet, and choose one that’s high pressure pasteurized to reduce (though it will not eliminate) the risk.
