Columbia River Natural Pet Foods of Vancouver, Washington, U.S.A. is voluntarily recalling 933 packages of Cow Pie fresh frozen meats for dogs and cats, produced in August 2017, because it has the potential to be contaminated with Listeria monocytogenes, according to the United States Food and Drug Administration.

Cow Pie is a fresh frozen meats product intended to feed raw to dogs and cats. Cow Pie was distributed in Alaska, Oregon, and Washington through retail stores and direct delivery. The recalled pet food comes frozen in 2 lbs. purple and white plastic bags, with Lot 81917 (processed on August 19, 2017) found on an orange sticker.

No illnesses have been reported to date. The potential for contamination was noted after routine testing by the Washington State Department of Agriculture revealed the presence of Listeria monocytogenes in one package.

Effects of Listeria in pet food

Listeria monocytogenes may affect animals eating the products and there is risk to humans from handling contaminated pet products, especially if they have not washed their hands after having contact with the products or any surfaces exposed to this product.

Listeria monocytogenes can be pathogenic to humans. Listeria monocytogenes is one of the leading causes of human death from foodborne illness. Healthy people infected with Listeria monocytogenes should monitor themselves for some or all of the following symptoms: nausea, vomiting, aches, fever, and diarrhea. Listeria monocytogenes infections can also spread through the bloodstream to the nervous system (including the brain), resulting in meningitis and other potentially fatal problems. Pregnant women are more susceptible to Listeria infection, which can result in abortion. The young, the elderly, and people with weakened immune systems also are more vulnerable. Consumers exhibiting these signs after having contact with this product should contact their healthcare providers.

Although uncommon, pets with Listeria monocytogenes infections may display symptoms such as mild to severe diarrhea, anorexia, fever, nervous, muscular and respiratory signs, abortion, depression, shock, and death. Animals that recover may become carriers and serve as potential sources of infection to other animals. In addition to the possibility of becoming sick, such infected animals can shed Listeria monocytogenes through their feces onto their coats and into the home environment and thus serve as sources of infection to humans and other animals in the household. If your pet has consumed the recalled product and has these symptoms, please contact your veterinarian.
