An Oregon house cat died after eating pet food that tested positive for bird flu, Oregon authorities said, prompting a recall of raw frozen pet food that was sold nationwide.

Northwest Naturals, a pet food company based in Portland, Oregon, said Tuesday it had voluntarily recalled one batch of its two-pound Feline Turkey Recipe raw frozen pet food after it tested positive for the virus. The product was sold through distributors in Arizona, California, Colorado, Florida, Georgia, Illinois, Maryland, Michigan, Minnesota, Pennsylvania, Rhode Island and Wisconsin, as well as Canada's British Columbia.

“We are confident that this cat contracted H5N1 by eating the Northwest Naturals raw and frozen pet food,” Oregon Department of Agriculture State Veterinarian Dr. Ryan Scholz said in a Tuesday news release. “This cat was strictly an indoor cat; it was not exposed to the virus in its environment, and results from the genome sequencing confirmed that the virus recovered from the raw pet food and infected cat were exact matches to each other.”

The recalled product is packaged in two-pound plastic bags with “best if used by” dates of May 21, 2026, and June 23, 2026. The company and Oregon authorities said that consumers who bought the recalled product should throw it away immediately and contact the place of purchase for a refund, The AP reported.

No human cases of bird flu have been linked to the incident, but those who were in contact with the cat are being monitored for flu symptoms, Oregon authorities said.

More than 60 people in eight states have been infected, with mostly mild illnesses, according to the US Centers for Disease Control and Prevention, or CDC. One person in Louisiana has been hospitalized with the nation’s first known severe illness caused by the virus, health officials said last week.

So far, the CDC has confirmed one human case of bird flu in Oregon. The person was linked to a previously reported outbreak at a commercial poultry operation and fully recovered after experiencing mild illness, according to a November news release from the Oregon Health Authority.

In late October, the US Department of Agriculture announced that a pig at a backyard farm in Oregon was found to have bird flu, marking the first detection of the virus in US swine.

The US Centers for Disease Control and Prevention said on Thursday its analysis of samples from the first severe case of bird flu in the country last week showed mutations not seen in samples from an infected backyard flock on the patient's property.

The CDC said the patient's sample showed mutations in the hemagglutinin (HA) gene, the part of the virus that plays a key role in it attaching to host cells.

The health body said the risk to the general public from the outbreak has not changed and remains low, according to Reuters.

Last week, the United States reported its first severe case of the virus, in a Louisiana resident above the age of 65, who was suffering from severe respiratory illness.

The patient was infected with the D1.1 genotype of the virus that was recently detected in wild birds and poultry in the United States, and not the B3.13 genotype detected in dairy cows, human cases and some poultry in multiple states.

The mutations seen in the patient are rare but have been reported in some cases in other countries and most often during severe infections. One of the mutations was also seen in another severe case from British Columbia, Canada.

No transmission from the patient in Louisiana to other persons has been identified, said the CDC.
