Northwest Naturals is recalling a line of its pet food after authorities Oregon linked the death of a cat to a batch contaminated with bird flu.

The rising incidence of bird flu in the Central Valley is raising serious concerns for public health and food safety. The detection of the virus in dairy cattle has sparked alarm, as it increases the risk of transmission to other animals and potentially to humans.

Northwest Naturals issued a voluntary recall for a batch of pet food after a cat died of bird flu in Oregon, officials said. Testing done by the U.S. Department of Agriculture's National Veterinary Services Laboratories and the Oregon Veterinary Diagnostic Laboratory confirmed an indoor cat in Oregon's Washington County contracted bird flu and died after eating the pet food.
