The USDA is taking precautions by testing the beef supply after an outbreak of avian flu in dairy cows. While the agency believes the meat supply is safe, it is sampling ground beef in the states where the H5N1 virus has been detected. The Highly Pathogenic Avian Influenza, also known as bird or avian flu, can be transmitted by wild birds to domestic poultry and other animals.
The USDA is specifically testing ground beef sold at retail in the nine states where the bird flu virus was found in dairy cows, including Idaho, Kansas, Michigan, New Mexico, and Texas. Using polymerase chain reaction (PCR) tests, the agency is checking for any signs of the virus in these samples. This is one of three studies the USDA is conducting to ensure beef safety in light of the recent H5N1 outbreak in dairy cows.
To further ensure consumer safety, food safety officials are also testing muscles from culled dairy cows that were infected with bird flu at slaughter facilities. Food Safety and Inspection Service veterinarians are present at all federal livestock slaughter facilities to inspect animals before and after slaughter to ensure their health and safety.
In addition to testing meat and muscles, another study by USDA scientists will evaluate how different cooking temperatures affect virus reduction. Consumers are reminded to properly handle raw meats and cook them to a safe internal temperature to kill any bacteria or viruses present.
The results of these studies will be shared with the public once available. These precautionary measures follow
