A Fox News Digital article reports that Wisconsin officials confirmed highly pathogenic avian influenza in a backyard poultry flock in Rusk County and euthanized all birds on the property, which will not enter the food system, without saying how the flock was infected. The Wisconsin Department of Agriculture, Trade and Consumer Protection, which says the virus has circulated in North America since December 2021, urged owners to disinfect equipment, restrict access to animals, quarantine new birds for at least 30 days, and keep poultry indoors when possible.
