Highly pathogenic avian influenza has been found in a non-commercial backyard poultry flock in Colorado, the USDA confirmed in a statement on Saturday, amid the worst U.S. outbreak of the virus in seven years.

State officials quarantined the premises in Pitkin County, and birds from the flock will be “depopulated to prevent the spread of the disease.”
