Highly Pathogenic Avian Influenza (Bird Flu) Confirmed in California Backyard Flock

Following an investigation by the California Department of Food and

Agriculture (CDFA), the U.S. Department of Agriculture’s National Veterinary Services Laboratories (NVSL) has confirmed highly pathogenic avian influenza (HPAI) in a backyard flock in Sacramento County.

In addition to this confirmation, HPAI has also been detected in wild birds in the following twelve counties: Butte, Colusa, Glenn, Mendocino, Placer, Plumas, Sacramento, Santa Clara, Siskiyou, Solano, Sonoma, and Stanislaus. The viral spread is promoted by wild birds especially in wild waterfowl such as

ducks and geese, but many other wild bird species can also be a source of spread. Poultry owners can protect their flocks by increasing their biosecurity practices.

To protect other flocks in California, the confirmed infected location is currently under quarantine, and the birds have been euthanized to prevent further disease spread. Read more
