Oregon Department of Agriculture, in cooperation with the US Department of Agriculture, is responding to a detection of highly pathogenic avian influenza (HPAI) in a flock of backyard birds near Tumalo in Deschutes County. ODA, working with the USDA’s Animal Health Inspection Service (APHIS), is in the process of setting up a quarantine zone around the property to restrict movement of domestic birds in and out of the area. Currently, the property is secured and there have been no additional detections of HPAI in the area.

The flock of about 90 mixed poultry and other domestic birds includes chickens, ducks and turkeys that have had access to a couple of ponds on the property that are also frequented by migratory wild waterfowl. Avian influenza naturally resides in wild birds and it is fairly common for waterfowl to carry various strains of the virus. HPAI has also been reported in backyard birds in Washington and Idaho, and in wild birds in all three Pacific Northwest states.

The Deschutes County detection is the second in Oregon. HPAI was detected in a flock of backyard birds in Douglas County in December.
