HPAI Detection in Idaho Dairy Herd

Boise, Idaho – The Idaho State Department of Agriculture (ISDA) identified today highly pathogenic avian influenza (HPAI) in a Cassia County dairy cattle operation.

These are the first cases of HPAI in a livestock operation in Idaho. The affected facility recently imported cattle from another state that has identified cases of HPAI in cattle, which suggests the virus may be transmitted from cow-to-cow, in addition to previous reports indicating cattle were acquiring the virus from infected birds.

The primary concern with this diagnosis is on-farm production losses, as the disease has been associated with decreased milk production.
