The Idaho State Department of Agriculture (ISDA) has lifted the quarantine zone in Canyon County, covering an area of approximately six miles around a site near Parma, Idaho, where avian influenza was confirmed in a backyard flock of chickens.

All surveillance and testing requirements have been met and no new domestic birds have been diagnosed with avian influenza. The quarantine restricted the movement of avian species within and out of the identified zone.

Poultry producers may now move poultry and poultry products without restrictions, the department stated. ISDA encourages bird owners to continue to protect their domestic birds from contact with wild waterfowl and remain vigilant in their biosecurity measures.


The state has seen outbreaks of both H5N8 and H5N2 avian influenza. The virus was initially confirmed in Idaho in January. In addition to affecting a backyard flock of chickens, avian influenza has also been confirmed in wild ducks in Gooding County and in falcons in Canyon County.

To date, avian influenza cases have been confirmed in Idaho, Washington, Oregon, California, Utah and Nevada, as well as in the Canadian province of British Columbia. Only one commercial poultry operation – a Foster Farms turkey operation in California -- has had an infection of avian influenza.
