As of July 21, Indiana has achieved free status for highly pathogenic avian influenza (HPAI). This designation, as listed with the World Organization for Animal Health (WOAH, formerly OIE), allows exports and international trade for Indiana poultry products to be restored.

Poultry owners should note that a HPAI-free status is NOT an “all clear” or an indication that the risk of the disease is over in Indiana or the United States. Owners of all flocks, large and small, need to remain vigilant in biosecurity and preventing introduction of the virus.

The influenza virus is still very active throughout parts of the United States. HPAI has been identified on 395 poultry sites in 38 states since February. Wild birds infected with HPAI have been found from coast to coast in various species, including waterfowl (ducks, swans, geese, gulls, etc.), raptors (hawks and eagles), as well as other common species (American robin, common raven, wild turkey).

Steps should be taken to minimize wild-bird exposure to poultry as much as possible. Nationally, concern is growing that another wave of HPAI cases could crop up when fall migration begins.


The first HPAI case of 2022 in Indiana—and the nation—was confirmed in early February in a Dubois County turkey flock. To date, Indiana has had nine commercial poultry flocks (ducks and turkeys) and four small/hobby flocks (mixed species) test positive for HPAI in five counties. All commercial sites have been cleared to restock at the owner’s discretion. All control areas and surveillance zones have been released.

Under WOAH guidelines, HPAI-free status can be declared for a state or region after the disease has been eliminated on all affected farms and no new infections are detected during a minimum waiting period of 28 days.

Since February, the Indiana State Board of Animal Health has been working with multiple state and federal partners to respond to this event, including Indiana Department of Health, Indiana Department of Homeland Security, Indiana Department of Natural Resources, Indiana Department of Environmental Management, and USDA Veterinary Services, Wildlife Services and Farm Service Agency.
