State of Indiana
Response to
Highly Pathogenic Avian Influenza
2025
(29 May 2025)
Update #49
INDIANA DECLARES HPAI-FREE STATUS
As of May 27, Indiana may declare freedom from highly pathogenic avian
influenza (HPAI). This designation, relative to standards set forth by the World
Organization for Animal Health (WOAH), eases export restrictions and
international trade barriers for Indiana poultry and poultry products.
Poultry owners should note that 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
in preventing the introduction of the virus. The influenza virus is still active
throughout parts of the United States. HPAI has been identified in poultry on
1,702 premises in all 50 states and Puerto Rico since February 2022, with new
cases reported as recently as last week. Wild birds infected with HPAI have
been found from coast to coast in various species, including waterfowl (ducks,
geese, swans), raptors (eagles, hawks, falcons, vultures), shorebirds, seabirds,
and other species commonly found in Indiana. Steps should be taken to
minimize wild bird exposure to poultry as much as possible. Furthermore, last
March, the USDA confirmed the first detection of HPAI in a Texas dairy herd.
The total confirmed detections in domestic livestock—almost exclusively dairy
cattle—now include 1,074 premises in 18 states. HPAI has also been found in
several other species of wild and captive mammals across the country.
The first HPAI case of the 2022-2025 incident in Indiana—and the nation—was
confirmed in early February 2022 in a Dubois County turkey flock. Indiana has
had 34 commercial poultry flocks (chickens, ducks, and turkeys) and 11
small/hobby flocks (mixed species) test positive for HPAI in 20 counties. Of
those 45 cases, 27 were diagnosed in 2025. Indiana has not diagnosed a case
of HPAI in livestock.
All control areas and surveillance zones have been released, and most farms
have been cleared to restock. 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 in a subsequent 28-day
waiting period.
