On May 31, the Indiana State Board of Animal Health (BOAH) lifted quarantines on all avian premises within a 3 km radius of a Whitley County site that was infected with highly pathogenic avian influenza (HPAI) H5N8. Likewise, movement restrictions on all sites in the 10 km control area have been lifted.
The avian quarantines were in effect from May 9 to May 31, after a backyard poultry flock was diagnosed. The 21-day period after the infected site was cleared of birds reflects the maximum incubation period for HPAI, and is required by USDA standards. During this period, all birds in the 3 km infected zone were tested twice for HPAI and all tests were negative. This included 30 avian premises.
In addition, six flocks that supplied birds to the infected site also tested negative, and have been released from quarantine. Indiana Department of Natural Resource (DNR) biologists have tested (all negative) wild birds and environmental samples on and around the infected site. DNR will continue wild bird monitoring through the summer.
Surveillance and ReportingBOAH reminds bird owners to remain vigilant in looking for signs of HPAI illness in wild and domestic birds. Hoosiers who notice five or more dead wild feeder-type birds should call the Indiana Department of Natural Resources at: 812-334-1137.
Owners of small/backyard poultry flocks can help by reporting any unusual deaths or illness to the USDA Healthy Birds Hotline: 866-536-7593. Callers will be routed to a federal or state veterinarian in Indiana for case assessment. Dead birds should be double-bagged and refrigerated for possible testing.
