Avian Flu Testing in Indiana
In May 2015, avian influenza virus (AIV) was detected in a backyard, mixed poultry flock in Whitley County, Indiana. The Board of Animal Health (BOAH) confirmed that approximately two-thirds of the flock was positive for a highly pathogenic subtype of AIV, H5N8. The BOAH depopulated the entire flock and after extensive surveillance and testing by both BOAH and the Indiana Division of Fish & Wildlife (DFW) in both domestic and wild birds within a 10 km (6.2 mi) radius buffer around the positive flock, BOAH lifted the quarantine for the Whitley County case.
On Jan. 15, 2016 AIV was detected in a commercial turkey facility in Dubois County, Indiana. The birds within the facility tested positive for highly pathogenic avian influenza subtype H7N8, which is a new North American subtype. A 10 km control area and a 20 km surveillance zone were established around the positive facility. Subsequent testing within the control area by the BOAH and Animal and Plant Health Inspection Service (APHIS) identified eight turkey facilities that tested positive for a low pathogenic avian influenza, H7N8. While the BOAH and APHIS tested domestic flocks and wildlife on the positive premises, the DFW began testing wild birds within both control area and surveillance zone. As of Feb. 15, 2016:
- No additional facilities tested positive for AIV. Eleven poultry facilities were depopulated within the control area due to detection of the highly pathogenic H7N8 (one facility), detection of the low pathogenic H7N8 (in eight commercial turkey facilities), or proximity (one commercial turkey facility and one commercial chicken facility) to the positive highly pathogenic H7N8 facility.
- No wild birds sampled by DFW have tested positive for the highly pathogenic subtypes H5 or H7. The DFW has tested 126 wild birds both within and outside of the control area and surveillance zone.
- Surveillance will continue within the established control area/surveillance zone by all entities until the BOAH lifts the 10 quarantines.
In addition to active sampling associated with a highly pathogenic avian influenza site, DFW personnel are conducting opportunistic sampling of wild birds across the state for AIV. Opportunistic sampling consists of collecting wild birds at various locations that meet specific criteria. DFW staff collects individual waterfowl, shorebirds, gallinaceous birds (grouse, pheasant, wild turkeys) and raptors that have died of unknown causes. In addition, DFW staff collects songbirds that have died of unknown causes during a mortality event of at least five birds at one time.
The map identifies the locations of all wild bird specimens sampled for AIV in Indiana. This map will be updated periodically based on sampling efforts.
If you find a raptor, a species of waterfowl, shorebird or gallinaceous bird, or if you find a group of at least five songbirds that have died of an unknown cause, please call the DFW Office at (812) 334-1137 or email dfwinput@dnr.IN.gov.
