The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic avian influenza (HPAI) in a commercial turkey flock in Dubois County, Indiana. This is the first confirmed case of HPAI in commercial poultry in the United States since 2020.
Samples from the affected flock, which experienced increased mortality, were tested at the Indiana Animal Disease Diagnostic Laboratory at Purdue University, part of the National Animal Health Laboratory Network, and confirmed at the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa. Virus isolation is ongoing.
Important details of the confirmed case:
- APHIS is working closely with the Indiana Board of Animal Health on a joint incident response.
- State officials quarantined the affected premises, and
- birds on the property were depopulated to prevent the spread of the disease
- Birds from the flock will not enter the food system.
As part of existing avian influenza response plans, Federal and State partners are working jointly on additional surveillance and testing in the nearby area.
The United States has the strongest AI surveillance program globally, and USDA is working with its partners to actively look for the disease in commercial poultry operations, live bird markets, and migratory wild bird populations.
Anyone involved with poultry production, from the small backyard to the large commercial producer should review their biosecurity activities to assure the health of their birds. APHIS has materials about biosecurity, including videos, checklists, and a toolkit available at APHIS.
