What should I do if I suspect avian influenza in my flock?

Hoosier poultry owners should contact the Animal Disease Diagnostic Laboratory at Purdue University, (765) 494-7440, to submit dead birds for testing. A veterinary referral is not required for poultry and exotic bird species.

Introduction and Spread of Avian Influenza virus

Exposure of poultry to migratory waterfowl and the international movement of poultry, poultry equipment and people pose risks for introducing avian influenza. Once introduced, the disease can spread from bird to bird by direct contact. Avian influenza viruses can also spread by manure, equipment, vehicles, egg flats, crates and clothing or shoes that have come in contact with the virus. Avian influenza viruses can remain viable at moderate temperatures for long periods and can survive indefinitely in frozen material. One gram of contaminated manure can contain enough virus to infect 1 million birds.

Biosecurity Measures on the Farm

• Protect poultry flocks from coming into contact with wild or migratory birds. Keep poultry away from any source of water that may have been contaminated by wild birds.
• Permit only essential workers and vehicles to enter the farm.
• Provide clean clothing and disinfection facilities for employees
• Thoroughly clean and disinfect equipment and vehicles from other farms
• Avoid visiting poultry farms. If you do visit another farm or live-bird market, change footwear and clothing before returning to your own flock.
• Do not bring birds from slaughter channels, especially live-bird markets, back to the farm.

Biosecurity Measures at Live-bird Markets

• Use plastic instead of wooden crates for easier cleaning
• Keep scales and floors clean of manure, feathers and other debris
• Clean and disinfect all equipment, crates, and vehicles before returning to the farm.
• Keep incoming poultry separate from unsold birds, especially if birds are from different lots.
• Clean and disinfect marketplace after every day of sale.
• Do not return unsold birds to the farm.
