The highly contagious avian flu is being spread primarily by migratory birds, putting game birds, and backyard and commercial poultry at risk.

“Poultry owners should take precautions to prevent their birds from contacting waterfowl or the habitat that waterfowl frequent because this strain of avian influenza is highly contagious,” said Maurice Pitesky, UC Davis School of Veterinary Medicine associate professor of Cooperative Extension.

Infected waterfowl shed the highly pathogenic avian influenza virus in their feces and respiratory secretions, where the virus can remain viable for months in the environment.

“If you can't confine your birds in a coop, focus on good sanitation and reducing contact with waterfowl and their habitat such as agricultural fields and ponds,” he said.

Pitesky urges commercial and backyard chicken owners to monitor their birds for the following symptoms:

  • Reduced egg production

  • Trouble breathing

  • Clear, runny discharge from nose, mouth and eyes

  • Lethargy or lack of energy

  • Loss of appetite

  • Drinking less

  • Swollen eyes, head, wattles or combs

  • Discolored or bruised comb, wattles or legs

  • Sudden death

Focus on biosecurity

To prevent exposure to potentially infected waterfowl, Pitesky suggests reassessing and redoubling biosecurity efforts to prevent contact between wild animals and domestic poultry.

Specifically, he recommends keeping birds away from ponds and other open water where they may contact waterfowl, which are the primary reservoir of the disease. To prevent cross-contamination, use clothing and boots that stay on your property and avoid sharing equipment with other bird owners.

A local veterinarian or UC Cooperative Extension farm adviser may have more suggestions to reduce risk.
