A strain of highly pathogenic avian influenza is currently infecting and killing wild birds and domestic birds in at least 29 states across the United States.

A UC Agriculture and Natural Resources poultry expert urges commercial and backyard chicken owners to take precautions.

“When it comes to protecting your flock, there is no treatment for HPAI so the best thing you can do is focus on biosecurity,” said Maurice Pitesky, UC Cooperative Extension poultry specialist in the School of Veterinary Medicine at UC Davis. 

“In order to protect our commercial and backyard chickens, it is essential for all of us who own poultry to do our part,” he said.

The current avian influenza outbreak is already considered the worst bird flu outbreak since the 2015 HPAI outbreak when nearly 50 million poultry were euthanized or died.

The HPAI virus is being spread by migrating birds and California is part of the Pacific migratory flyway.

“Waterfowl migrate thousands of miles between wintering and breeding locations and have long been known to be the natural reservoirs for avian influenza viruses, which are associated with high mortality in poultry,” Pitesky explained. “Many of these migrating ducks, geese and swans winter in the relatively warmer climate of California's Central Valley among other locations where they can find appropriate habitat.” 

Prevent exposure

Pitesky recommends preventing chickens and other poultry from exposure to waterfowl and other potential wild bird carriers.

“At the most generic level, that means making sure your birds are separated from any wildlife,” he said. “Whether you have a million-bird farm or just a few backyard chickens, the message is the same: maintain the best biosecurity you can, which includes fencing and make sure you reduce reasons for waterfowl to come near your birds such as spilled feed and ponding of water.

“Our previous research has shown that waterfowl are attracted to both natural and human-made wetlands and lagoons. So, if you live near one of these types of habitats, your biosecurity efforts are even more important.”

The HPAI virus does not currently affect humans. Pitesky said it is important to recognize that avian influenza viruses, like all viruses, can mutate or recombine to form new versions of virus that may affect humans.
