The most recently reported cases of highly pathogenic avian influenza (HPAI) in North America involve three commercial poultry cases in Canada and one commercial upland gamebird operation in California.

Avian influenza in British Columbia, Ontario

Three more cases of HPAI were reported in commercial poultry flocks in Canada, with two in British Columbia and one in Ontairo.

The Canadian Food Inspection Agency (CFIA) reported that one case of HPAI was confirmed in Abbotsford, British Columbia, on December 22 and one more was confirmed there on the following day. With those two cases, Abbotsford has now had 43 cases of HPAI in 2022, while British Columbia has had 69.

The other case reported by CFIA was in a commercial poultry flock in Lambdon Shores, Ontario, on December 21, a third for that municipality.

CFIA did not offer further information concerning the size of those flocks or the types of birds involved.

Avian influenza in California

On December 22, the presence of HPAI was confirmed in a commercial gamebird operation in Glenn County, California, the first case for that county in 2022, according to information from the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS).


The flock involved approximately 32,000 birds.

So far in 2022, California has had 15 cases of HPAI confirmed in commercial flocks, affecting nearly 760,000 birds.

Since Christmas, neither the CFIA nor APHIS has yet to report any new cases of HPAI.
