Two new cases of highly pathogenic avian influenza (HPAI) were confirmed in a table egg producer and a flock of duck breeders in California, as well as a flock of gamebirds in South Dakota. HPAI was also reported in commercial poultry flocks located in the Manitoba and Saskatchewan provinces in Canada.

According to the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), HPAI affected an independent table egg producer flock of 43,000 birds in Del Norte county and 12,000 birds in a commercial duck breeder flock in Monterey. Both cases are in California.
Both counties have been quarantined to prevent the further spread of avian influenza, the California Department of Food & Ag reported.
In 2022, HPAI in commercial poultry has been confirmed in the following California counties: Butte, Calaveras, Contra Costa, El Dorado, Fresno, Sacramento and Tuolumne.
