A commercial upland gamebird operation in Kansas is the most recent case of highly pathogenic avian influenza (HPAI) to be reported in the United States.

According to the United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS), HPAI was confirmed an upland gamebird flock in Mitchell County on January 17. There were 6,900 birds in the flock.

This is the second case of 2023 in which a U.S. upland gamebird flock was infected with HPAI. The first case was also in Kansas. On January 4, a flock of 8,900 birds in Anderson County was affected, according to APHIS.

The only other case of HPAI in a commercial flock in Kansas during the 2022-23 outbreak involved a flock of commercial turkey breeders in McPherson County. That case also involved 6,900 birds and was confirmed on April 13, 2022.

None of the other U.S. cases of HPAI to be confirmed to date in 2023 have involved flocks that APHIS identified as commercial flocks.

States that had confirmed HPAI cases in upland gamebird operations in 2022 include California, Colorado, Wisconsin, South Dakota, Nebraska, Idaho, Texas and New York.


Another avian influenza case in Canada

The HPAI outbreak continues to affect commercial poultry flocks in the Canadian province of British Columbia. 

The Canadian Food Inspection Agency (CFIA) reported that HPAI was confirmed in a commercial flock in the municipality of Chilliwack, the 21st case for the locality during the 2022-23 outbreak.

Information concerning the type of birds involved or how many birds were in the flock was not disclosed.
