New cases of highly pathogenic avian influenza (HPAI) were confirmed in Colorado and South Dakota on December 20.

The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) announced that the presence of the virus was confirmed in a commercial table egg laying operation in Weld County, Colorado, and a commercial meat turkey operation in Hanson County, South Dakota.

The Colorado case involved 260,000 hens, while the South Dakota case involved 31,800 turkeys.

Only one other HPAI case was reported by APHIS on December 20, but that was in a backyard flock of 80 birds in another state, and therefore, it won't have an impact on international poultry trade.

So far in 2022, Colorado has had eight commercial flocks affected by HPAI, involving nearly 6.4 million birds. Weld County, accounts for six of those eight cases with two of them being confirmed within the past week.

South Dakota, meanwhile, has had 61 commercial flocks affected by HPAI this year, with five of those being commercial turkey flocks in Hanson County. Total bird losses for the state in 2022 is approaching 4 million.
