A second commercial turkey flock in Sanpete County, Utah, tested positive for highly pathogenic avian influenza (HPAI).

The United States Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) stated that the virus was confirmed in a flock of 25,900 turkeys there on July 19. That case was confirmed five days after the presence of HPAI was confirmed in another flock in Sanpete County, with 15,500 birds in that flock.

Prior to these two cases in Utah, the last case of HPAI in the United States was confirmed on June 9 in a commercial layer pullet flock in Weld County, Colorado, whereas the last HPAI case in commercial poultry in North America was confirmed on July 9 in La Jacqeues-Cartier, Quebec, Canada.

HPAI has now appeared in three commercial poultry flocks in Utah. The first case was confirmed on April 25, involved a commercial layer flock in Cache County. There were 1.5 million birds in that flock. There have also been four backyard flock infections in Utah, and one infection at a petting zoo/exhibition farm.


So far in 2022, HPAI has been confirmed in commercial poultry in the states of Michigan, Wisconsin, Oklahoma, Minnesota, North Dakota, South Dakota, Nebraska, Kansas, Iowa, Missouri, Kentucky, Indiana, Colorado, North Carolina, Pennsylvania, Delaware, Maryland and Utah. The virus has also been found in commercial game bird operations in Texas, New York and South Dakota.
