Highly pathogenic H7 avian influenza has been confirmed in a commercial chicken breeder flock in Lincoln County, Tennessee, according to the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service. It is the first confirmed case of avian influenza in commercial poultry in the United States this year. The flock of 73,500 birds is located within the Mississippi flyway.
A commercial chicken-breeding operation has tested positive for low-pathogenic avian influenza in Giles County, Tennessee. The company that manages the operation is different from the one associated with the recent detection of highly-pathogenic avian influenza in Lincoln County, Tennessee. Officials do not believe poultry from one premises sickened the other.
MADISON, Wis. – Animal-health officials with the Wisconsin Department of Agriculture, Trade and Consumer Protection are urging all poultry owners, regardless of size, to increase biosecurity efforts now that two strains of avian influenza have been found in the Mississippi flyway. The concern comes after a highly-pathogenic H7 strain was found in a Tennessee commercial chicken flock and a low-pathogenic H5 strain was found in a Wisconsin commercial turkey flock.
