The United States Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service (APHIS) has confirmed the presence of highly pathogenic avian influenza (HPAI) in a backyard mixed species poultry flock in Franklin County, Kansas and a non-commercial backyard flock (non-poultry) in Mclean County, Illinois.

Samples from the Kansas flock were tested at the Kansas State Veterinary Diagnostic Laboratory and samples from the Illinois flock were tested at the University of Illinois Veterinary Diagnostic Laboratory. Both laboratories are part of the National Animal Health Laboratory Network. The samples were confirmed at the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa.

APHIS is working closely with state animal health officials in both states on joint incident responses. State officials quarantined the affected premises, and birds on the properties will be depopulated to prevent the spread of the disease. Birds from the flocks will not enter the food system.
