The U.S. Department of Agriculture confirmed the presence of H7 avian influenza in a commercial chicken breeder flock in Lincoln County, Tenn. This is the first case of the virus on U.S. soil in 2017. USDA and the Tennessee Department of Agriculture will cull the 73,500 birds on the affected farm. In addition, the Tennessee Department of Agriculture established a 6.2-mile quarantine zone, which will affect about 30 other poultry farms.

Tyson Foods confirmed the affected farm is contracted to the company. Tyson is working with Tennessee and federal officials to contain the virus by euthanizing the birds on the contract farm, and does not expect disruptions to its chicken business.
