Monday, more than 73,000 chickens were destroyed due to an outbreak of an H7 strain of highly pathogenic avian influenza at a Tennessee farm. Thirty other farms within a six-mile radius are also being quarantined. Government officials in Hong Kong, Korea and Taiwan all announced bans on the import of poultry from Tennessee as well as from Wisconsin, where low pathogenic H5N8 bird flu was also confirmed. Iowa Poultry and Egg Association Executive Director Kevin Stiles says the outbreak is a concern to his state’s producers who dealt with an outbreak in 2015.

He says Iowa’s producers did a good job of tightening biosecurity following the 2015 AI epidemic and are just now regaining lost markets.

Stiles says the USDA and Tennessee Agriculture Department officials have done a good job of responding to the bird flu outbreak.

Tennessee’s Department of Agriculture says the farm is located in Lincoln County, just west of Chattanooga and the breeder supplies Tyson Food, Incorporated.
