The USDA Animal and Plant Health Inspection Service(APHIS) has confirmed a second case of highly pathogenic H7N9 avian influenza in a commercial breeder flock in Lincoln County, Tennessee. This H7N9 strain detected in the flock of 55,000 chickens is located in the Mississippi flyway, is the same strain of avian influenza that was previously confirmed in Tennessee and is not the same as the China H7N9 virus that has hit Asia.

Samples from the affected flock, which displayed signs of illness and experienced increased mortality, were tested at Tennessee’s Kord Animal Health Diagnostic Laboratory and confirmed at the APHIS National Veterinary Services Laboratories (NVSL) in Ames, Iowa.

USDA is working with the Tennessee Department of Agriculture on the joint incident response. State officials quarantined the affected premises, and depopulation has begun. Federal and State partners will conduct surveillance and testing of commercial and backyard poultry within a 10 kilometer (6.2 mile) radius of the site.

The United States has the strongest AI surveillance program in the world, and USDA works with its partners to actively look for the disease in commercial poultry operations, live bird markets and in migratory wild bird populations.

USDA will be informing the World Organization for Animal Health (OIE) as well as international trading partners of this finding. USDA also continues to communicate with trading partners to encourage adherence to OIE standards and minimize trade impacts.
