Dr. Charles Hatcher, the Tennessee State Veterinarian confirmed on Thursday 9th March that a flock of chickens at a commercial poultry breeding operation tested positive for low pathogenic avian influenza (LPAI).
This chicken breeding operation is located in Giles County, TN. This case is not related to the previous diagnosis of North American Lineage H7N9 HPAI isolated from a broiler breeder contract farm in Lincoln County on March 3rd.
On March 6th, routine screening tests at the Giles County premises indicated the presence of avian influenza in the flock. State and Federal laboratories confirmed the identity of the H7N9 LPAI derived from samples.
Dr. Hatcher noted “When routine testing showed a problem at this facility, the operators immediately took action and notified our lab. That fast response is critical to stopping the spread of this virus.” As a precaution, the affected flock was depopulated and has been buried. The farm is under quarantine.
Domesticated poultry within a 6 mile radius of the index farm are also under quarantine and are under surveillance for the presence of virus. To date no samples have tested positive for avian influenza and no other flocks within the area have shown signs of illness.
The USDA National Veterinary Services Laboratories confirms the H7N9 virus that affected the Lincoln County premises is of North American wild bird lineage. It is not the same as the H7N9 virus affecting China since it is genetically different Neither LPAI nor HPAI pose a risk to the food supply. No affected animals have entered the food chain.
