A second outbreak of bird flu has been detected in Tennessee. The state veterinarian confirms that a flock of chickens at a commercial poultry breeding operation in Giles County has tested positive for low pathogenic avian influenza (LPAI). The company that operates it is a different company from the one associated with the recent detection of highly pathogenic avian influenza (HPAI) in Lincoln County. At this time, officials do not believe one premises sickened the other. On March 6, routine screening tests at the Giles County premises indicated the presence of avian influenza in the flock. State and federal laboratories confirmed the existence of H7N9 LPAI in tested samples. As a precaution, the affected flock was depopulated and has been buried. The premises is under quarantine. Domesticated poultry within a 10 kilometer (6.2 mile) radius of the site are also under quarantine and are being tested and monitored for illness. To date, all additional samples have tested negative for avian influenza and no other flocks within the area have shown signs of illness. The Giles County LPAI incident is similar to the Lincoln County HPAI incident in that both the low pathogenic and highly pathogenic viruses are an H7N9 strain of avian influenza. USDA’s 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 China H7N9 virus affecting Asia and is genetically distinct.
