USA: LPAI H7N9 in Giles County, Tennessee
As part of routine, pre-slaughter testing and surveillance for H5/H7 Avian Influenza, low pathogenic avian influenza (LPAI) H7N9 of North American wild bird lineage was detected in a commercial grandparent stock primary broiler breeder flock in Giles County. Slight increase in mortality and a slight decrease in egg production. This is the first detection of H7N9 LPAI poultry in TN and also the first detection of LPAI H7N9 in commercial poultry in the United States in 2017. Although this is a low pathogenicity H7 strain, as a precautionary preventive measure, the flock was depopulated.
