USDA-APHIS confirmed highly pathogenic avian influenza H7N9 in commercial breeder flocks in Lincoln County, Tennessee in March 2017, followed by a second infected flock three kilometers away. All affected flocks were depopulated, and the article recaps the 2014-2015 outbreak that destroyed 50 million birds.
Localized US flock losses with depopulation have limited national supply effects, but any export restrictions could affect poultry trade. The impact on feed demand is small unless the outbreak spreads.
