The U.S. has lost about 52.7 million birds to highly pathogenic H5N1 avian influenza since February 2022, across 46 states. It is the worst U.S. poultry health disaster since 2014-2015 and the outbreak has persisted through summer and resurged.
Large losses of layers and broilers reduce poultry supply and feed demand, and egg supply tightness supports higher prices. The scale of the outbreak makes this a meaningful driver for poultry and feed markets.
