Avian influenza H5N1 clade 2.3.4.4b has circulated in wild birds in Europe, Asia and Africa since at least 2020 and reached North America in late 2021. The virus caused unusually high mortality in endangered South American seabirds and marine mammals starting in early 2023.
This is background on the virus's wildlife spread rather than a new supply shock, so it has little direct effect on feed or meat prices.
