When the deadly H5N1 bird flu virus made its first appearance at a U.S. poultry farm in February 2022, roughly 29,000 turkeys at an Indiana facility were sacrificed in an attempt to avert a larger outbreak.
It didn’t work. Three years later, highly pathogenic avian influenza has spread to all 50 states. The number of commercial birds that have died or been killed exceeds 166 million and the price of eggs is at an all-time high.
Poultry producers, infectious disease experts and government officials now concede that H5N1 is likely here to stay. That recognition is prompting some of them to question whether the long-standing practice of culling every single bird on an infected farm is sustainable over the long-term.
