In April 2024, as his first hens tested positive for the highly pathogenic avian influenza H5N1 virus, Herbruck turned to the tried-and-true U.S. Department of Agriculture playbook, the “stamping-out” strategy that helped end the 2014-15 bird flu outbreak, which was the largest in the U.S. until now.
Within 24 to 48 hours of the first detection of the virus, state and federal animal health officials work with farms to cull infected flocks to reduce the risk of transmission. That’s followed by extensive disinfection and months of surveillance and testing to make sure the virus isn’t still lurking somewhere on-site.
Since then, egg farms have had to invest millions of dollars into biosecurity. For instance, employees shower in and shower out, before they start working and after their shifts end, to prevent spreading any virus. But their efforts have not been enough to contain the outbreak that started three years ago. [emphasis added]
