Recent developments in the avian influenza outbreak have brought several important issues to light. The Trump administration has shifted its approach to controlling the virus, moving away from mass depopulation of poultry farms in favor of enhanced biosecurity measures and targeted bird medications, as reported by Farm Progress. This marks a significant change in strategy.

The poultry industry is divided on the issue of vaccinations. Egg-laying farms, which have been severely impacted by H5N1, are calling for vaccinations to be part of the national response, while the National Chicken Council opposes vaccination due to concerns over export restrictions. The USDA has conditionally approved a bird flu vaccine, but it remains unclear whether or when it will be used.

In addition, the USDA has confirmed the presence of H5N1 on dairy farms in Nevada and Arizona. This new strain, which has been found in wild birds, raises concerns about the potential spread to dairy operations, especially in areas with a high concentration of poultry farms.

As of 2022, over 754 commercial poultry flocks, affecting 162 million birds, have tested positive for H5N1. Additionally, 972 cases have been reported in dairy cows across 17 states, with new cases appearing in recent weeks.
