Bird flu crisis hits US farms - Urgent biosecurity measures needed

USAgNet - 04/23/2024

The US agriculture sector is facing a significant challenge with the spread of highly pathogenic avian influenza, commonly known as bird flu. In recent weeks, this virus has not only devastated poultry but also shown the capability to infect dairy cows and, on rare occasions, humans. As a result, the U.S. Department of Agriculture (USDA) estimates that around 8.7 million birds have been culled in the past month alone to control the virus's spread.

David Marks, a biologist with the USDA, expressed concern at the Midwest Poultry Federation's trade show about the unusual findings of the virus in various small birds and mammals. These species typically inhabit barns and could easily become vectors for transmitting the virus across different animal populations.

The implications of this are vast, with public health experts like Dr. Jeremy Farrar of the World Health Organization warning that the virus could potentially evolve to more readily infect humans. Farmers are now advised to eliminate standing water and secure food sources to deter wild birds. Some have even resorted to innovative methods like using lasers or covering ponds with mesh to prevent migratory geese from landing.

Further, farmers must inspect and reinforce farm structures to prevent wildlife from entering. Sealing gaps and covering waste bins can significantly reduce the risk of disease spread. The situation demands a robust response to ensure the safety of both agricultural outputs and public health.
