Biosecurity Practices Critical in Protecting Against Avian Influenza

Mar 04, 2026

While it may seem as though wild bird migration has just ended, spring migration will be starting soon. As wild bird movement increases, the threat of highly pathogenic avian influenza (HPAI) across the U.S. will rise.

North Dakota State University Extension experts are urging poultry and dairy owners to review and strengthen their biosecurity plans to reduce the risk of disease transmission on farms and rural properties.

HPAI is a strain of influenza A primarily carried by wild birds. The virus can spread to domestic poultry flocks and, in some cases, dairy cattle. It is shed in feces and respiratory secretions and can survive for extended periods in cool, damp conditions — making spring and fall migration especially high-risk times for animal owners.

“Creating and consistently following a strong biosecurity plan is the best defense poultry and dairy owners have against HPAI,” says Dr. Jake Galbreath, NDSU Extension veterinarian. “Now is the time to evaluate potential risk points on your operation and make improvements before exposure occurs.”

Recent detections of HPAI in poultry and dairy operations across the country highlight the importance of preparedness and early identification.
