Understanding Highly Pathogenic Avian Influenza (HPAI)
HPAI is a highly contagious viral disease that can affect a wide range of bird species, including chickens, turkeys, ducks, and geese. The virus is naturally spread by migratory waterfowl, but can also be transmitted through direct contact with infected birds or contaminated surfaces. USDA APHIS provides thorough information on the disease, its spread, and biosecurity measures.
What Does This Mean for Missouri Poultry Producers?
These recent detections underscore the importance of strict biosecurity protocols for all poultry operations, regardless of size. Producers are urged to review and implement biosecurity measures, including limiting contact with wild birds, controlling access to facilities, and practicing thorough cleaning and disinfection.The Missouri Department of Agriculture is working closely with the USDA to monitor the situation and implement response plans.
