  • USDA. Animal and Plant Health Inspection Service.
    The U.S. Department of Agriculture’s (USDA) Animal and Plant Health Inspection Service is launching a new outreach campaign focused on preventing the spread of infectious poultry diseases in both commercial and backyard poultry. Considering the devastating impact of the highly pathogenic avian influenza outbreak in 2014-2015, as well as this year’s outbreak of virulent Newcastle disease, the timing is right for everyone in the poultry community to work together to protect the health of our nation’s flocks. The “Defend the Flock” campaign to promote biosecurity combines and updates two previous campaigns that were each targeted at a specific segment of the poultry population.
