Preventing spread of diseases

Biosecurity refers to everything people do to keep diseases – and the viruses, bacteria, funguses, parasites, and other microorganisms that cause diseases – away from birds, property, and people. Biosecurity measures can include keeping visitors to a minimum, changing clothes before entering poultry areas, cleaning tools or equipment before moving them to a new poultry facility, and more.

Anyone involved with poultry production, from a small backyard to a large commercial producer, should review their biosecurity activities to ensure the health of their birds. USDA’s Animal and Plant Health Inspection Services (APHIS) has materials about biosecurity, including videos, checklists, and a toolkit available as part of its  Defend The Flock program .
