Secure Food Supply Plans
The Secure Food Supply Plans for poultry, milk, pork and beef were developed to aid producers, transporters and food processors in the event of a foreign animal disease outbreak, like High Pathogenicity Avian Influenza (HPAI). These response plans are designed to avoid interruptions in animal/animal product movement from operations with no evidence of infection and maintain business continuity.
