Poultry biosecurity risks: identifying flows

Quick facts

  • Define system boundaries around barns and farmsteads and line(s) of separations to separate clean from dirty areas.

  • Be aware of every flow that crosses system boundaries and line(s) of separations.

  • Track each flow such as people, equipment and supplies.

  • Know the risk for each flow and decide which risks you need to manage more carefully first.

  • Create and carry out biosecurity plans to reduce the risks for each flow.

You can outline system boundaries and lines of separation using an aerial photograph.

Farms use biosecurity to:

  • Prevent infectious disease organisms from entering the farm.

  • Control disease spread within and between barns and farms.

Studying flows on your farm is an orderly way to plan how the following move into, through and from the facility.

  • People

  • Birds

  • Feed

  • Supplies

  • Materials

  • Equipment

  • Ventilating air

You can also study flows to assess and maintain your biosecurity and efficiently and safely carry out the operation’s management and operational plans.
