The Hub for Biosecurity to Protect the Herd and Flock

Farm biosecurity is the practice of preventing or greatly reducing the introduction of diseases and pests, and is a whole farm approach for assessing, prioritizing and addressing the risks to herd/flock health.

Use this website as a guide and source of current information on how to make biosecurity a routine on the farm, in the backyard, and anywhere farm animals are raised.

What are the risks? Risk can be categorized by source of possible infection (other livestock, visitors, wildlife); area of the farm (maternity pens, facilities for newborns and youngstock, feed storage areas); susceptibility of animals (baby calves, youngstock and animals that just gave birth, all having weaker immune systems).
