The National Swine Farm-Level Biosecurity Standard

1.1 Defining Biosecurity

Biosecurity is the term used to describe the measures and procedures needed to protect a population against the introduction and spread of pathogens. FAO/WB/OIE experts (2009) defined it as “the implementation of measures that reduce the risk of the introduction and spread of disease agents. It requires the adoption of attitudes and behaviours by people to reduce risk in all activities involving domestic, captive/exotic and wild animals and their products”.

A biosecurity plan can be implemented to attain three strategic objectives:

1) Bio-exclusion or external biosecurity: policies developed to prevent the introduction of a new pathogen to pigs housed on livestock premises.

2) Bio-management or internal biosecurity: a biosecurity strategy developed to reduce the spread of disease among pigs on premises already contaminated with a pathogen.

3) Bio-containment: a biosecurity strategy developed to prevent the escape and spread of pathogens already present on pig premises in order to prevent spread to another population of animals.
