Animal diseases that are known to spread primarily through human activities can be prevented and controlled through the application of biosecurity measures along the production and marketing chain, together with increased awareness and education. With this document, FAO, OIE and the World Bank aim to provide applied biosecurity recommendations to all pork production stakeholders in the numerous pig farming systems worldwide, particularly in developing and transition countries. Pig farmers are the main intended beneficiaries of the paper, but it is also of use to veterinary and technical service providers who are in a position to deliver and implement the proposed measures, to decision-makers in government and to project managers in agricultural development.
