OIE update on zoning & compartmentalisation Dr Sarah Kahn Head, International Trade Department OIE update on zoning & compartmentalisation SPS Committee 17 October 2007 Comments (with copyright) / Commentaires (soumis au Copyright) :

OIE definitions in Ch.1.1.1 Zone/Region Compartment a clearly defined part of a country containing an animal subpopulation with a distinct health status … Compartment one or more establishments (premises in which animals are kept) under a common biosecurity management system containing an animal subpopulation with a distinct health status …

History of Chapter 1.3.5. Chapter on Zoning and Regionalisation in Section on Import Risk Analysis - 1993 concepts of zone and compartment need for concrete steps to apply concepts Revisions adopted in 2005 & 2007

Rationale “Given the difficulty of establishing and maintaining a disease free status for an entire country, especially for diseases the entry of which is difficult to control through measures at national boundaries, there may be benefits …to establishing and maintaining a subpopulation with a distinct health status within its territory.”

Objectives zoning and compartmentalisation are procedures implemented by a country to define subpopulations of distinct animal health status within its territory for the purpose of disease control and/or international trade

In practice… A zone is defined primarily on a geographical basis (using natural, artificial or legal boundaries) A compartment is defined primarily by management and husbandry practices relating to biosecurity Responsibility for both approaches is with the Veterinary Authority of the country concerned
