OIE update on zoning compartmentalisation SPS
Committee 17 October 2007
2
OIE definitions in Ch.1.1.1

• Zone/Region
• 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

3
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

4
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.

5
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

6
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

• Clarifies the uses and benefits
• Suggests the sequence of steps to be taken in
  defining a zone/compartment
• accurate animal health information
• Negotiation between Veterinary Authorities of
  exporting country and importing country

10
Disease chapters

• The Code makes recommendations for
  zones/compartments for some diseases
• the recommendations depend on
• epidemiology of the disease
• environmental factors
• appropriate and applicable biosecurity measures
• Surveillance essential

NEW OIE Checklist

• Checklist on the Practical Application of
  Compartmentalisation for Avian Influenza and
  Newcastle Disease distributed at the General
  Session in May 2007.
