OIE update on zoning &
compartmentalisation
SPS Committee 17 October 2007
1
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 …
2
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
3
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.”
4
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
5
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

Chapter 1.3.5.
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

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.

implement compartments
