Compartments for protection against avian influenza and Newcastle disease in poultry breeding companies in Great Britain
Department for Environment, Food and Rural Affairs May 2012
OIE Terrestrial Animal Health Code, 2011 edition, Article 4.4.1.
“Compartment means an animal subpopulation contained in one or more establishments under a common biosecurity management system with a distinct health status with respect to specific diseases for which required surveillance, control and biosecurity measures have been applied for the purpose of international trade”
EU Council Directive 2005/94/EC, Article 2. 11.
“’Poultry compartment’ or ‘other captive birds compartment’ means a holding or holdings under a common biosecurity management system containing a poultry or other captive birds sub-population with a distinct health status with respect to avian influenza subjected to appropriate surveillance, control and biosecurity measures”.
Summary of Rules for a Poultry Breeding Compartment
- Part 1 General Conditions
- These rules comply with the compartment rules of the OIE, as laid down in the OIE Terrestrial Animal Health Code (2011 edition), chapters 4.3. and 4.4.
- These rules also comply with the EU Commission Regulation 616/2009, laying down conditions for the approval of compartments for poultry with respect to avian influenza. However they add some specific instruction and detail to those rules, and are therefore referred to as the ‘GB Enhanced Standard’
- The company applying for approval as a compartment in Great Britain (‘The Company’) must have an administrative headquarters located in Great Britain (GB).
- All the flock farm and hatchery premises to be included in the compartment must be located in GB.
- All the premises to be included in the compartment must be under the full management control of the Company. The premises must either be under the direct ownership of the Company, or subject to a detailed management contract giving the Company full control of the premises and the staff working there.
- At the time of application the Company must provide its own Hazard Analysis and Critical Control Point (HACCP) assessment for its operations. The Company must also provide its own detailed biosecurity plan, and an organogram showing the relationship of all the premises for which it is seeking compartment status.
- The Company must have been carrying out specific protection and surveillance for avian influenza in each of the premises in the proposed compartment for at least 6 months prior to applying for approval.
- Prior to inspection by the Veterinary Laboratories Agency (VLA), acting as the authorised agent of Defra, the Company must provide its own management protocol documents, as listed in part 2 of this Summary of Rules.
- VLA will be responsible for assessing the Company’s management protocols, and for carrying out site inspections of each individual compartment premises. If the result of these assessments and inspections is satisfactory Defra will issue a certificate to the Company confirming that compartment status for the specified premises is approved by Defra.
- Part 2 Schedules of Structural and Management Requirements in Approved Premises
- The schedules listed below present the minimum structural provisions and management protocol requirements for each subject area. As these subject areas represent the aspects of the company’s operations in which there is the greatest risk of the introduction or spread of AI/ND, they may be considered as critical control points (CCPs).
- In accordance with the OIE Terrestrial Animal Health Code (2011), chapters 4.3. and 4.4., management protocols must be drawn up by the company, working in partnership with the State veterinary authority or its authorised agent.

- Part 3. Structural and Management Provisions
VLA, acting as the authorised agent of Defra, will inspect each premises in the application to confirm that each of these items is satisfactorily provided:
Premises Physical Assessment
- The location must not be adjacent to any other commercial poultry enterprise. If within 400 metres, precautions appropriate to the risk assessment must be provided.
- The location must not be close to any open water which might attract wild waterfowl. If within 400 metres, precautions appropriate to the risk assessment must be provided.
- The location must not be close to any open feed source (zoological garden, landfill site, outdoor pig farm etc) which might attract large numbers of wild birds. There must be no evidence of large gatherings of wild birds on or close to the premises. If within 400 metres, precautions appropriate to the risk assessment must be provided.
- There must be a robust biosecurity fence to control personnel and vehicle access to the biosecure zone containing the bird accommodation.
- Vehicle and personnel entrances to the biosecure zone must be gated and lockable.
- Entry for personnel to the biosecure zone must be possible only through a hygiene barrier where whole-body showering and changing of clothing is obligatory.
- The construction materials of the buildings must be robust, moisture proof, and capable of being disinfected.
- If there is more than one building within the biosecure zone and they are not linked by enclosed passageways, there must be separate hygiene arrangements at the entrance to each of the buildings.
- Each building within the biosecure zone must be furnished with a concrete apron, specifically covering the working entrance and exit of each building, and the walking areas between buildings.
Staff And Visitors
