Definitions:

The “biosecure zone” is the area at the core of the compartment premises to which high biosecurity standards apply. All personnel must undergo a whole body shower and change of clothing prior to entering the biosecure zone. There must be a biosecurity fence which defines the limits of the biosecure zone. The external walls of buildings may constitute part of the biosecurity fence.

The “compartment premises” means everything contained within the perimeter or boundary which is owned or leased by the company. At the core of the compartment premises is the biosecure zone. On the compartment premises but outside the biosecure zone there will be other, non-biosecure facilities such as a manager‟s house, staff car park, vehicle wheel decontamination pad, etc.

The “company” means the company making the application for compartment status.

The “External Operator” means an independent rodent control company which has a contract with the company to carry out rodent control on the compartment premises (Schedule 17).

“Heightened Risk Period” means any time when an outbreak of avian influenza or Newcastle disease has been confirmed within Great Britain; or when the flock farm falls within an EU protection, surveillance or restriction zone (Schedule 13).

(Note that, regardless of compartment status, all premises will remain subject to general disease control regulations under national and EU legislation).
“Multi-age” means a premises at which there is no period during which the entire premises is totally depopulated. It does not refer to a premises where the birds are of different ages, but it is run on a „staged-in, all-out‟ basis (Schedule 9).

“Multi-building approved premises” means a premises at which there is more than one bird shed, together with other essential buildings such as a shower block or a bedding material store, within the biosecure zone and they are not connected by fully enclosed passageways. Consequently staff must walk in the open air to get from one building to another within the biosecure zone (Schedule 3).

The “producer” means the enterprise producing and supplying the feed, bedding material, or other inputs (Schedules 6, 7, and 8).

“Visitor” means any person who enters a premises who is not employed by the company to work at those premises as their principal work location.

Note this means that a company employee whose principal work location is elsewhere is therefore defined as a visitor and must sign the visitor record accordingly (Schedule 2).

Schedules

In all of the following schedules the Company must ensure that the listed structural requirements are met, and the company‟s written management Protocols contain all of the listed provisions.

NOTE: The paragraphs in bold type apply only to the GB Enhanced Standard. Paragraphs in plain type apply to both the EU Standard and the GB Enhanced Standard.

1. Location and Physical Features of the Compartment Premises

A. Structural Features

1.1  There should be no features within 400 metres of the compartment premises which might attract large numbers of wild birds or waterfowl. Typical attractions would be open water, canals or rivers, free range poultry or hobby bird collections, zoological gardens, outdoor pig farms, landfill sites, rubbish tips, etc.

1.2  The “compartment premises” means everything contained within the perimeter or boundary which is owned or leased by the company. There should preferably be a „perimeter fence‟ to define the limits of the compartment premises.

1.3  The biosecure zone must be enclosed by a „biosecurity fence‟ through which vehicles and personnel may not pass without undergoing appropriate decontamination.

1.4  The “biosecurity fence” has the purpose of preventing access by vehicles, or entry by casual or curious visitors, to the biosecure zone.

The vehicle and personnel gates through the biosecurity fence must be at least to the same standard as the fence itself. The vehicle and personnel gates must be locked. There must be notices clearly stating that access is prohibited except with specific authorisation.

The fence must be at least 4 feet (120 cm) high. If less than 5 feet (150 cm) high there must be at least one strand of tensioned barbed wire along the top of the fence. The fence must be constructed of materials that prevent people from climbing through it. If there are local features which indicate the possible presence of wild waterfowl, the bottom 2 feet (60 cms) must present a barrier that will prevent the waterfowl from walking through.

Notices must be clearly visible at appropriate intervals along the fence stating that people must not enter without specific authorisation.

1.5  In some circumstances it is possible for part of the external walls of buildings such as bird sheds or the shower block to form part of the biosecurity fence. The part of the wall acting as the biosecurity fence must meet the following conditions:

•  The junctions of the biosecurity fence and the wall must be securely tied in, without any gap that people might squeeze through.

•  All ventilation openings in the walls must be adequately protected with structures designed to prevent wild bird access.

•  All doors in the walls must be locked, and capable of being opened only from the inside (as emergency exits).

•  The structure of the walls must be sound, and free from any gaps or faults through which pests could gain access.

•  Trees, bushes and wild vegetation must be cut back from the walls to create a margin of at least 2 metres wide.

1.6  All buildings within the biosecure zone must be constructed of materials that are robust, moisture proof, and capable of being disinfected.

1.7  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 the buildings.

1.8  All ventilation openings on buildings within the biosecure zone must be protected by structures designed to prevent the entry of wild birds.

B. Management Protocols

1.9  At compartment premises where the management has identified the presence of features in the vicinity that are likely to attract unusual numbers of wild birds or waterfowl, the management must produce a risk assessment and a management protocol to reduce the risk in a way that is appropriate to the risk assessment.

1.10  Where such attractants have been identified in the environs, management protocols must specify additional measures to ensure that faecal contamination does not persist on the ground within the biosecure zone where it might present a risk, e.g. frequency of visual checks and use of hoses to clear contamination from concrete aprons around entrances, exits and walkways.

1.11  Regardless of whether or not local bird attractants are present in the environs, management protocols must contain instructions to ensure that there are no attractants within the compartment premises, e.g. spilled bird feed, exposed dead carcases or broken eggs, etc.

5.2  If the introduced birds are subject to quarantine, this may be carried out on an approved premises provided that:
Either the premises is free from any other birds during the quarantine period;
Or the birds already in residence become subject to the same quarantine rules for the same period of time as the introduced birds. The quarantine period will commence when the first introduced bird is placed in the quarantine premises. No bird may be removed from the quarantine premises until the quarantine period has been completed in accordance with paragraph 5.12 below (except for carcases for submission to an AHVLA laboratory).

5.5.2. Or, in the case of a flock farm in a GB Enhanced Compartment, the birds have been derived from an approved premises within another GB Enhanced Compartment;

5.5.3. Or, in the case of a flock farm in a GB Enhanced Compartment, the birds have been derived from an approved premises within an approved Compartment in another country, AND the conditions of approval in that other country have been deemed by the AHVLA Poultry Compartment Project Manager to be fully equivalent to the conditions of the GB Enhanced Compartment scheme;

5.5.4. Or, in the case of a flock farm in a Compartment within the UK which has been approved only under the EU Regulation 616/2009 but not under the GB Enhanced Scheme, the birds have been derived from a flock farm which is an approved premises within another Compartment approved under the EU Regulation in either the UK or another EU Member State. In this case the birds must be kept isolated from all other birds on their new premises for 21 days after arrival, and must be tested for AI as in paragraphs 5.10. and 5.11. below;

5.5.5. Or they undergo the quarantine arrangements described in paragraphs 5.6 to 5.12 below.

Notes to paragraph 5.5.:
a. re 5.5.2. Within the UK all Compartments approved under the GB Enhanced Scheme are considered to be of an equal health standard.
b. re 5.5.3. This paragraph could enable a GB Enhanced Compartment to admit birds for example from the Republic of Ireland, France, Germany or the USA.
c. Paragraph 5.5.4. is consistent with the EU Regulation 616/2009, which states in Annex Part 3. 2. (b): Poultry and their eggs “entering any holding on the Compartment must come from a holding having the same health status as regards avian influenza and/or be checked to ensure that they present no risk of introduction of avian influenza.”

5.6  QUARANTINE ARRANGEMENTS: the following paragraphs apply only to birds introduced from a source outside this Compartment which do not satisfy any of the conditions in paragraphs 5.5.1. to 5.5.4. above. Such birds must undergo quarantine before they can be accepted as belonging to this Compartment.
Before the introduced birds are placed in quarantine the Compartment management must produce written procedures covering paragraphs 5.7. to 5.12. below, and obtain written confirmation from the AHVLA Poultry Compartment Project Manager that they are acceptable.

5.7  Risk assessment by the importing Compartment to demonstrate that there is no possible risk of introduction of infection by the externally sourced birds.

5.8  Procedure for ensuring that the source is disease free: testing of the flocks of origin prior to delivery, independently verified biosecurity standards, etc.

5.10  Laboratory tests to be carried out during the quarantine period to demonstrate the freedom of the birds from AI viruses. An appropriate procedure would be serology or virology at least 7 days after arrival in accordance with Commission Regulation 798/2008 (Annexes III and VIII) (as amended).

For Newcastle disease there must be EITHER similar testing carried out on the birds, OR the parent flocks and the chicks must be vaccinated for ND.

5.11  Procedure for testing of birds which die during quarantine: If clinical observations during quarantine present any suspicion of AI or ND

infection virology must be carried out on dead or diseased chicks in accordance with Commission Regulation 798/2008 (as amended), and as required under UK notifiable disease legislation (Animal Health Act 1981 as amended).

5.12 Procedure to define the completion of quarantine and acceptance of the birds into the compartment. The minimum requirement is full 21 days quarantine commencing from the date when the last externally sourced bird was introduced, plus negative clinical findings and negative virology or serology results before release.

6. Feed Supply to the Compartment Premises

Management Protocols for Laboratory Testing

Part I. Avian Influenza

12.1  Routine serology must be carried out on each compartment approved premises at least once every 6 months.
20 birds must be taken at random on the premises.
The samples must be submitted to the national reference laboratory (VLA). The type of serological test is to be decided by VLA.

This conforms to EU Regulation 616/2009.

12.2  In addition to satisfy the „GB enhanced standard‟ the compartment will carry out extra serological testing either using VLA or a laboratory accredited for avian influenza serology testing under ISO 17025.
The recommended statistical basis of sampling is 95%confidence/25%prevalence. This would indicate a maximum sample size of 11 birds per airspace. (Note that these figures apply to birds kept in a free-mixing barn floor system on the basis that the virus is likely to spread very rapidly; higher statistical standards are necessary for birds kept in cages).

12.3  Frequency of sampling (GB enhanced standard):
Rearing flocks must be sampled at least once within 28 days prior to the start of lay.

Flocks in lay (each airspace) must be sampled at intervals of no longer than 28 days (on the basis that this corresponds to the incubation period plus a few days in the egg store).

12.4  Procedures for resolving inconclusive results: samples referred to VLA. (Inconclusive results referred to VLA, and reported by VLA as negative, can be regarded as confirmed negative and recorded as such).

Part II. Newcastle Disease

12.5  Describe vaccination schedule: frequency of vaccination, type of vaccine, route of administration.

12.6  If the company carries out sampling to confirm the desired immune response, provide details (this sampling is not obligatory).

12.7  If the flocks are not vaccinated, provide serology details similar to Avian Influenza.

13. Heightened Risk Periods
Management Protocols for Additional Precautions

13.1  Visitors: If an HPAI outbreak has occurred within 50 kms of the premises within the past 3 months, all visitors should be prohibited, except those that are essential for the welfare or survival of the birds. Routine maintenance by outside personnel must be suspended. However the visit ban shall not apply to official visits by officers of the veterinary authorities for the purposes of disease control or other statutory functions.

13.2  Vehicles: If an HPAI outbreak has occurred within 50 kms of the premises within the past 3 months, all vehicle entry to the compartment premises should be prohibited, except in cases of exceptional and urgent need. Company vehicles which need to visit the premises, e.g. for egg collection, should be routed through areas well away from the suspect or infected zones. Vehicle decontamination procedures should be reviewed and if necessary increased.

13.3  Feed Delivery: : If an HPAI outbreak has occurred within 50 kms of the premises within the past 3 months, arrangements should be made with the feed company so that lorries are disinfected off site, and visit the compartment premises first before any other deliveries.

Apply additional vehicle decontamination prior to entry to the compartment premises, as above.

13.4  Staff and Equipment Movements between separate Compartment premises : If an HPAI outbreak has occurred within 50 kms of the premises within the past 3 months, all movements to be banned except where absolutely necessary. Separate premises to be treated as far as possible as isolated units.

13.5  Laboratory testing: frequency of serology in laying flocks to be increased at least to the level required in EU Regulation 616/2009, namely:
i. If HPAI has been confirmed in GB within the past 6 months, do serology on 20 birds per compartment premises at least every 3 months.
ii. If the compartment premises falls within an area under movement controls according to EU legislation, do serology within one week of the outbreak and every 21 days thereafter on at least 20 birds per premises, plus virology on 20 tracheal/oropharyngeal swabs and 20 cloacal swabs at the same timing and frequency, plus virology on 5 sick or dead birds (if present) at the same timing and frequency, plus clinical surveillance to be enhanced.

13.6  AND, in addition to the above the GB enhanced standard requires that: If the outbreak of HPAI has been confirmed within 50 kms of the compartment premises within the past 3 months, increase serology to 20 birds per airspace per week.

13.7  Risk Assessment to the whole Compartment: in the case of compartments comprising more than one approved premises, the entire structure of the compartment must be reviewed to assess increased levels of risk to other approved premises within it, and appropriate measures taken.

13.8  Instructions for compartment manager to confirm to Defra in writing at least every 14 days that the above procedures have been being carried out, and that all laboratory test results have been negative. To be sent either by post to Poultry Section, Animal Health, Hadrian House, Wavell Drive, Carlisle CA1 2TB, or by email to LiveAnimalExports.Carlisle@animalhealth.gsi.gov.uk
