ANNEX II U.K. Principles and procedures for cleansing and disinfection

1. General principles and procedures: U.K.

(a)

the cleansing and disinfection operations and where necessary the measures to destroy rodents and insects are carried out under official supervision and in accordance with the instructions given by the official veterinarian;

(b)

the disinfectants to be used and their concentrations are officially approved by the competent authority to ensure destruction of classical swine fever virus;

(c)

the activity of disinfectants is to be checked before use, as activity of certain disinfectants is diminished by prolonged storage;

(d)

the choice of disinfectants and of procedures for disinfection is to be made taking into account the nature of the premises, vehicles and objects which are to be treated;

(e)

the conditions under which degreasing agents and disinfectants are used must ensure that their efficacy is not impaired. In particular technical parameters provided by the manufacturer, such as pressure, minimum temperature and required contact time, are to be observed;

(f)

irrespective of the disinfectant used, the following general rules are to apply:

• thorough soaking of bedding and litter as well as faecal matter with the disinfectant,

• washing and cleaning by careful brushing and scrubbing of the ground, floors, ramps and walls after the removal or dismantling, where possible, of equipment or installations so as to avoid impairing the cleansing and disinfection procedures,

• then, further application of disinfectant for a minimum contact time as stipulated in the manufacturer's recommendations,

• the water used for cleaning operations is to be disposed of in such a way as to avoid any risk of spreading the virus and in accordance with the instructions of the official veterinarian;

(g)

where washing is carried out with liquids applied under pressure, re-contamination of the previously cleansed parts is to be avoided;

(h)

washing, disinfecting or destroying of equipment, installations, articles or compartments likely to be contaminated is to be carried out;

(i)

following the disinfection procedures, re-contamination is to be avoided;

(j)

cleansing and disinfection required in the framework of this Directive is to be documented in the holding or vehicle register and, where official approval is required, be certified by the supervising official veterinarian.

2. Special provisions on cleansing and disinfection of infected holdings: U.K.

(a)

preliminary cleansing and disinfection:

• during the killing of the animals all necessary measures are to be taken to avoid or minimise the dispersion of classical swine fever virus. This is to include inter alia the installation of temporary disinfection equipment, supply of protective clothing, showers, decontamination of used equipment, instruments and facilities and the interruption of power supply to the ventilation,

• carcases of killed animals are to be sprayed with disinfectant,

• if the carcases must be removed from the holding for processing, covered and leak proof containers are to be used,

• as soon as the carcases of the pigs have been removed for processing, those parts of the holding in which these animals were housed and any parts of other buildings, yards, etc. contaminated during killing, slaughter or post-mortem examination are to be sprayed with disinfectants approved for use in accordance with Article 12,

• any tissue or blood which may have been spilled during slaughter or post-mortem or gross contamination of buildings, yards, utensils, etc., is to be carefully collected and processed with the carcases,

• the disinfectant used is to remain on the treated surface for at least 24 hours;

(b)

final cleansing and disinfection:

• manure and used bedding are to be removed and treated in accordance with point (3)(a),

• grease and dirt are to be removed from all surfaces by the application of a degreasing agent and the surfaces washed with water,

• after washing with water, further spraying with disinfectant is to be carried out,

• after seven days the premises are to be treated with a degreasing agent, rinsed with water, sprayed with disinfectant and rinsed again with water.

3. Disinfection of contaminated bedding, manure and slurry: U.K.

(a)

manure and used bedding are to be stacked to heat, sprayed with disinfectant and left for at least 42 days or destroyed by burning or burying;

(b)

slurry is to be stored for at least 42 days after the last addition of infective material, unless the competent authorities authorise a reduced storage period for slurry which was actually treated in accordance with the instructions given by the official veterinarian so as to ensure the destruction of the virus.

4. However, by way of derogation from points 1 and 2, in case of open-air holdings, the competent authority may establish specific procedures for cleaning and disinfection, taking into account the type of holding and the climatic conditions. U.K.
