L 068 2002 EN 37 1 01 20020313 EN 0009.0003 42 1 42 1 <TI> <P>ANNEX III</P> </TI> <TI> <P>PART I</P> </TI> <STI> <P>PROCEDURES FOR THE CLINICAL EXAMINATION OF PIGS</P> </STI>

The clinical examination must be in accordance with the following procedures:

(a) a check of the production and health records of the holding must be carried out, if these records are available; (b) an inspection in all premises of the holding must be carried out; (c) the clinical examination must be carried out in all premises in which the pigs to be moved are kept; (d) it must include the taking of body temperature. The minimum number of the pigs to be checked must allow for the detection of fever if it occurs at a prevalence of 20 % with 95 % confidence in the premise where the pigs to be moved are kept. However, in case of breeding sows or boars, the minimum number of pigs to be checked must allow for the detection of fever if it occurs at a prevalence of 5 % with 95 % confidence in the premise where the pigs to be moved are kept. The checking of temperature must primarily concern the following pigs or group of pigs:

sick or anorexic pigs,

pigs recently recovered from disease,

pigs recently introduced in the holding or for which any contact with a potential source of classical swine fever virus has been identified,

pigs already sampled and serologically tested for classical swine fever, in case the results of these tests do not allow to rule out classical swine fever.

<TI> <P>PART II</P> </TI> <STI> <P>PROCEDURES FOR THE SAMPLING AND TESTING OF PIGS AT SLAUGHTER</P> </STI>

Blood samples for serological tests or blood or tonsils samples for virological tests must be taken from the pigs proceeding from each premise of the holding from which they have been moved.

The minimum number of samples to be taken must allow for the detection of 10 % seroprevalence or virus prevalence with 95 % confidence in each premise.

The type of samples to be taken and the test to be used will be in accordance with the instructions of the competent authority, which will take into account the range of tests that can be performed, the sensitivity of these tests and the epidemiological situation.

In case clinical signs or post-mortem lesions suggesting classical swine fever are detected when the pigs are slaughtered or killed, the competent authority shall ensure that further appropriate sampling and virological testing are immediately carried out.
