Council Directive 80/217/EEC of 22 January 1980 introducing Community measures for the control of classical swine fever · European Union

Virus isolation is required in cases of inconclusive or negative results from material derived from animals giving rise to suspicion of swine fever or with material from holdings which have had contact with cases of swine fever. Where, in such circumstances, the demonstration of viral antigen or virus isolation has not been successful, tests for the detection of neutralizing antibody shall be applied to blood samples of animals which have recovered from the suspect disease and from those known to have been in contact with the disease.
