# 2003/422/EC: Commission Decision of 26 May 2003 approving an African swine fever diagnostic manual (Text with EEA relevance) (notified under document number C(2003) 1696), Division 2

Extent: E+W+S+N.I.

Sampling must primarily concern:
pigs showing signs or post-mortem lesions suggesting ASF and their in-contact pigs,
other pigs which might have had risky contacts with infected or suspected pigs or which are suspected to have been contaminated with the ASF virus. These pigs must be sampled in accordance with the instructions of the competent authority, which will take into account the epidemiological situation.
Furthermore, pigs proceeding from each of the subunits of the holding must be sampled at random. In this case, the minimum number of samples to be taken for serological tests must allow for the detection of 10 % seroprevalence with 95 % confidence in the subunit in question.
The type of samples to be taken for virological tests 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.
