Division 4

When the pigs referred to in point 3 are slaughtered or killed, blood samples for serological tests or blood or organ samples such as tonsil, spleen or lymph nodes for virological tests must be taken from pigs proceeding from each of the subunits from which pigs 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 subunit.

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.
