Division 2.2.2.2 Sampling as part of official controls

Routine sampling shall be performed as described in point 2.2.2.1.

Confirmatory sampling following the detection of the relevant Salmonella serotypes from sampling at the hatchery shall be performed as described in point 2.2.2.1.

Additional samples can be collected for the possible testing of antimicrobials or bacterial growth inhibitors as follows: birds shall be taken at random from within each poultry house of birds on the holding, normally up to five birds per house, unless the competent authority deems it necessary to sample a higher number of birds.

If the source of infection is not confirmed, antimicrobial testing shall be carried out or new bacteriological testing for the presence of the relevant Salmonella serotypes shall be carried out on the breeding flock or their progeny before trade restrictions are lifted.

If antimicrobials or bacterial growth inhibitors are detected, the Salmonella infection shall be considered as confirmed.

Suspicion of false results

In exceptional cases where the competent authority has reason to question the results of the testing (such as false positive or false negative results), it may decide to repeat the testing in accordance with point (b).
