Division 8.15.2 When an official veterinarian inspects an identified holding of origin in case the poultry or other captive birds are slaughtered, the following measures must be carried out:

A check of the production and health records of the holding, if such records exist.

A clinical inspection in each production unit, including an evaluation of its clinical history and clinical examinations of poultry or other captive birds taking into account the consultation with the official veterinarian at the slaughterhouse who must provide details of any previous inspection data and results of ante- and post-mortem examinations.

Unless the competent authority is satisfied that the suspected presence of HPAI may be excluded on the basis of the veterinary investigation in accordance with points (a) and (b), the standard samples must be taken from each production unit.

In addition to the standard samples referred to in point (c), samples of at least five sick, dead or slaughtered birds in the slaughterhouse with pathological findings must be submitted for laboratory tests.

Provided that the results of the laboratory tests of the samples referred to in points (c) and (d) are negative and that there is no clinical suspicion of HPAI on the holding of origin and in the slaughterhouse, the official supervision may be lifted.
