Article 22 Change of collective BVD status by an approved veterinary surgeonI1

further action or investigation has been carried out to confirm the presence of BVDV in any animal forming part of the herd, and

as a result of such action or investigation, either the presence of BVDV has not been confirmed in any such animal or, in the case where the presence of BVDV has been confirmed in any such animal, that animal has been removed from the herd and, prior to its removal, the animal was isolated or other appropriate steps were taken so as to minimise the risk of spread of BVDV to any other animal in the herd.
