(2) The Secretary of State must, if she authorises a veterinary inspector or another veterinary surgeon to take samples from poultry or other captive birds on other premises or other than for the purposes of such a veterinary inquiry, direct (by notice to the occupier of the premises) whether any of the requirements set out in Schedule 1 apply to the premises where the samples are taken.
