If a veterinary inspector suspects that poultry on any premises may have been exposed to the risk of a designated disease, that inspector shall serve a notice on the occupier or person in charge of the premises in accordance with this article.

In paragraphs (1) and (2), exposure to the risk of a designated disease or to another disease includes exposure, either directly or indirectly, as a result of the movement of persons, birds, animals or vehicles or in any other way.

On service of a notice under this article, a veterinary inspector may enter premises which are the subject of such notice and use whatever means that inspector thinks suitable to detect the existence of any disease, to count the birds, and to monitor their movements.

On service of a notice under this article, no person shall move any bird or any other thing liable to transmit disease from the premises except under the authority of a licence granted by a veterinary inspector.

A veterinary inspector may limit the measures provided for in a notice served under this article to a part of the premises and to the birds contained within that part of the premises, provided that those birds have been housed, kept and fed completely separately by separate persons.
