Regulation 13 Powers of entry
Subject to paragraph (2) below, an authorised officer, on producing, if so required, some duly authenticated document showing his authority, may, for the purposes of these Regulations enter premises which he has reasonable cause to believe are used—
for the keeping, rearing, production, sale (whether by private treaty or auction) or slaughter of animals;
for the storage of fresh meat;
for the manufacture, handling, storage, transport, administration, distribution or sale of any transmissible substance.
This power shall be exercisable at any reasonable time, but admission to any private dwellinghouse shall not be demanded as of right unless not less than seven days' notice of the intended entry has been given to the occupier.
An authorised officer entering any premises by virtue of this regulation may take with him such other persons and such equipment as may appear to him to be necessary.
