12.—(1) Notwithstanding the prohibition on slaughter of an animal or batch of animals by notice given in accordance with regulation 22(4), that animal or batch of animals may be slaughtered before the withdrawal of such notice if the owner of that animal or batch of animals complies with the following paragraphs of this regulation.
(2) Notice of the proposed date and place of slaughter must be given to an authorised officer before that date.
(3) The animal or batch of animals, marked, or caused to be marked, by an authorised officer under regulation 21(2)(c), must be accompanied to the place of slaughter by a certificate issued by an authorised officer identifying the animal or batch of animals and the farm of origin.
(4) After slaughter any animal product derived from the animal or from an animal of that batch of animals must be retained in such place and manner as an authorised officer may specify, while it is subjected to such examination as an authorised officer may reasonably consider necessary.
(5) Where the examination (the result of which is to be given by an authorised officer to the owner by notice in writing) confirms that any animal product referred to in paragraph (4) contains an authorised substance at a concentration exceeding the relevant maximum residue limit, the animal product must be disposed of for a purpose other than human consumption.
