Food Act 1984

12 (1) Within 60 hours after the sample was procured from the purveyor, he may serve on the authority by whose officer it was procured, or, if it was not procured by an officer of any authority, on the food and drugs authority within whose area it was procured, a notice—

(a) stating the name and address of the seller or consignor from whom he received the milk and the time and place of delivery to himself of milk from a corresponding milking; and

(b) requesting the authority to take immediate steps to procure, as soon as practicable, a sample of milk from a corresponding milking in the course of transit or delivery to himself from the seller or consignor.

(2) If such a sample has been so procured since the sample in question was procured, or had been so procured within 24 hours prior to that sample being procured, it is not necessary for the authority to procure another sample in accordance with the notice.

(3) The purveyor has no right to require that such a sample shall be procured if the milk from which the sample procured from him was taken was a mixture of milk produced on more than one dairy farm.
