19.—(1) A sample of seed potatoes taken for any purpose in connection with these Regulations must be taken in accordance with this regulation.
(2) A sample must be taken by an authorised officer and may be of such quantity or number and from such part or parts of the growing or harvested crop as the authorised officer considers appropriate.
(3) Paragraph (4) applies where a sample is required other than for a purpose in connection with certification of seed potatoes produced in England, and the bulk consists of seed potatoes—
(a)comprising more than one consignment; or
(b)associated with more than one growing crop certificate.
(4) The seed potatoes must be divided so that each consignment or, as the case may be, the quantity of potatoes associated with each growing crop certificate, constitutes a separate lot and each lot must, if the authorised officer considers it necessary, be separately sampled.
