5.—(1) The Department shall—

(2) In relation to any sample, if the interval between sampling and laboratory analysis is likely to exceed four hours, the Department shall conserve the sample in a refrigerator.

(3) The Department shall ensure that the time between sampling and laboratory analysis does not exceed 24 hours and must use its best endeavours to keep this time as short as possible.

Reference methods of analysis

6.—(1) Subject to sub-paragraph (2), the Department shall use the following reference methods of analysis—

(a)for Intestinal enterococci, ISO 7899-1 or ISO 7899-2; and
