standard required in the Milk (Special Designations) Order for Certified Milks
which is the highest grade of designated milks is as follows : —
On a sample being taken at any time before delivery to the consumer the
milk shall be found to contain—
(a) not more than 30,000 bacteria per cubic centimetre, and
(b) no coliform bacillus in one-tenth of a cubic centimetre.
