The principal conditions applying to the various classes of milk
under the Milk (Special Designations) Order, 1923, are as follows :—
"Certified" Milk is required to be produced from cows which
have passed the tuberculin test and veterinary examination. This
test and examination must be made at intervals of 6 months, and
every animal added to the herd must be tested immediately before
admission. The milk must be bottled on the farm and must
not contain more than 30,000 organisms per c.c., or any coliform
organism in 0.1 c.c.
"Grade A (Tuberculin tested)" Milk is subject to the same
conditions as Certified Milk as regards the testing and examination
of cattle. The milk must be bottled before distribution and must
not contain more than 200,000 organisms per c.c., or any coliform
organisms in 0.01 c.c.
"Grade A" Milk must satisfy the same conditions as "Grade
A (Tuberculin tested)" milk, with the exception that the tuberculin
test is not required, and that veterinary examinations of the
cows in the herd are made at intervals of 3 months instead of 6
months.
"Pasteurised" Milk is milk which has been pasteurised by
the holder process as defined in the Order, i.e., it must be held at
a temperature of 145 deg. to 150 deg. F. for at least half-an-hour,
and then cooled to 55 deg. F. It must not be heated more than
once and it must not contain more than 100,000 organisms per c.c.
If the milk so treated is Grade A milk, the number of organisms
must not exceed 30,000 per c.c., and there must be no coliform
