at which milk is processed. This is equipped with pasturising
plant which is licensed by the Council under the provisions of the
Milk (Special Designation) (Pasteurised and Sterilised Milk)
Regulations, 1949-1953.
Most of the milk now consumed in the District is produced
and processed outside the District and retailed by the large dairy
companies.
Under the Milk (Special Designations) (Specified Areas)
Order, 1951, only milk bearing a special designation is permitted to
be sold in the District.
Milk Sampling.
A total of 247 samples was submitted to the methylene blue
(keeping) test and the phosphatase (pasteurisation) test, 198 being
'Pasteurised' milk, 23 'Tuberculin tested' (raw) and 26 'T.T.
(Pasteurised)'. Three of the 'Pasteurised' and 4 of the raw 'T.T.'
did not pass the keeping test. Of 27 samples of 'Sterilised' milk,
only 1 failed the turbidity test.
In addition 25 samples of T.T. and 12 of ungraded milk were
injected into guinea pigs for the biological test for tuberculosis
and all were negative, which is very satisfactory. As similar results
have been recorded throughout the County, decreased biological
sampling of T.T. milk is now thought justifiable.

ICE CREAM.
As this product has also caused cases of gastro intestinal
diseases in the past, its production and sale is kept under close
review. In 1956, 96 premises in the District were registered for
its sale, and a further 3 for its manufacture and sale. In a further
24 premises it is sold but these premises are exempt from registration.
One registration for sale was cancelled owing to a change
in character in the general business carried on at the premises
concerned.
One of the results of close supervision has been centralised
production, and with one exception, all the ice cream retailed in
