been responsible for the infection. Her milk was in the original
unsatisfactory bulk sample, but she had subsequently been sent
to the knacker. Group samples taken from the remainder of
the herd proved negative.
Milk (Special Designation) Regulations, 1949.
Licences to sell milk under the above Regulations were
issued as follows:—
Dealers:
Tuberculin Tested 11
Pasteurised 12
Sterilised 13
Supplementary
Tuberculin Tested 10

ICE-CREAM.
Under the provisions of Section 64 of the Coulsdon & Purley
Act, 70 premises within the District are registered for the sale
of ice-cream and 4 in respect of the manufacture and sale of
this commodity. In addition, the sale of ice-cream is carried
on from 22 premises exempt from registration.
The bulk of the ice-cream retailed in the District is obtained
by the vendors from manufacturers whose premises are situated
outside the District.
A total of 95 samples of ice-cream were examined for
bacterial quality by submission to the methylene blue reduction
test. The samples were placed in the following provisional
grades : —
Grade I 50
Grade II 28
Grade III 11
Grade IV 6
Grade I and II samples can be considered satisfactory ;
only about a fifth of the samples taken from any dealer should
be of Grade III quality, and none of Grade IV.
In statistics such as the above which compare very
favourably with those of the previous year, the proportion of
unsatisfactory samples is, of course, influenced by the percentage
taken from suspected sources, and it should be noted that
of the 17 samples in the two lower grades, 5 were obtained from
the same source.
Appropriate investigations and representations are made
following the receipt of all adverse reports, with a view to
encouraging an improvement in future supplies.
