The percentages of samples of Pasteurised and Heat Treated Milk
wnich were satisfactory, as judged by the Methylene Blue (keeping) test
and Phosphatase (pasteurisation) test, compared very favourably with
those for 1948 in spite of the very hot weather experienced during the
summer months.
It is very gratifying to record that virtually all the milk sold by retail
in the District is pasteurised or otherwise designated.
As a result of representations made to the Divisional Veterinary
Officer of the Ministry of Agriculture and Fisheries, in respect of the two
T.B. positive biological milk samples, two cows were removed from the
herd in question.
Subsequent samples taken by the Divisional Veterinary Department
proved negative.
Milk (Special Designations) Regulations, 1936/49.
Licences to sell milk under the above Regulations were issued as
follows:—
Dealers:
Tuberculin Tested 7
Pasteurised 9
Sterilized 11
Supplementary:
Tuberculin Tested 8
Pasteurised 7
Sterilized 6
ICE-CREAM.
Under the provisions of Section 64 of the Coulsdon & Purley Act,
60 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 17 premises exempt from registration.
The bulk of the ice-cream retailed in the District is obtained by the
vendors from manufacturers situate outside the Council area.
A total of 90 samples of ice-cream, including 7 ice lollies, were
examined for bacterial quality by submission to the methylene blue reduction
test.
The samples were placed in the following provisional grades :—
Ice-cream. Ice Lollies.
Grade I 36 7
Grade 11 21 —
Grade III 21 —
Grade IV 5 —
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 a table such as the above, the proportion of unsatisfactory samples
will, of course, be influenced by the percentage taken from suspected
sources, and it should be noted that 3 of the Grade IV samples were in
fact obtained from the same source. Furthermore, all the samples of
this grade were obtained from retailers purchasing their supplies from
outside the District.
