Comparing with last year's results, it is found that this year, there is
a small increase of the percentage in Grade I hut with a lower percentage in
Grades I and II; this is due to an increase in those of Grade III. Overall
the results are not quite so good as last year's figures, hut with the
exception of one sample in Grade IV the results are well within the standard
mentioned earlier in this part of the report.
There are also forty-three premises registered for the storage and sale
of ice cream, adding two new registrations during the year.
DAIRIES, COWSHEDS AND MILKSHOPS.
The control of the production of milk is vested in the Ministry of
Agriculture Fisheries and Food.
The local authority is responsible for the inspection and registration
of milk distributors and other dairy premises not directly concerned with the
(17)
connection with shop premises are referred to this Department for consideration
under the provisions of the Shops Act.
ICE CREAM.
All samples of ice-cream are taken to the Central Public Health Laboratory
Colindale, for testing by the Methylene Blue Test. This is merely
indicative and provides no legal standard: the Public Health Laboratory
Service suggest that owing to the numerous factors governing the hygienic
quality of ice-cream it is unwise to pay too much attention to the bacteriological
results on any single sample, judgement being based rather on a
series of samples. It is suggested as desirable that at least 50% should
fall into Grade I, 80% into Grades I or II, not more than 20% into Grade
III and none into Grade IV.
Seven samples taken from retailers in the district were all returned as
Grade I.
