(c) Bacteriological Examination of Milk.

The samples of Pasteurised Milk were submitted for the Phosphatase
and Methylene Blue Tests, which are respectively tests of adequate
pasteurisation and satisfactory bacteriological condition. All
samples passed the test for which they were submitted. The sample
of sterilised milk passed the turbidity test which is the appropriate
one for this type of milk.
(d) Ice Cream.
The number of registered premises in the Borough in which ice
cream may be stored or from which it may be sold is 172. This
figure also includes five producers. In addition to these dealers
and producers, there are other premises, such as restaurants,
canteens, cinemas, etc. upon which ice cream is sold. These premises
are not required to be registered. By far the greater part of the
ice cream sold in the town is obtained from manufacturers whose
premises are situate outside the Borough. More than ever the production
of ice cream is being confined to the few large manufacturers.
The following table shows the results of examinations in
respect of 77 samples submitted to the Ministry of Health Public
Health Laboratory at Epsom during 1961. Owing to the numerous
factors governing the hygienic quality of ice cream, undue attention
is not paid to the bacteriological results on any single sample.
Those which are placed within Grades I and II are considered to be
satisfactory and those within Grades III and IV not so.
