(c) Bacteriological Examination of Milk.

All the samples of Pasteurised Milk passed the phosphatase test
which indicates that the milk has been properly pasteurised. The
methylene blue test is a measure of the bacteriological condition of
the milk and in accordance with the standard set by the Milk (Special
Designations) Regulations 1960, this test is void if the atmospheric
shade temperature exceeds 700 F. during the period of the test.
The two samples of Tuberculin Tested Milk which failed the test
were from the same source. Appropriate follow-up action is being taken.
(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 173. This figure also
includes five producers,, In addition to these dealers and producers,
there are other premises, such as restaurants, canteens, cinemas, ete.
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 79 samples submitted to the Ministry of Health Public Health
Laboratory at Epsom during 1962. 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. Adequate follow-up action is taken where samples
fall within the latter grades.
