There is still no legal bacteriological standard for ice cream.
As in previous years, samples were taken and submitted for examination
under the provisional methylene blue reduction test which is a simple
and practical means for the routine examination of ice cream. The test
is not of sufficient precision to justify its use as a statutory test.
The grading is determined by the length of time taken to decolourize
the methylene blue and it is suggested that if samples consistently
fail to reach grades 1 and 2 it would be reasonable to regard this as an
indication of defects in manufacture or handling which warrant further
investigation.
During the year eleven samples of ice-cream were also taken
and submitted to the methylene blue test. The results are as follows
Grade

Premises in the borougfr where ice cream is manufactured, stored
or sold were frequently inspected during the year and generally were
found to be in a satisfactory condition, having regard to the Ice Cream
(Heat Treatment, etc.) Regulations, 1947/52.
General
There are no abattoirs or slaughterhouses in the borough
and no killing of animals for human consumption is carried out.
