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 21 samples of ice cream were also taken and submitted to the methylene blue test. The results are as follows:-
Grade | No. of samples |
---|---|
1 | 6 |
2 | 2 |
3 | 2 |
4 | 11 |
Premises in the borough 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, 1959.
General
There are no abattoirs or slaughterhouses in the borough, and no
killing of animals for human consumption is carried out.
