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 decolourise 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, thirty-three samples of ice-cream were taken and
submitted to the methylene blue teste The results were as follows:-
Grade
Number of samples
1
7
2

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,
The Liquid Egg (Pasteurisation) Regulations, 1963.
These Regulations require the pasteurisation of liquid egg to be used
in food intended for sale for human consumption, other than egg broken out
on the food manufacturers' premises and used within twenty-four hours.
The Regulations prescribe the method of pasteurisation and the test to be
satisfied.
There are no egg pasteurisation plants in the borough and it was not
found necessary during the year to take any samples of liquid egg in
accordance with these Regulations.
Pesticides Residues in Foodstuffs.
In January, 1966, the Council agreed to participate in a scheme,
proposed by the Association of Public Analysts, to enquire into the
contamination of food by toxic chemicals. The enquiry was arranged to
cover a two-year period commencing 1st August, 1966, and each local
authority participating in the scheme was required to obtain and submit
for analysis eighteen samples each year.
The first eighteen samples were obtained during 1967 and the
remaining eighteen samples were obtained during 1968„ The results of
the analyses were all satisfactory.
Generally.
There are no abattoirs or slaughterhouses in the borough, and no
killing of animals for human consumption is carried out.
