The Ice Cream (Heat Treatment, etc.) Regulations, 1959, require
that ingredients used in the manufacture of ice cream be pasteurised
or sterilised.
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.

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 twentyfour
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 in connection with this scheme were
obtained during the year and 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.
There are no premises within the borough where poultry is
processed.
