The grading is based on the results of the Methylene Blue Reductase Test and a summary of this year's reports is given below:—
Samples taken | Time taken to Reduce Methylene Blue | Provisional Grade | Observations |
---|---|---|---|
34 | 4½ hours or more | 1 | Satisfactory |
22 | 2½ to 4 hours | 2 | Sub-standard |
3 | ½ to 2 hours | 3 | Unsatisfactory |
2 | 0 hours | 4 | Most Unsatisfactory |
6 | Ice-lollies | Plate count and bacteria reports showed these samples to be Satisfactory |
On receipt of a Grade 3 or 4 report it is the practice in this
Borough to obtain further samples from a vendor before administrative
action is taken. It was not necessary during the year to have
recourse to ' administrative action.'
Quantitative Analysis.—Standards for the composition of ice
cream were first laid down in the Food Standards (Ice Cream)
Order, 1951. However, on 7th July, 1952, the legal minimum
quantity of fat and milk solids other than fat required to be contained
in ice cream were reduced by the introduction of the Amendment
Order of 1952. The original standards were re-introduced with
effect from 1st June, by the Food Standards (Ice Cream) Order, 1953.
In connection with quantitative analysis, 9 samples of ice-cream
and 2 ice-lollies were examined in the normal course of food sampling.
All samples proved to be satisfactory and reference to the Analyses
will be found under the heading of Food and Drugs Act, 1955.

food voluntarily surrendered during the year under the provisions
of the Public Health (London) Act, 193(1, Section 180(8) most of
