During the year 89 samples of ice cream were taken for
bacteriological examination. The results of the methylene blue
test were as follows:—
64 samples were within Grade 1 standard
16 „ „ „ „ 2 „
5 „ „ „ „ 3 ,,
4 „ „ „ „ 4 „
Samples graded in 1 and 2 are considered satisfactory but
samples graded in 3 and 4 are doubtful. These results again
show an improvement on the previous year.
It should be pointed out that the four samples in grade 4
were manufactured outside this Borough.
In addition 35 samples of ice cream were taken for chemical
analysis, all of which complied with the standard laid down by
the Food Standards (Ice Cream) Orders, 1951/52.
Milk Supplies.
98 persons were registered as Distributors of Milk at the
close of the year.
Under the Milk (Special Designations) (Pasteurised and
Sterilised Milk) Regulations, 1949, the Minister of Food appointed
the 1st October, 1954, to be the date after which all pasteurised
milk should be placed in the containers in which it is sold on
the premises where it is pasteurised. The effect of this is that
only at licensed pasteurisers' premises can pasteurised milk be
bottled. Since sterilised milk must be bottled during processing,
and raw tuberculin tested milk is bottled on the farm, the small
retail milk bottler has now disappeared from London.

Designated Milk. During the year 126 samples of Special Designated milk were taken from milk distributors, milk processing depots, hos-pitals and schools and submitted for the phosphatase, methylene blue and turbidity tests, the results of which are set out below:—

The sample of tuberculin tested milk which failed to pass
the methylene blue test was reported to the Ministry of Agriculture
and Fisheries, this having been bottled on the farm.
Further samples from the same source proved to be
satisfactory.
