ICE CREAM.
The Ice Cream (Heat Treatment) Regulations came into
operation on 1st May, 1947.
There are one hundred and thirty-five premises registered
to sell Ice Cream and seven premises to manufacture Ice Cream
in this Borough.
There was a very slight deterioration in the bacteriological
results compared with 1949.
Seventy-seven samples were submitted for chemical
examination the lowest fat content was 2.65% and the highest
20.75%.
In addition, seventeen Chocolate Ice Cream samples were
submitted for chemical examination, the lowest fat content being
4.0%, and the highest 25.6%.
Week-end samples were obtained from itinerant dealers
selling in the district. The Department has no prior knowledge
of their visits or sites from which sales take place.
It is, however, significant that pathogenic organisms have
not been cultivated in any sample examined since the inception
of the tests in 1947.
