REGISTERED PREMISES
Ice Cream
During the year 46 samples were taken for bacteriological examination.
The results of these examinations are as follows
Grade I 19
Grade II 3
Grade III 10
Grade IV 3
Not Graded 7
3 Lollycreams were examined, 2 were satisfactory and 1 doubtful.
In addition to the above, 1 Strawberry Puree was examined and found
satisfactory.
No cases occurred during the year of ice cream being in such poor bacteriological
condition as to necessitate the stoppage of sale, but the results
obtained from this year's sampling suggest that vigilance is still required to
maintain the purity of the ice cream supplied for public consumption. The
sampling results in 1955 are not so satisfactory as in 1954, and it was found
necessary to pay several visits to one premises to suggest possible improvements
in the methods of handling and distribution in order to obtain purer samples.
The reason that a certain number of the specimens are reported as nongraded
is usually because grading of coloured ice cream and chocolate ice cream
by the methylene blue test is not a very reliable one. The result of the
bacteriological plate count combined with knowledge of the nature of the organisms
found in these particular types of ice cream preparations is the basis from
which deductions can be drawn, The total number of samples tested by the
laboratory during the year was rather low, This was because we had been asked
to reduce the number to a minimum whilst alteration work was being carried out
at the laboratory premises in Ealing, and although the laboratory staff were
prepared always to deal with special samples in the case of emergency requirements,
we were expected to reduce the number of routine samples,,
Pour new premises were registered during the year in accordance with
Section 14, Pood & Drugs Act, 1938, for the sale of ice cream
The total number of ice cream premises on the register at the end of the
year was as under:-
Sale only 174
Manufacture and Sale 4
Storage only 1
179
