It is gratifying to record that the proportion of samples with the
specified requirements of Grade I and II has steadily risen during the
past 5 years. The percentage of samples in these grades being as
follows:—
1947—35%, 1948—53%, 1949—74%, 1950—85%, 1951—94%.
For the first time a minimum standard quality was legally prescribed
by the Food Standards (Ice Cream) Order, 1951, which came into force
on the 1st March, 1951. This requires that ice cream shall contain
5% fat—not necessarily cream—10% sugar and 7½% milk solids other
than fat. Eighteen samples were submitted to the public analyst during
the year and all but one were reported as genuine.
Meat and Other Foods.
All meat sold by retail is supplied from Ministry of Food depots
outside the district. No slaughtering within the district is carried on
as far as is known. Inspection of meat, therefore, is limited to that
displayed for sale or held by retailers prior to sale.
Approximately 2,000 lbs. of meat were found to be unfit for human
food.
