The Public Health Laboratory Service advises
that owing to the numerous factors governing the hygienic
quality of ice-cream it is unwise to pay too much attention
to the bacteriological results on any single sample.
Judgment should be based rather on a series of samples. It
is suggested that over a six monthly period, 50% of a
vendor's samples should fall into Grade 1, 80% into Grades
1 or 2, not more than 20% into Grade 3, and none into Grade 4.
The results above show that a very high standard
of hygienic quality is being maintained both by manufacturers
and retailers.
There are now no manufacturers of ice cream
within the Borough.
During the year three new regulations with
regard to the labelling and composition of ice cream came
into force.
The effect of these is (briefly) (a) to prohibit
the labelling, marking or advertising of ice-cream in a
manner suggestive of butter, cream, milk or anything
connected with the dairy interest unless it contains no
other fat than milk fat (with certain exceptions), (b) to
prescribe amended standards of composition for ice-cream
of various descriptions, and (c) to amend the conditions
relating to the heat treatment of ingredients.
