In no case was Faecal Coli found.
The Public Health Laboratory Service advises that it is
unwise to pay too much attention to the result of any one
sample. Judgment should be based rather on a series of samples.
It is suggested that it would be reasonable to expect about
50 per cent of samples throughout the year to fall into Grade I,
80 per cent into Grades 1 or 2, not more than 20 per cent into
Grade 3, and none into Grade 4.
The eighteen Grade IV reports which spoil our record were
from two sources of supply which, being unsatisfactory, were
repeatedly sampled with varying results. One of these supplies
was eventually discontinued.
Very little ice cream is now made in this district and of
the 174 samples only 14 (6 being lollies) were of local
manufacture.
Each retailer from whom a sample was taken was supplied with
a copy of the laboratory report, and a Sanitary Inspector visited
the premises and gave advice where reports were not up to the
standard expected.
Where manufacture took place outside the Borough copies of
reports whether good or otherwise were also sent to the
Sanitary inspector for the district concerned for his information
The Food Standards (Ice Cream) (Amendment) Order, 1952,
came into operation on 7th July, 1952, and reduced the minimum
fat content of ordinary ice cream from 5% to 4% and the minimum
non-fat milk solids from 7½%to 5%. ' Sugar remained unchanged
at 10%. There were similar alterations for ice-cream
containing fruit and for Kosher ice.
Seven samples were taken to see that the proper standard
was reached and six wore found in order. The seventh was
deficient in non-fatty solids and a warning letter was sent to
the manufacturers.
