Ice Cream.
102 Samples of ice cream were obtained during the year and
were submitted for bacteriological examination at the Public
Health Laboratory, Churchfield Road, Ealing.

The results, in accordance with the provisional grading scheme recommended by the sub-committee of the Public Health Laboratory Service appointed for the purpose, were as follows:

Provisional GradeNo. of SamplesPresumptive Coliforms PresentFaecal Coliforms Present
14911
24420Nil
344Nil
454Nil

The reports of the sub¬committee point out that owing to
the numerous factors governing the hygienic quality of ice cream
and to the experimental error of the laboratory test itself, it is
unwise to pay too much attention to the bacteriological results of
any given sample. Judgment should be based rather on a series
of samples. The majority of samples from any one producer
should fall into Grades 1 and 2 (50% in Grade 1 and 80% in
Grades 1 and 2). In those cases where unsatisfactory samples
were taken from local producers or retailers, further visits were
paid to the premises and advice was given by the Sanitary Inspectors
on questions of hygiene. Further samples were afterwards
taken and it was found that improvement had taken place, resulting
in the samples reaching the required standard. Where the source
of manufacture lay outside the Borough, the Public Health
Departments of the districts concerned were notified and similar
steps were taken by them.
Synthetic Cream.
13 Samples of synthetic cream were taken during the year
from local manufacturers and all received satisfactory bacteriological
reports.
Meat and Other Foods.
The following foodstuffs were condemned by the Sanitary
Inspectors as unfit for human food in the course of their inspections
of the various food premises in the Borough:—
