Adulterated Samples.
The Public Analyst reported adversely on four formal samples—
butter, sultanas, pork sausages and frankfurters. The butter contained
an excess of 0.22 water, the sultanas contained a live maggot, and the
frankfurters a fly. A reprimand was sent to the manufacturers of the
butter and the frankfurters, and the shopkeeper was advised regarding
the sultanas. The pork sausages were reported as having only a
meat content of 57%, which is below the generally recognised standard,
but they were otherwise genuine and no action could be taken.
Heat Treated Milk.
Samples of pasteurised and sterilised milk are taken at regular
intervals for submission to the Public Health Laboratory Service for
the prescribed tests, and during the year samples as under were taken
with the result set out:-
Phosphatase

Methylene Blue

Pasteurised 28 — 28 —
Turbidity

Sterilised 24 —
Monthly returns of the samples taken, and of the results of the
examinations, are sent to the Milk Division of the Ministry of
Agriculture, Fisheries and Food, and they are at once notified of
any adverse report.
Milk supplied in Schools and Hospitals.
Samples of milk in course of delivery to Schools and Hospitals
in the Borough are taken, both for chemical analysis and for submission
to the prescribed tests for such milk. The samples are included
in the general totals given on pages 31, 33 and 35. The results of the
analysis and tests are communicated to the London County Council
or the appropriate Hospital Management Committee.
Ice-Cream.
Twenty-six samples of ice-cream were taken during the year, each
samples being submitted to the methylene blue test.

Where samples of ice-cream made at premises in the Borough
receive unsatisfactory reports, the premises, plant, and methods of
operation are examined, and, where possible, improvements are
suggested.
