One hundred and twenty-six samples of milk and six samples of separated milk were
taken at Paddington Station on delivery by rail. Fifteen of the milk samples were found to
be adulterated.
Sixteen samples of milk were obtained at Paddington Station at the request of other
Boroughs.
Sampling of milk supplies to Public Institutions.—There are seven institutions from which
samples of milk are taken quarterly and two from which samples are taken half-yearly.
Of the 32 samples taken in 1930 all were returned as genuine.
PUBLIC HEALTH (PRESERVATIVES, &c., IN FOOD) REGULATIONS, 1925 TO 1927.
With few exceptions all samples taken under the Food and Drugs (Adulteration) Act
were examined for the presence of preservatives. Two samples of sausages, sold without
proper declaration of the presence of preservative were found to contain respectively 82
parts and 99 parts per million of sulphur dioxide, and one sample of strawberry jam was found
to contain 67'95 parts per million of sulphur dioxide. The vendors were cautioned.
PUBLIC HEALTH (CONDENSED MILK) REGULATIONS, 1923 AND 1927.
During the year one sample of full cream unsweetened, four samples of full cream
sweetened, and eight samples of skimmed sweetened condensed milk were taken. All were
found to comply with the Regulations.
PUBLIC HEALTH (DRIED MILK) REGULATIONS, 1923 AND 1027.
No samples of dried milk were taken during 1930.
CHEMICAL AND BACTERIOLOGICAL EXAMINATION OF FOOD.
Analyses for the purposes of the Food and Drugs (Adulteration) Act, 1928, and the
various Food Regulations are made by the Public Analyst, Sir William R. Smith, at the
Royal Institute of Public Health, 37, Russell Square, W.C.1, where also bacteriological
examinations of food are made when required.
Bacteriological examinations of samples of milk procured under the provisions of the
Milk (Special Designations) Order, 1923, are also made at the Royal Institute of Public
Health.
During 1930 one sample of sausages was submitted for bacteriological examination
following complaint of suspected poisoning. No injurious organisms were found.
The results of other samples analysed or bacteriologically examined are recorded elsewhere
in this Report under the appropriate headings.
Summaries of the results of analyses made by the Public Analyst during the year are
given on pages 48 and 49.
The results of legal proceedings are summarised on page 52.
In connection with the analysis of milk samples, the Public Analyst furnishes the result
of his analysis and the following table is of interest. It may be noted that the Ministry of
Agriculture standards for presuming milk to be adulterated are 3 per cent. for fat and 8.5 per
cent. for non-fatty solids. These standards are generally considered to be rather unfair to
the consumer and the deduction to be made from the tables is that the milk sold in Paddington
is, generally speaking, of average natural strength.
