The foregoing table shows in detail the results of analysis of individual
samples other than milk and spirits, which were adulterated, and the
decision taken in each case, with the result of any legal proceedings
ordered by the Council.
Jams and Preserves.—Thirty-seven samples of various kinds were
purchased and one (informal), namely, green fig and ginger marmalade,
contained 75 parts of sulphur dioxide (35 parts in excess of what is allowed).
An official sample taken subsequently was analysed and found to be
genuine.
Sausages.—Seventy-eight samples were taken, and in three instances
the presence of preservatives was not declared by means of labels as
required by the Regulations. The quantity of sulphur dioxide present
was found to be well within the prescribed limit. Two of the vendors were
fined £1 each, one having to pay £2 costs. In the remaining case the
magistrate came to the conclusion that there was some doubt in the
matter, and dismissed the summons.
Drugs.—Twenty-three samples were taken. One sample of light oxide
of magnesia was found to lose on ignition 6-94 per cent, instead of not
more than 1 per cent.; it also contained an appreciable quantity of carbon
dioxide. One sample of light magnesia consisted entirely of light carbonate
of magnesia. Both these adulterated samples were unofficial.
Subsequent official samples obtained were on analysis found to be genuine.

Caviare.—The question of preservatives in caviare was discussed
during the year. The federation of caviare importers reported that they
were still experimenting with methods such as cold storage to obviate
the illegal practice of adding boric acid as a preservative. A prosecution
had taken place in 1930 in respect to caviare containing boric acid.
Samples of caviare taken in 1931 contained no preservative.
Regulation of Steeet Trading.
The London County Council (General Powers) Act, 1927, provides for
the regulation of street trading by the issue of licences which must be
renewed annually. Special observation is kept by the Food Inspectors
on all stalls where food is exposed for sale and also the premises where
it is stored. Where stall-holders have their food stores in other districts
the addresses are forwarded for the attention of the sanitary authorities
concerned.
