The following list shows in detail the results of analysis of individual
samples other than milk, cream and spirits, which were adulterated and
the decision taken in each, with the result of any legal proceedings
ordered by the Council:—
Butter.—145 samples were taken and 1 contained 1.7 per cent. excess of water, the
vendor of which was cautioned by letter.
Sausages.—03 samples of various kinds were taken and 8 only contained the
preservative in the form of sulphur dioxide in parts varying from 90 to 500 per
million. The vendor of the sample containing the latter amount was cautioned by
letter. The amount of sulphur dioxide permitted is 450 parts per million.
Peas.—13 samples of tinned peas were taken and only 1 was found to contain
crystallised copper sulphate, which form of preservative is now forbidden. This
sample contained 0.2 grain per lb., and as it was taken unofficially no action was taken.
Tomatoes.—1 sample of tinned tomatoes was taken and found to contain 2.5 grains
of tin per lb. The vendor was cautioned by letter.
Mixed Vegetables.—3 samples were taken, 1 of which was found to contain -05 grain
of crystallised copper sulphate per lb. The quantity was so minute no action was taken
other than by the purchase of further samples which proved to be genuine.
Lemon Squash.—14 samples were taken, and 6 contained sulphur dioxide in parts
varying from 40 to 142 parts per million, the latter sample was found to contain in
addition to sulphur dioxide 100 parts of salicylic acid per million of lemon squash. The
vendor was prosecuted and ordered to pay £2 2s. costs.
Lime Juice.—6 samples were taken, 1 of which contained 150 parts per million of
sulphur dioxide. No action was taken as the amount was well within the prescribed
limit.
Fruit (tinned).—31 samples were taken and 2 were found to contain tin to the extent
of 3.86 grains per lb. each. The first was an unofficial sample, followed by the official
sample as soon as the Analyst's report was received, the vendor concerned was prosecuted
and fined £2 and £3 3a. costs.
Regulation of Street Trading.
The London County Council (General Powers) Act, 1927, provides
for the regulation of street trading by the issue of licences which must
he renewed annually. Special observation is kept by the Sanitary
Inspectors of all stalls where food is exposed for sale and the premises
where the food is stored. 'Where stall-holders have their food stores
in other districts the addresses are forwarded for the attention of the
sanitary authority concerned.
Meat Regulations, 1924.
There are no slaughterhouses in the City and the duties imposed are
confined to the supervision of meat shops, stalls and stores. In addition
to routine and special inspection, visits are paid to all meat premises in
Ithe City at certain periods in the year for the purpose of a general
inspection of the requirements in the Regulations. A register is kept of
all meat vendors and the number at the end of 1927 was 144, to which
the inspectors paid 428 visits.
