There were no prosecutions. Action taken on non-genuine
samples was as follows:-
969 (formal) Contained only 41 per cent of meat instead of
Sausage meat. not less than 50 per cent.
The matter was referred to the Ministry of
Food in order that they could take appropriate
action under the Meat Products and Canned Meat
(Control & Maximum Prices) Order,1948. It
was subsequently learned that a severe warning
had been given in this case.
990 (informal) This substitute contained not more than 5
Pepper. per cent of white and black pepper and not
less than 90 per cent of flour, with other
spices and flavouring.
Before a formal sample could be taken the
commodity had been designated "Pepper
compound" and, having regard to the amended
description, no further action was necessary.
1028 (informal) Contained 1.44% w/v of anhydrous quinine
Quinine,ammoniated instead of not less than 1.56% as specified
tincture of in the British Pharmaceutical Codex. The
matter was taken up with manufacturers and
stocks were immediately withdrawn from 3ale.
1048 (informal) Contained 70 parts of copper per million
Tomato Ketchup. parts of dried total solids whilst in the
opinion of the Public Analyst not more than
50 parts should be permitted. The matter
was taken up with the manufacturers and stock
were immediately withdrawn from sale.
ICE CREAM.
Premises have been registered by the Corporation under
Section 14, Pood & Drugs Act, 1938, as under:-
For manufacture, storage and sale 19
For manufacture, storage and sale
but manufacture to be limited to
i ce—1o11xes 13
For storage and sale, but not
manufacture 90
During the year 194 visits were made to premises and
vehicles and 141 samples of ice cream were taken for laboratory
examination for bacterial cleanliness, details being appended.
It should be borne in mind that the methylene blue test
for examining Ice-cream is still in the trial stage, and the
Public Health Laboratory Service advises that it is unwise to
Pay too much attention to the result of any one sample. Judgment
should be based rather on a series of samples. It Is suggested
that it would be reasonable to expect about 50 per cent of samples
throughout the year to fall into Grade I, 80 per cent into Grades
I or 2, not more than 20 per cent into Grade 3,and none into
Grade 4.
Owing to the large number of manufacturers whose ice-cream
was sold in the Borough during the year it was not possible to
take a series of samples from each, but as the table shows, efforts
were made to repeat unsatisfactory samples till improvement was
effected or the supply discontinued.
