The following 9 samples (2.9%) were reported as adulterated or
otherwise irregular:—
Beef Sausage.
Deficiency of meat of 5%. Warning given.
Dairy Butter Sweets.
These were found to contain 110 parts per million of sulphur
dioxide. Manufacturers maintained that sulphur dioxide was necessarily
introduced in process of manufacture. No action.
Butter (Informal Sample).
This sample was certified to be margarine. A subsequent formal
sample proved to be genuine.
Malt Vinegar.
On analysis this contained 0.8% added salt (sodium chloride).
Although not a normal constituent it was not injurious and in the
absence of a statutory standard for vinegar no action was taken.
Sausage Meat.
This was certified to be 24% deficient in meat. The case was
referred to the Ministry of Food who prosecuted. The vendor was
convicted and fined £10 and 5 guineas costs.
Milk.
This sample had a 1% deficiency of solids not fat. No action taken.
Tomato Sauce.
Found to contain sulphur dioxide to the extent of 125 parts per
million. The manufacturers explained that, in the manufacture of this
sauce, sieved apple pulp had been used and that the sulphur dioxide
found on analysis was derived solely from that source and that none
had been introduced otherwise. Sulphur dioxide in fruit pulp is
statutorily permissible.
Brown Sugar (Informal Sample).
This was certified to contain soda. The matter was taken up with
the vendor, but, in view of the circumstances of the case, legal action
was unlikely to be successful.
Whisky.
This was found to be 37.5 degrees under proof against the statutory
limit of 35 degrees u.p. The vendor's explanation that the dilution
was due to the sample being measured into a wet container was accepted
with a warning.
