Of these 251 were submitted as formal samples while 749 were
purchased informally. None of the formal samples, and 2.0
per cent. of the informal samples, were found to be adulterated or
not up to standard. The total adulterations reported were 15 or
1.5 per cent. of the samples submitted.
The 15 samples found to be adulterated were:—
three samples of tomato ketchup, two of icecream and one
each of butter, cakeoma, fizz powder, peppermint flavour,
canned beans, fish powder, canned sliced apples, soused
herrings, bread, and lemonade powder.
It was not necessary to take Police Court proceedings in any of
the above cases of adulterated samples.
