The amount of adulteration detected during the year was:
For formal samples 0.18 per cent.
For informal samples 0.82 per cent.
For all samples 0.64 per cent.
Case No. 22
Complaint Samples
Chocolate Fudge: This sample was suspected to
have caused sickness. It was found that it contained
no ingredient likely to cause harm, although it
was rather poorly mixed. The complaint was
considered not justified.
Case No. 52
Butter: This sample, which it was suggested contained
margarine, was found to be 100 per cent.
butter.
Case No. 53
Christmas Pudding: This sample showed no evidence
of deterioration and is quite suitable for sale.
There is no evidence of mould-growth, the fat has
no taste of acidity or rancidity and though there is
a large proportion of dried fruit there was no sand
nor grit present. The complaint that it contained
sand was considered not justified.
Case No. 55
Crumpets: Examination of these crumpets has
yielded nothing to which one can take exception.
The fat obtained from them had a low acid value
and showed no trace of rancidity. The complaint
was not justified.
Cases Nos.
111 and 112
Coffee and Chicory Extract: These samples showed
no signs of fermentation, as the complainant
alleged. There are no yeast cells present nor any
development of acidity. The screw caps on the
bottles both show traces of mould. It is possible
that contents of some bottles have become contaminated
from dirty caps.
