Forty-eight samples were found to be adulterated. In
addition 30 other samples were of inferior quality or
doubtful purity.
The adulteration was at the rate of 6.5 per cent. The
average adulteration for the London Boroughs in 1929, was
at the rate of 3.7 per cent., and for the whole of England
and Wales, 5.4 per cent.
The adulteration in the Borough for the previous seven
years was as follows:—
Year
No. of samples Percentage
Examined of adulteration
1929 750 8.0
1928 731 9.3
1927 728 9.2
1926 721 3.3
1925 745 3.9
1924 754 6.1
1923 736 5.6
Average 738 6.5
The adulteration after a temporary rise in amount now
appears to be falling, although still above the average.
The number of samples examined was at the rate of 6.7
per thousand of the population, as compared with an average
of 9.0 per thousand for the London Boroughs and 3.5 for
the whole of England and Wales.
MILK.
Two hundred and ninety-six samples of milk were
examined of which 20 samples, or 6.8 per cent, were found
to be adulterated. Although higher than the previous year
it is interesting to note that milk adulteration in London
has been steadily declining for some years.
The figures for the previous 5 years are as follows:—
Year
No. of milks
Examined
Percentage
adulterated
1929 287 5.2
1928 306 8.2
1927 275 5.4
1926 340 2.9
