Mr. Amphlett Williams makes the following observations on this analyses during
the year:—
"Adulterated Samples.—The percentages of samples which were reported as
adulterated, not up to standard or improperly labelled, during the last five years
are given below:—
1934 1935 1936 1937 1938
Percentage adulterated 3.8 6.6 5.2 9.1 4.2
The very high percentage in 1937 was largely influenced by the number of
samples of canned sild which were contaminated with tin, 31 samples having been
condemned, of which 24 were of one particular brand. In 1938, only 7 samples
were condemned on this account and the percentage of other adulterated samples
accords closely with the general average of other Metropolitan Boroughs.
Composition of Milks.—The average percentages of fat and of solids-not-fat
found in the samples of milk analysed during the past five years are given below;
the averages have been calculated for each quarter as well as for the whole year,
and thus show the regular seasonable variations in the quality of the milk. All
the samples analysed have been included excepting those definitely adulterated,
of which particulars will be found elsewhere.
