Twelve of the samples purchased in the Borough in 1920 were
not satisfactory; and, therefore, the percentage of non-genuine
samples amounted to 7 percent., as compared with 8 percent,
for the preceding year. This is below the figure for London
as a whole.
9.8 percent, of the 92 Milk samples were unsatisfactory, as
against 17 percent, during the preceding year; but in some cases
the deficiency below the legal limits was very slight.
In London as a whole, the percentage of Milk samples
reported against was practically the same as in Stoke Newington.
It should be added that many of the other samples purchased
were below the average quality of the milk supply of London,
although they were a trifle above the low legal limits which have
been fixed.
All the samples of Milk, Butter and Margarine were tested
for antiseptics, with the result that no sample of Milk, 6 of
Butter, and all the samples of Margarine were found to contain
boric acid. In no case was the amount sufficient to warrant a
prosecution; but in one or two instances the vendors were
cautioned.
Five informal samples have been taken during the year.
The informal samples collected did not lead to the detection of
adulteration.
Fifteen samples of milk were purchased on Sunday mornings.
