BACTERIOLOGICAL PURITY OF MILK.
The Council may be interested in the following
summary of a paper I submitted at a joint meeting of
the Society of Medical Officers of Health (Metropolitan
Branch) and the Society of Chemical Industry (Food
Section), on " The Bacteriological Standards of Milk."
The present evidence concerning the production of milk
leads to the conclusion that a certain bacteriological content
is inevitable and normal. This has led to the Milk (Special
Designations) Orders, 1922 and 1923, laying down definite
standards for certain specified grades, with the object of
bringing the bacteriological content under control. It is
clear, however, from statistics published by London Medical
Officers of Health that these standards are not very satisfactorily
observed. In 1931, over 10 per cent, of the
samples taken were unsatisfactory, the worst grade in this
respect being Pasteurised Milk. The amount of sampling
done and the results obtained vary to an extraordinary
extent from borough to borough. Among those boroughs
which carry out a fair amount of sampling, the percentage
of samples contravening the standards range from 3.3 to
44.4. The most frequently tested grades are Grade A
(Tuberculin Tested) and Pasteurised, and the percentage of
unsatisfactory samples varies from 3.3 to 36.5 in the case
of the former and from 9.0 to 46.6 in the case of the
latter grade,. (In Bethnal Green, the average percentage
