Milk Supply of Ealing.
Total milk consumed per day = 7,985 gallons.
Total population, 1932 (April) = 117,900.
Average consumption of milk per person = 54 pint.
Total amount of milk Pasteurised =92 per cent.
Total amount of milk Pasteurised by Positive
holder method of a good type =76 per cent.
Total Certified (13| gallons) and Grade A
(T.T.) (27-|- gallons) =41 gallons.
= .5 per cent, of all
milk.
Total amount of milk sold loose =76 gallons.
approx. 1 per cent.
Total amount of milk included in total, but
apart from Graded milk, sold raw = 460 gallons.
= 5.8 per cent.
The figures quoted for Ealing indicate that but a very small
percentage of the highest grades, Certified and Grade A (T.T.),
of milk is sold, .5 per cent., and that only 1 per cent, of milk is
sold loose, that is, other than in sealed bottles or other sealed
receptacles (cartons). The amount of milk consumed per person
per day in Ealing is larger than the estimated average for the whole
of the country, over half a pint compared with a third of a pint.
This larger consumption may not be the result of greater appreciation
of the value of milk but an indication of better economic conditions
than exist generally, and especially in the large industrial towns.
Other interesting points are that not less than 92 per cent,
of the milk supply of Ealing is treated by heat—commonly called
pasteurisation—and that 76 per cent, is pasteurised as defined
in the Milk (Special Designations) Order. If so much as 92 per
cent, of milk is heat-treated and 76 per cent, is treated by the
approved method it ought surely to be quite a practicable matter
from a legislative standpoint to insist on the difference between
76 and 92 per cent, being treated by the approved method. Furthermore,
as we know that pasteurisation by the approved method
renders milk safe, that is, it kills any infective material which
may have gained access, and as we know that this treatment
does not to any appreciable extent interfere with the nutritive
