The dairy company maintains a twenty-four hour laboratory
service to control the purity of the milk passing through
the depot, and approximately a quarter of a million chemical
and bacteriological tests are made during the course of a year.
The depot now serves 96 distributing dairies within a
radius of 15 miles.
Originally all milk was delivered to the depot by rail and
road in 17 gallon churns. This method of delivery resulted
in an undesirable rise in the temperature and to-day 95 per
cent. of the milk arrives in glass lined road or rail tanks at
a temperature of 40°F. The milk is cooled and cleaned at the
company's own cooling stations before being put into the
tanks.
During the past year the use of wide neck bottles and
card disc stoppers has been dispensed with in favour of the
more hygienic narrow neck bottle with aluminium cap. This
entailed the abolition of the existing filling and capping
machines and the installation of 9 of the latest vacuum operated
filling and capping machines which together are capable
of filling and capping 1.000 bottles a minute.
Frequent inspections by the visiting Inspector are maintained
including the examination of thermograph charts;
which are preserved to allow of examination by the Inspector
at his next visit; the checking of thermometers; the taking of
samples, and the conduct of the establishment in every hygienic
respect.
DESIGNATED MILKS — MILK (SPECIAL DESIGNATIONS)
ORDERS, 1936 AND 1938.
82 samples of graded milks were examined, as follows:—
Pasteurised 70
Accredited 7
Tuberculin Tested 5
All samples satisfied the prescribed tests. In addition,
20 samples of pasteurised milk were submitted for the phosphatase
test—a test devised to indicate that milk has been
adequately heated. 10 samples were examined for tubercle
bacilli; all were satisfactory.
