Designated Milks.—Under the Milk (Special Designations) Order, 1936, all
licences for designated milks can now be granted by Metropolitan Borough Councils.
This Order revokes that of 1923 and reduces the number of designated milks to
three, namely (a) "Tuberculin Tested"; (b) "Accredited"; and (c)"Pasteurised."
Milk may also be sold as "Tuberculin Tested (Pasteurised)" if two licences are
granted, and where "Tuberculin Tested" milk has been bottled at the place of
production the word "Certified" may be added. Each licence automatically
terminates on the last day of the year on which it is issued. In tabular form is
shown below the number of licences so issued during the period:—
Number of pasteurisers' licences issued 1
Number of dealers' licences issued to use the designation:—
(a) "Accredited"
(b) "Tuberculin Tested "17
(c) "Pasteurised" 33
Number of supplementary licences issued to sell:—
(а) "Accredited" Milk
(б) "Tuberculin Tested" Milk 4
(c) "Pasteurised" Milk 8
Bacteriological Examination of Milk.—The number of samples of milk examined
bacteriologically during the year was 72: two of raw milk, sixty-eight of pasteurised
milk, and two of tuberculin tested milk.
No samples of milk were examined for the presence of tubercle bacillus. The
test now prescribed for tuberculin tested milk is known as the Methylene Blue
Reduction Test and the two samples of tuberculin tested milk examined passed this
test. Two samples of bulked raw milk were examined before pasteurisation and
each had a plate count of over five million. After pasteurisation the counts, which
are included in the Table set out below, were 12,200 and 36,400 respectively. Table
No. 26 which follows, gives detailed results of the examination of samples of
pasteurised milk.
