lor registration and, subject to compliance with the conditions governing the
registration of retail milk sellers, are so registered.
It would be an advantage if all such places were required by law to be
registered not only ft.r the sale of milk, but for the preparation and sale of food
generally
Mill; (Special Designations) Order, 1922.
This Order issued by the Minister of Health on December 9th, 1922,
prescribes the terms and conditions subject to which licences may be granted for
the sale of milk designated as "Certified," "Grade A (Tuberculin Tested),"
"Grade A." or "Pasteurised." These milks are to be sold under licences which
will expire on the 31st December in each year. Producers, i.e., dealers
having control of a herd from which milk is obtained will be licensed by
the Ministry of Health, County Councils, or the Councils of County Boroughs.
Non-producers who sell "designated" milk will be licensed by sanitary
authorities; in London, Metropolitan Borough Councils.
The schedules of the Order set out the conditions under which licences may
be granted, suspended or revoked, and provide for the fees payable for licences.
Up to date of the preparation of this Report licences for the sale of
designated " milk in the Borough have been issued as follows:—
Certified Milk. 3
Grade A Milk 2
Supplementary (Certified) 1
Pasteurised Milk.
In the course of enquiries made of the managers of large milk depots
respecting the sale of certified, Grade A and pasteurised milk, they
expressed the view that sale of milk designated " pasteurised " is not
likely to become popular at present. Many wholesale milk sellers habitually
pasteurise the milk which they receive before releasing the same for retail sale
and although they will continue to do this it is unlikely they will apply for
certificates to "designate" and sell the same as " pasteurised " milk.
It is suggested that the public would not be disposed to pay a higher price
for pasteurised milk and the sale of such milk without the designation obviates
compliance with the regulations. In one case it was pointed out that on the
completion of pasteurising, the milk is put through a cooler. On bacteriological
examination after coding the first half churn is frequently found to contain
bacteria exceeding the numbers allowed by the Order. It is the practice to return
this half churn for repasteurising. If the milk were sold under the designation
of "pasteurised" milk this practice would be illegal and the milk wasted or sold
with unpasteurised milk notwithstanding its high percentage of bacteria.
The advantages of clean milk as opposed to pasteurised milk were set forth
in a paper read by the writer at the Annual Conference of the Royal Sanitary
Institute at Folkestone in 1921.
Dirty Milk.
During the year 1922 arrangements were initiated for the systematic
examination of samples of milk for the presence of dirt.
One hundred samples were tested. In 8 cases evidence of the presence of dirt
was discovered ranging from faint traces to 7 parts per 100,000 by volume.
