The year saw the end of the designation Tuberculin Tested both in
relation to raw and processed milk and in place the introduction of the
designation "Untreated". The passing of the designation "Tuberculin
Tested" is an indication of the progress that has been made with the
elimination of tuberculosis from the dairy herds of this country. It has, in
fact, been eliminated and appears to be fast becoming a rarity in the
animal world.
In October a new designation "Ultra Heat Treated" came into being.
This is a process whereby the milk is heated to and maintained at a temperature
of not less than 270° F. for a period of not less than one second and
then packed into sterile containers in which it is sold or delivered to the
consumer. Cartons are used in place of the conventional glass bottle and
the keeping quality of the milk is enhanced to such a degree that fresh
milk from this country is now obtainable in all parts of the world. A side
issue on the value of this milk may well be that British tourists travelling
on the continent can take a supply of fresh milk with them. With the
keeping quality of milk so improved, the day will assuredly come when it
is no longer necessary for the milk roundsman to make a daily call.
