These factors, although of a temporary nature, had an
adverse effect upon the keeping qualities of the milk. It Is
gratifying to report that the "follow up" samples of these milks
were satis factory.
The failure of one Pasteurised milk sample to pass the
Phosphatase test occurred during the dismantling of the dairy
plant, and the Installation of new machinery. During this period
the milk was processed by another Company. It will be seen that
a total of four samples only failed to pass the various tests In
1951, as compared with eleven In 1950.
Biological Milk Samples, Eleven samples of Tuberculin
Tested milk were taken and results showed that guinea pigs
Inoculated with the milks failed to show any signs of a tuberculous
Infection on post-mortem examination.
ICE CREAM
Registrations,. At the end of 1951, a total of 189 premises
had been registered for the sale of Ice cream in accordance with
Section 14 of the Food and Drugs Act 1938, and on six of these
premises ice cream could be manufactured.
It Is of Interest to note that the amount of Ice cream
manufactured in the Borough has gradually diminished during the
last year or so.
At one factory the manufacture of Ice cream has practically
ceased, whilst at another three premises the quantity now made
is negligible.
It would appear that the main cause for this change is an
increasing public demand for the more popular and well-known
brands of Ice cream.
During the year sixteen new applications for registration
of premises were received and granted as shown in the following
table:-
