Milk (Special Designations).
Under the two sets of Milk (Special Designations) Regulations
issued in 1949, four designations are prescribed, namely, Accredited,
Tuberculin Tested, Pasteurised, and Sterilised. Accredited Milk
may not be heat-treated. Tuberculin Tested milk may be pasteurised
or sterilised, provided it is so described. Pasteurised milk must be
so treated by either the "Holder" or "High Temperature Short Time"
processes, and must comply with the " phosphatase " and " methylene
blue " tests. Sterilised milk must be filtered or clarified, homogenised,
and heated to and maintained at a temperature of not less than
212° F. for such time! as will ensure that it complies with the
" turbidity " test.
All persons who pasteurise or sterilise, or deal in special
designation milk, are required to hold licences, which (except in the
case of producers of raw milk) are issued by Food and Drugs
Authorities.

Two licences to pasteurise, and one to sterilise milk were issued,
and are included in the above figures.
Details of examination of samples of pasteurised and sterilised
milk are given on page 34.
Ice Cream Premises.
The number of premises registered for the manufacture, storage,
and/or sale of ice cream at the end of the year was 105, 25 having
been added and 6 removed during the course of the year.
All these premises are regularly inspected, 221 visits being made.
Particular attention is paid to premises where manufacture takes place,
and not only are the premises, plant, and methods of operation
scrutinised, but samples of the products are taken for examination by
the methods suggested by the Ministry of Health. The premises
generally are found to be well conducted. Further reference to
sampling of ice cream will be found on page 35.
Fish Shops.
Shops in which fish, either cooked or uncooked, is sold, or where
the curing or smoking of fish is carried on, are regularly inspected.
There were 58 such shops in the Borough in 1950. 252 inspections
were made, and 1 notice was served, for minor matters which were
remedied without difficulty.
