In the course of the year 191 samples of Pasteurised or
Tuberculin Tested Pasteurised milk were submitted to the Park
Hospital Laboratory, Hither Green, to assess the keeping quality
of the milk by means of the Methylene Blue Test. Twenty of the
samples submitted, however, could not be tested as the shade
temperature exceeded 65ºF, but the remaining 171 samples all
passed the test satisfactorily.
To determine the adequacy of pasteurisation, 197 samples
of Pasteurised or Tuberculin Tested Pasteurised milk were submitted
to the Laboratory for the Phosphatase test. All the samples tested
were reported as satisfactory.
Satisfactory reports were also received on all the 22 samples
of Sterilised milk or Tuberculin Tested Sterilised milk which were
subjected to the Turbidity Test at the Park Hospital Laboratory.
All the tests referred to above are now contained in the
Milk (Special Designations) Regulations, 1960.
The long standing practice of taking samples of milk in the
course of delivery to hospitals, schools, and institutions in the
early hours of the morning was continued. Sixteen samples of milk
so taken were submitted for chemical analysis to the Public Analyst,
and a further 13 samples were submitted to the Park Hospital
Laboratory for Phosphatase and Methylene Blue tests.
Periodical visits were made by the Public Health Inspectors
to the premises from which milk is distributed. The standard of
cleanliness and arrangements for the distribution of milk were
found to be satisfactory.
ICE-CREAM
By the end of the year there were 335 registered Ice-cream
premises in the Borough. The great majority of dealers sell only
pre-packed ice-cream, but there acre, however, four premises which
are also registered for the manufacture of ice-cream, and four
registered for the storage of ice-cream.
Before a dealer wishing to sell ice-cream can be registered
by the Council the premises are first inspected to ensure they are
suitable, and the Proprietor must comply with the requirements
relating to ice-cream contained in the Heat Treatment Regulations.
Regular inspections are made of all the premises where icecream
is sold, manufactured, or stored, and during the year two
