Milk sampling. A total of 36 samples of milk (32 formal, 4 informal) were
submitted to the Public Analyst for chemical examination. All samples were
satisfactory. For average solids in all samples, excluding Channel Islands milk,
the figures were: Pat 3.5; Non-fatty solids 8.65.
Of the 65 samples of designated milk (47 pasteurised; 6 tuberculin tested
pasteurised; 7 tuberculin tested; and 5 sterilised) submitted to the Phosphatase,
Methylene Blue and Turbidity tests as appropriate, 2 samples of tuberculin tested
Paw Milk failed the Methylene Blue test. Since the milk was produced outside the
Borough, the appropriate Licensing Authority was informed. All other samples were
satisfactory.
Milk delivered to Schools and other London County Council Establishments. Of
the 34 samples of milk taken on delivery at London County Council Establishments,
17 were submitted for chemical and 17 for bacteriological examination. All samples
were reported to be satisfactory.
Oxidising Agents. The Milk and Dairies Regulations, 1949, provide for the
use of certain cleansing agents for milk containers and plant. All these products
are required to contain a small percentage of sodium chlorate to act as a detector
of the efficiency of subsequent rinsing. Pour samples were tested for the presence
of chlorates and were found to be free.
Ice cream.
Close supervision is exercised in connection with the manufacture, sale and
storage of ice cream, Premises, plant and refrigerators were kept under constant
observation. Pull and free consultation has taken place between manufacturers
and the Council's Pood Inspector on problems of production.
