Sampling.—Under provisions of the third Schedule to the first
of the above-mentioned Regulations, Methylene Blue and Phosphatase
tests have been prescribed, the former for assessing the
"keeping" qualities of milk and the latter for estimating the
efficiency of pasteurisation. In addition, a Turbidity test is also
prescribed for ascertaining the effectiveness of the heat treatment
of Sterilised milk. During the year 40 samples of milk, 37 of
Pasteurised and 3 of Sterilised, were submitted to these tests and
only one failed to reach the required standard. Particulars of this
sample were forwarded to the Ministry of Food for any action
considered necessary. A further sample was tested for "tubercle
bacilli" by the animal inoculation method and at the end of the
requisite period the animals wcro certified " free from tuberculosis."
