MILK SUPPLY. In the area there are 31 promises
registered for the retail sale of pro-packed supplies. There
are six large purveyors of milk - one has premises in the
district for the storage of milk only.
Other than a small quantity of certified farm bottled
milk, all the milk retailed is heat-treated.
There were 75 samples of milk submitted to Methylene
Blue Reduction Test, with phosphatase examination, of which
6 were reported unsatisfactory. the unsatisfactory samples
occurred during the hot summer weather.
A further 72 samples of milk were submitted for
biological examination. Seventy were reported free from
tuberculosis. In one instance the sample bottle was broken
in transit and in another case the guinea-pig died prematurely.
