Sampling.—Under provisions of the third Schedule to the first
of the above-mentioned Regulations, Methylene Blue and Phosphates
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 38 samples of milk, 32 of pasteurised and 6 of
sterilised, were submitted to these tests. The samples, all of which
proved genuine, were obtained mainly from schools and hospitals.
Analytical Examination of Milk.—Five of the 22 formal and 32
informal milk samples submitted to chemical analysis proved nongenuine.
In the case of each non-genuine report the presence of up
to 1% added water was indicated. However, as the total solid
content was in fact greater than that legally required, it was considered
that the discrepancy was due to the normal seasonal decline
in milk-solids other than fat and the samples were regarded as
those of good milk.
Reports on samples taken from L.C.C. Schools and Nurseries
for chemical and bacteriological examination continued to be furnished
quarterly to that authority and reports on samples taken
from Hospitals in the Borough for similar purposes were again
forwarded to the authorities concerned.
