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 58 samples of milk consisting of 47 Pasteurised
milks, 2 Sterilised and 9 T.T. Pasteurised were examined in accordance
with the prescribed tests and, with the exception of one sample
of pasteurised milk, all proved to be satisfactory.
In connection with the unsatisfactory sample, the producers
were warned and further samples taken. These samples subsequently
proved to be satisfactory.
Analytical Examination of Milk.—All designated milks being
sold in the Borough were sampled, including those of the super-fatted
variety, viz., Channel Island, Jersey, South Devon, etc. A total of
49 samples, 24 formal and 25 informal, were submitted to chemical
analysis and, with the exception of an informal sample of Channel
Island milk, all proved to be genuine.
There was a slight deficiency of milk fat in this sample of
Channel Island milk and investigation revealed that the deficiency
was due to insufficient mixing at the dairy, a fault which the producer
was instructed to remedy.
Six samples of cream (one synthetic) were sampled and found
to be genuine.
Summaries of samples taken from L.C.C. Schools and Nurseries
for chemical and bacteriological examination continued to be
furnished regularly to that authority.
