During 5 years, 1927.31, 59.6 per cent, of these genuine
samples of milk contained over 3.5 per cent, of fat. In the following
5 years, 1932.6, this had increased to 62.9 per cent., and in 1936
was 70.7 per cent.
All samples were systematically tested for the presence of preservatives
and colouring matter but with negative results.
Milk sampling was carried out on 5 Sundays during the year,
and 25 samples were purchased for analysis on these occasions.
Samples of milk in course of delivery by wholesale firms to the
number of 23 were taken during the year. Thirty-five samples of
milk were also taken in course of delivery to hospitals and elementary
schools in the Borough, all of which were certified to be genuine.
The supply of milk to hospitals and institutions is kept under
careful supervision and samples are periodically taken for chemical
and bacteriological analysis.
During the year 16 samples of milk were taken for bacteriological
examination. Of these 15 were of pasteurised milk and 1
of ungraded milk. The last mentioned sample was tested for the
tubercle bacillus but with negative result. The results of the bacteriological
examination showed that all the samples complied with
the requirements.
Six samples were taken in course of delivery during the year
at the request of the Medical Officers of Health of neighbouring
Boroughs under the provisions of Sees. 21 and 29 and the second
schedule of the Food and Drugs (Adulteration) Act, 1928, which
permits the vendor to require (within 60 hours) the Council to
take samples from a corresponding delivery or milking. During
the year advantage was also taken of these provisions by 6 Battersea
milk purveyors in regard to 17 samples of milk.
Proceedings with regard to adulteration were taken in three
instances, particulars relating to which will be found set out in
the table on page 83.
