All samples were systematically tested for the presence of preservatives.
In no case, however, was a positive result obtained.
Milk sampling was carried out on 17 Sundays during the year,
and 102 samples were purchased for analysis on these occasions.
Samples of milk in course of delivery by wholesale firms to the
number of 73 were taken during the year. The bulk of these
samples was taken at Clapham Junction or South Lambeth
Railway Stations. Samples of milk to the number of 77 were
taken in course of delivery to elementary schools in the borough.
Sixteen samples were also taken in course of delivery at the
request of the Medical Officers of Health of neighbouring boroughs
under the provisions of the Milk and Dairies (Consolidation) Act,
1915, which permits the vendor to require (within 60 hours) the
Council to take samples from a corresponding delivery or milking.
Proceedings with regard to adulteration were taken in 26
instances—fat abstraction, 6; extraneous water, 19 (one of these
containing added colouring matter); added colouring matter 1—
particulars relating to which will be found set out in the tables
on pages 66 to 68. Warranty was pleaded in defence in one case
and was successful.
