All samples were systematically tested for the presence of pre—
servatives and colouring matter. In no case, however, was a posi—
tive result obtained.
Milk sampling was carried out on 5 Sundays during the year,
and 26 samples were purchased for analysis on these occasions.
Samples of milk in course of delivery by wholesale firms to the
number of 55 were taken during the year. Most of these samples
were taken at Clapham Junction or South Lambeth (G.W.) Railway
Stations. Samples of milk to the number of 87 were taken in
course of delivery to hospitals and elementary schools in the
borough. In addition 15 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 permit 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 8 milk purveyors in regard to 24 samples of milk
all of which were reported by the Public Analyst to be genuine.
Proceedings with regard to adulteration were taken in 4
instances—fat abstraction, 3 ; extraneous water, 1, particulars
relating to which will be found set out in the tables on pages 66
and 67.
Condensed Milk.
Of the 13 samples of full-cream condensed milk submitted to
the Public Analyst during the year, 5 (2 of which were formal
samples) were reported against as containing a percentage of milk
fat below 9 per cent., the minimum amount required under the
Public Health (Condensed Milk) Regulations, 1923 and 1927.
Proceedings were instituted in regard to the 2 formal samples,
the result being set out on pages 66 and 67. In one case warranty
was pleaded, but unsuccessfully.
