CONTAMINATED MILK.
In 1902 I instituted a system of taking samples of milk upon arrival at
City Railway Stations with a view to determining to what extent the milk
distributed in London could be regarded as an active agent in the spread of
Tuberculosis.
Since 1902 these investigations have been continued in the years 1904,
1905, 1906, 1907, 1908, 1909 and 1910, and with each succeeding year it
becomes more apparent that until the hands of the farmer, dairymen and
others sending milk to London are forced by Statute, no real lasting improvement
can be looked for in the character of the milk supply.
The milk taken during the present year represents the supply from the
following counties:—
Essex. Norfolk.
Hertfordshire. Suffolk.
Derbyshire. Huntingdonshire.
Kent. Cambridgeshire.
Buckinghamshire.
In all 42 samples were submitted to Dr. Klein for bacteriological examination,
and his report thereon is as follows:—
