PROVISION AS TO MILK SUPPLY.
During the year 295 samples of ordinary milk were procured
and submitted to examination for tuberculosis in accordance with
the Milk and Dairies (Consolidation) Act, 1915.
These samples were taken as follows:—
Samples taken at cowsheds in the Borough 18
Samples in course of delivery from country cowsheds
to local dairymen and purveyors of milk
in the Borough 49
Samples taken at dairymen's premises in the
Borough 111
Samples taken in course of delivery by local
dairymen or milk sellers on their rounds in
different parts of the Borough 117
295
Eight samples proved to be tuberculous. Five samples were
from supplies coming from Kent, one from Surrey, and two from
local farms. A considerable number of cows were examined by
the Authorities' Veterinary Officers, suspected animals isolated,
and samples taken. As the result of their investigations four
animals were dealt with under the Tuberculosis Order, 1925.
The following Table summarises the results of the bacteriological
examination of ordinary milk samples, taken under the
