Eight samples proved to be tuberculous. Five samples were
from supplies coming from Sussex, one from Surrey, one from
Kent, and one from a local farm. A considerable number of
cows were examined by the Authorities' Veterinary Officers, suspected
animals isolated, and samples taken. As the result of
their investigations two animals were dealt with under the Tuberculosis
Order, 1925, and in one case, while investigations were
being carried out, an outbreak of Foot and Mouth Disease
occurred, necessitating slaughter of the entire herd.
