traced in approximately two-thirds of the farms involved, and 13 cows were dealt
with under the Tuberculosis Order, 1938.
Two samples of tuberculin-tested milk (of which 75 completed samples were
taken) yielded a positive result, i.e., 2.6 per cent. As a result of investigation of
these two attested herds, a Guernsey cow was slaughtered under the T.B. Order,
1938, and the post-mortem revealed tuberculous lesions in the udder. Samples of
milk taken for biological tests from the remainder of the herd proved negative.
It has been found impossible to identify the source of infection of the other T.T.
sample; tuberculin tests of the herd have not revealed reactors, group samples
covering the herd were submitted to biological examination and subsequently
reported to be non-tuberculous. The farmer has, however, consistently contravened
the requirements of the Milk (Special Designations) Order, 1936, in respect of
labelling and sealing containers and his licence has been suspended. It was concluded
that some infection had been introduced, but no confirmation could be
obtained that supplemental milk had been added either at the farm or en route.
Accredited milk showed a ratio of 1.4 per cent., and ungraded milk 4.8 per
cent, positive, compared with 1.7 and 3 per cent., respectively, in 1943.
Venereal diseases
The work of the clinics included in the London and Home Counties Scheme
for the free diagnosis and treatment of venereal diseases has been carried on throughout
the year. Full facilities have been provided, but, owing to enemy air activity
and the consequent evacuation of part of the population, there has been a slight
decrease, compared with 1943, in the amount of work done. Towards the end of
the year, however, when enemy activity subsided, the attendances increased, and
were maintained at the original level.
