There were no refusals or revocations of licences under the Milk (Special Designations) Order
1923, during the year.
Thirteen samples of designated milks were examined during the year. All of these were
satisfactory.
Forty-eight samples of milk (including two "Certified," one "Pasteurised" and two "Grade
A (T.T.)") were taken during the year for examination for the presence of tubercle bacilli under
the Milk and Dairies (Consilidation) Act, 1915.
Six samples (Nos. 0/356, 0/359, 0/374, 0/376, 0/377 and 0/381), representing 12.5 per cent.
of the total number sampled, were found to contain tubercle bacilli, and action was taken resulting
in an examination of the herds at the supplying farms situate in the counties of Buckinghamshire (4),
Leicestershire (1), Bedfordshire (1).
The other 42 samples showed no evidence of tuberculosis.
The following are particulars of the six positive samples:—
0/356.—Two cows individually sampled. Microscopical examination showed the presence of
excess of cells and a notice restricting the sale from these cows served. Animal inoculation
tests revealed no tubercle infection.
0/359.—Samples of milk collected from the whole of the herd belonging to the producer proved
on biological examination to be negative. Cow sent to the knacker prior to the veterinary
inspection of the herd apparently the culprit.
0/374.—"Bulk" sample of milk contained living tubercle. Miscroscopical report of one cow,
individually sampled, stated acid fast bacilli were found. This cow was slaughtered.
Animal inoculation test of all the other samples taken proved negative.
0/376.—Investigations made by the County Council's Veterinary Surgeon, but the source of the
tubercle found in the sample remains undiscovered. A number of "bulk" samples
were taken and also samples from two individual animals which proved negatives.
0/377.—Herd examined by a Veterinary Surgeon and two cows were individually sampled, in
addition to "bulk" sample being taken from the remainder, all of which proved
negative. It is probable that an old cow in the herd when the milk was sampled by
this Authority was responsible for the infection. This cow was disposed of for slaughter
at the time investigations at the farm commenced.
0/381.—Herd examined by Veterinary Surgeon and certain individual samples were taken.
In addition a "bulk" sample was taken from the remainder of the herd. One of the
cows individually sampled was made a subject of a Detention Notice under the provision
of the Tuberculosis Order, and has since been slaughtered. The post-mortem certificate
indicated that this animal was suffering from Tuberculosis of the Udder—not an advanced
case.
Meat Inspection.—The Inspectors visit the slaughter-houses at the times set apart for
slaughtering and examine the carcases and organs for evidence of disease. Shops and stalls are
also kept under close observation.
The number of private slaughter-houses in use in the area at the dates mentioned was:
