Sample No. D/62 was taken from a large multiple firm, from which a number of samples had
been taken and found to be below the required standard.
This matter was reported to the Health Committee who authorised the Medical Officer to place
the facts before the Minister of Health.
The Medical Officer of Health sent a letter to the Ministry of Health setting out the facts.
In consequence of this letter an interview took place between the Medical Officer of Health and a
representative of the Ministry of Health, the result of which was duly reported to the Health
Committee. No further action was taken.
Sample No. D/71 was taken from a multiple firm and reported upon to the Health Committee.
This matter automatically solved itself by reason of the License expiring at the end of the year.
Forty-eight samples of milk were taken during the year for examination for the presence of
Tubercle Bacilli under the Milk and Dairies (Consolidation) Act, 1915. Three samples (Nos. 0/120,
0/128 and 0/140) were found to contain Tubercle Bacilli and action was taken resulting in the examination
of the herds at the supplying farms.
In the case of sample No. 0/120, a cow was slaughtered under the Tuberculosis Order. The
post-mortem examination showed that the animal was affected with tuberculosis (not being advanced
tuberculosis within the meaning of the Order).
In the case of sample No. 0/128, a cow was slaughtered under the Tuberculosis Order. The
post-mortem examination showed that the animal was suffering from advanced tuberculosis.
In the case of sample No. 0/140, samples of milk were taken from 2 suspicious animals at the
farm, both suffering from slight induration of one quarter of the udder. Biological examination
showed both samples to be negative. A further inspection of the farm was made by the Veterinary
Inspector, who found no cows shewing any clinical symptoms that suggested they might be giving
tuberculous milk. He reported that the farmer had 5 cows dried off since original sample was taken,
but all of these cows looked well. A further sample was taken by this Authority from the retailer
which proved to be negative.
In 44 instances the result of the examination proved negative.
In one instance the guinea-pig inoculated with the sample of milk succumbed to an acute
infection by some organism contained in the milk other than the Tubercle Bacillus. It was therefore
impossible to say whether this sample did or did not contain Tubercle Bacilli. A further sample
from the same source was therefore obtained and submitted for examination.
Public Health (Prevention of Tuberculosis) Regulations, 1925.—No case was dealt
with under the above Regulations during 1929.
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:—
