Excerpt from Cattle Tuberculosis: A Practical Guide to the Farmer, Butcher, and Meat InspectorWhen the knowledge we have to-day as to the causation of the disease and of its effects is compared with that which was possessed ten years ago, it must be acknowledged that the advance has been immense.The majority of farmers and butchers then would probably have been mystified by the word 'tuberculosis, ' nor would medical officers of health have imagined that it was necessary to condemn the carcases of animals affected with the disease on the ground that there was a risk to the human subject of contracting the disease from the meat.During the interval the matter has been subjected, both on the scientific and practical side, to the close scrutiny of two Royal Commissions, and as a result of their investigations it is possible to show wherein the existing law requires to be relaxed and wherein it requires to be strengthened.It is now held that consumption in man and consumption in the lower animals is caused by the same bacillus, an organism belonging to the lowest form of vegetable life, and so small that in order to be properly examined it must be magnified four or five hundred times in all directions. When it gains access into the system, whether of animals or men - and in both it finds an entrance most readily into the lungs - it lives and multiplies on the tissues in such a way as to destroy their functions, and in the destructive process forming little lumps, or tubercles.' In man, as everyone knows, consumption of the lungs is by far the most common form in which the disease appears, and causes annually in England and Wales over deaths - more deaths, in fact, than is caused by any other disease. It is most fatal between the ages of fifteen and forty-five. This form cannot be shown to be caused by eating tuberculous meat or drinking tuberculous milk, but is due to the contagion spreading from man to man by the inhalation of dust to which is attached particles of dried sputum containing the tubercle bacillus. There are, however, many other forms in which the tubercle bacillus develops in man, and the most interesting of these, for our present purpose, is con sumption of the bowels, or tabes mesenterica.' This form occurs in children, and it is but reasonable to suppose that.About the PublisherForgotten Books publishes hundreds of thousands of rare and classic books.
