In the colon, flesh foods rapidly undergo decomposition, giving rise to numerous poisons, which are absorbed into the blood, and are toxic to the nervous system, and cast an additional burden upon the liver and the kidneys. These are a sort of dietetic clinkers, which throw nature's delicate machinery out of adjustment, and produce various symptoms of auto-intoxication. Bouchard found that the fecal and urinary excrement of carnivorous animals is twice as poisonous when injected into rabbits as that from a herbivorous animal. The former also emits a strong odor, and the fecal discharges are offensively repulsive. Dr. Haig, before quoted, also asserts that "Bright's disease is the result of our meat-eating and tea-drinking habits; and as these habits are common, so also is the disease." _6. Tuberculosis, Ulcer, Cancer, and Appendicitis_ While it is true that tuberculosis is more frequently contracted through the use of tuberculous milk than from tuberculous meat, the latter source of infection cannot be ignored. Numerous cases of tuberculosis have been reported where the infection could be directly traced to the flesh of tuberculous animals. Dr. E. C. Shroeder, of the Bureau of Animal Industry of the United States Department of Agriculture, says: "That ten per cent of the dairy cattle in the United States are affected with tuberculosis impresses me as a very conservative estimate. In New York State, about thirty-three per cent of all cattle tested were found to be tuberculous." Dr. Julius Rosenberg, of New York City, writes: "Cattle tuberculosis is rapidly increasing. There is scarcely a dairy herd without a number of infected animals. It is an ever growing menace. The health department of Boston estimates the percentage of tuberculous animals producing the city's milk supply to be from twenty to twenty-five per cent. Conservative estimate places the number of cows dying yearly from tuberculosis at one million, were they permitted to die a natural death; but they are killed before drawing the last gasp, and served as prime beef." In one year in the United States, the entire carcasses of thirty-five thousand one hundred three cattle were condemned because of generalized tuberculosis. In the same year, a portion of the carcass of ninety-nine thousand seven hundred thirty-nine more were rejected because of local tuberculosis. Professor Ravenal, of the University of Wisconsin, says that of the thirty-five million hogs killed for food annually in the United States, seven million are found to be infected with tuberculosis. Some one has said that meat would sell for a dollar a pound if all the diseased meat were eliminated.
