=Inspection after Slaughter.=--The inspection after slaughter is of the utmost importance, not even second to that of the proper inspection during fattening and before slaughter. The veterinarian, skilled in his science, can tell by the inspection of the vital organs of the slaughtered animal whether it is affected with any organic disease. Among cattle the most frequent organic diseases are lumpy jaw and tuberculosis. In the case of swine one of the most common of diseases is trichinosis. In the latter case an inspection of the vital organs of the animal is not sufficient. The muscles of the swine, first and most commonly affected by trichinosis, must be examined microscopically in order to eliminate the possibility of the flesh of such animals going into commerce untagged or unnoticed. If the flesh of the swine impregnated with trichinosis be thoroughly cooked practically all of the danger to man is eliminated. The consumer, however, should not be subjected to the chance of imperfect cooking. A swine affected with trichinosis should either be refused admission into consumption or should be so tagged that the consumer should know the danger to which he is exposed in order to take the necessary precaution to safeguard his health. =Tuberculosis.=--There is a difference of opinion among veterinary and hygienic experts respecting the disposition which is to be made of carcasses affected with tuberculosis. It is claimed by some that if the tuberculosis is local, that is, does not extend beyond the lungs, there is no reason why the flesh of the animal should be refused to the consumer. The basis of this contention is founded upon the opinion of some of the most eminent veterinarians that bovine tuberculosis and human tuberculosis are entirely distinct diseases and cannot be transmitted either from the cow to man or vice versâ. It is not the province of this manual to decide this controversy, although it is only right that the consumer should be given the benefit of the doubt. Therefore, if the carcass of an animal affected with local tuberculosis is to be passed into consumption it should be plainly marked as the flesh of a tuberculosed animal,--not only the carcass as a whole, but every piece thereof that is introduced into consumption directly or after canning or mincing. The consumer is thus left free to choose for himself whether to eat such meat or not. There is a universal agreement among hygienists and veterinarians that where tuberculosis is generalized, that is, has affected practically all the organs of the body, the carcasses should be condemned. No one will take exceptions to this ruling, though it does not appear very plain to the ordinary consumer why a little tuberculosis is not a bad thing if a great deal of it is a very bad thing. There is an unfortunate tendency in many quarters to neglect minute effects and only pay attention to mass action. This does not seem to be a reasonable or desirable method of procedure.
