—The composition of the flesh of pigs has been given in detail for two reasons. First, because the data relative to this point are much more complete than those of any other flesh product and were obtained in a more systematic way. In the second place, pork is one of the chief meat products of the United States,—the industry being one of great magnitude, and pork being a common article of diet among all classes of people. Further than this, the data indicate the general character of fresh meat, and illustrate as well as that of any of the typical animals the nutritive value and properties of flesh. The study of pork, therefore, may be regarded as a typical study of meat products. It is quite as important that all people should be informed respecting the nature of the wholesome meat which they consume and its value as a diet as it is that they should be certain these meats be procured from healthy animals and in a sanitary way. These two classes of knowledge together give a complete scheme of information which the consumers in this and other countries are entitled to have.

Pork, by many hygienists, is regarded as the least desirable of meat products, and it is not the purpose here to combat that idea. Granting, however, for the sake of argument, that pork is a less desirable meat food than those derived from cattle or sheep, that is all the more reason for knowing particularly everything connected with it. Modern investigations have appeared to establish the fact that swine are less subject to those forms of disease, with the exception of trichinosis, which tend to infect the meat and make it unfit for consumption than cattle or sheep. The diseases to which swine are usually subject act quickly, as a rule, and are speedily fatal, as in the case of hog cholera, whereas the diseases most to be feared in cattle and sheep are those of slow activity and those of a nature which is often not revealed until slaughter, namely, tubercular diseases. In so far, therefore, as infection from disease is concerned, previous to slaughter, it appears that the flesh of swine is less objectionable and less open to suspicion than that of cattle or sheep. One of the chief objections to the use of pork in any form, whether fresh or cured, has been based upon the unsanitary habits of the animals themselves. With the modern methods of cleanliness and care, however, the conditions under which the pigs grow and fatten are, or should be, quite as sanitary as those surrounding cattle and sheep. The consumer, of course, has the right to insist upon such sanitary conditions and these, under present laws or those which are to be enacted, will doubtless be supplied. It is believed that in this country sanitary environments and a sanitary method of feeding will develop types of animals superior to those grown in other countries, where the population is denser and where the facilities for the proper growth and fattening of the animal are less abundant. It is hoped that the general diffusion of knowledge respecting all food products among our people will aid greatly in securing these very desirable results.
