 employed, but the important question to the consumer is the character of the raw materials used, the sanitary conditions which attended their preparation, and their freedom from admixtures of other meats cheaper in price and of different dietetic values.

Adulteration of Canned Fresh Meat.—Fortunately the process of sterilization is of such a character, when properly carried out, as to exclude all necessity for the addition of any preservative substances to canned fresh meat. The use of ordinary condimental substances in moderate quantities cannot be regarded as an adulteration. Hence, the addition of small quantities of salt, sugar, vinegar, and the ordinary spices, when used solely for the improvement of the taste and flavor and not for preservative purposes, is regarded as unobjectionable.

The common preservatives used in canned meat are, first, those which give color to the meat and preserve its natural red tint. For this purpose saltpeter and sulfite of soda are most commonly employed. Red dyes of any description are rarely, if ever, found. The preservative which is used most frequently in canned meat is borax or boric acid. That this use is not necessary is evident from the investigations which have been made in the Bureau of Chemistry which show that in most cases no preservatives at all are used. The addition of any chemical preservative is, therefore, to be regarded as unnecessary and as an adulteration.

The use of any diseased, tainted, decomposed, or filthy meat, even if it is of the same origin as that in the can, is an adulteration of the most serious character and which can only be effectually controlled by the inspection mentioned above. The adulteration of the meat of fowls of all descriptions by cheaper meats, such as pork or veal, even if they be of wholesome and sound character, is an adulteration said to be often practiced and one which it is difficult to detect if the particles of meat are finely comminuted.

Standard for Preserved Meats.—The standard for preserved meat is the same as that for fresh meat which is given in the Appendix (Circular 19, Office of Secretary, Department of Agriculture). The meat must be sound, wholesome, clean, freshly taken from the slaughtered animal, and not one that has died from disease, suffocation, or otherwise, and must conform in name and character to the meat of the animal.

Frequency of Adulteration.—The examination made of numerous samples of canned meat in the Bureau of Chemistry shows that the adulteration of these foods is rather common but by no means general.

Canned Horse Meat.—Horse meat is commonly used for human food in many European countries, although it is believed that it is not used to any extent in the United States. When procured from healthy animals in a proper way there is no hygienic objection to its use, though it is considered to be somewhat tougher than the flesh of other animals more commonly employed as food,
