Sources of Meat
Cattle, sheep and swine form the principal source of meat, although horse flesh and even the flesh of dogs is used in some countries. From a hygienic or sanitary standpoint there are no particular objections to the use of horse or dog meat for food. Horse meat is very much coarser than either beef or pork; it does not have the same marble appearance and has a sickening odor. When properly prepared it is difficult to distinguish it from beef.
From a hygienic standpoint there are certain conditions which render the meat of animals unfit for food. They are: First, the death of animals from old age, dis-ease or accident; second, animals dying from injury, drugs, overwork or fright; third, animals that are too young.
