Length of Storage.—The question of how long meat can be safely kept in cold storage of this kind is one which has not been decided. It may be said, however, that the period should not be extended any longer than is necessary and that the consumers of meat should be provided in ordinary times, if transportation is undisturbed, with practically fresh meat. It is evident that if the principal meat-packing centers are Chicago, Omaha, and Kansas City the cities and parts of the country remote from these localities must have meat somewhat older than those which are near by. If we pass to distant countries, as for instance, Europe, where fresh meats are received from the United States or even from Australia, the time elapsing between slaughter and consumption must necessarily be long. Thus the length of time in which meat should be left in cold storage after it is properly matured depends upon its geographic distribution and is not a matter to be decided arbitrarily.
When meats are not only kept in cold storage for transportation but are actually frozen, as is often the case, they can, of course, be kept for a much longer time than when subjected merely to a low temperature at or slightly above the freezing point. For this reason meats that are to be carried to a long distance and not to be consumed for a long time after preparation are usually frozen and kept so during transport.
Effect of Low Temperature on Enzymic Action.—Attention has been called to the fact that low temperature does not inhibit enzymic action, and, therefore, it must be admitted that this continued activity must gradually deteriorate the quality of the product. The question, therefore, which is the most important is not how long can meat be kept in a frozen condition but how short a time must it be kept. In all cases, therefore, of this kind the consumer is entitled to know the length of time during which his meat has been kept frozen, and this desirable condition of affairs is easily secured by the necessary local, state, and national inspection already mentioned.
Disposition of Fragments Arising From the Dressing of Beef.—It is evident that the fragments of sound, wholesome meat which is dressed for delivery to commerce are themselves edible and hence there can be no hygienic or other objection to preparations made from these fragments, such as sausage and other minced and comminuted meats which appear upon the market. In other words, the consumer is entitled to know that because a piece of meat is comminuted is no reason for supposing that it is not edible.
Sausage, mince meat, comminuted meat, potted, canned, and other meats or preparations from these sound, clean, edible fragments, necessarily rejected in the process of preparing fresh meats for curing and for consumption, are entitled to the same consideration and may be looked upon with the same certainty of purity by the consumer when properly inspected and prepared as the larger pieces.
