Woman's Institute Library of Cookery Volume II Part 2

If milk purchased in bottles is clean, there should be no sediment in the bottom of the bottle after it has been allowed to stand for some time. Also, if it is fresh, it will not sour quickly after it is delivered, so that in case it is properly cared for and sours quickly, it may be known to be stale milk. However, if it does not sour in the normal length of time, it should be looked on with suspicion, for, as has been pointed out, such milk may have added to it a preservative to prevent souring. The housewife may expect milk that is delivered cold and is guaranteed to be sanitary and fresh to remain sweet at least 24 hours, provided, of course, it is placed in the refrigerator immediately upon delivery and kept there until used.

CARE OF MILK

50. NECESSITY FOR CARE IN THE HOME.--If milk of good quality is bought, and, as has been suggested, this should be done whenever it is possible, the next thing to do is to care for it in such a way that it may be fed to the family in the same condition as it was when delivered. It is, of course, of prime importance that the dairyman deliver clean fresh milk, but this is not sufficient; the milk must remain in this condition until it is used, and this can occur only when the housewife knows how to care for it properly after it enters the home. It is possible to make safe milk unsafe and unsafe milk positively dangerous unless the housewife understands how to care for milk and puts into practice what she knows concerning this matter. Indeed, some of the blame laid to the careless handling of milk by dairymen really belongs to housewives, for very often they do not take care of milk in the right way after delivery. As too much attention cannot be given to this matter, explicit directions are here outlined, with the idea of a.s.sisting the housewife in this matter as much as possible.

51. KEEPING MILK CLEAN IN THE HOME.--Immediately upon delivery, the bottle containing the milk should be placed in the coolest place available, never being allowed to stand on the porch in the sun or where such animals as cats or dogs may come in contact with it. When the milk is to be used, the paper cap should be carefully wiped before it is removed from the bottle, so that any dirt that may be on top will not fall into the milk. If not all the milk is used and the bottle must be returned to the cool place where it is kept, it should be covered by means of an inverted drinking gla.s.s or, as shown in Fig. 6, by a gla.s.s or porcelain cover. Such covers, or _sanitary milk_ _caps_, as they are called, are very convenient for this purpose and may be purchased at a slight cost.

52. Another precaution that should be taken is never to mix stale milk with fresh milk, because the entire quant.i.ty will become sour in the same length of time as the stale milk would. Also, milk that has been poured into a pitcher or any other open vessel and allowed to stand exposed to the air for some time should never be put back into the bottle with the remaining milk. Such milk is sure to be contaminated with the germs that are always present in the dust constantly circulating in the air. It is sometimes necessary to keep milk in a vessel other than the bottle in which it is delivered. In such an event, the vessel that is used should be washed thoroughly, boiled in clean water, and cooled before the milk is poured into it.
