Milk float

“ Therefore, in producing certified milk, only the cleanest water available is allowed to be used in the dairy. Impure water is a common source of the contamination of milk in such places. On some farms, the water supply comes from a well that is too near the barn or that is too shallow to avoid being made impure by the germs that filter into it from the barnyard or a cesspool. If vessels in which milk is placed are washed in such water, it is necessary to sterilize them by boiling or steaming before milk is put into them, in order to kill the germs that come from the water. ”

“ The effect is bad on all kinds of livestock, especially on fattening animals and dairy cattle. “Feeders” must have an abundance of water to fatten quickly. Insufficient water cuts down the quantity of milk given by dairy cows. Lack of enough exercise further decreases the yield. An occasional trip through this mud to the trough, so cakes the cows’ udders with dirt that the milker wastes valuable time in washing them—and they must be washed, if one would have clean, wholesome milk. ”

“ The milk, as fast as drawn, should be removed from the place of milking, lest it absorb odors from the droppings, the breath, or the exhalations from the cow's body—or even from the sweat and grime of the person and clothes of the milker—for milk is extremely sensitive to these influences. It is much more so than is popularly supposed, and should be put in a sweet atmosphere as soon as possible when drawn. Fine fancy goods, with the most delicious and delicate flavor, cannot be made from milk that has been exposed to the influence of a foul atmosphere. ”

“ It is well to remember, however, that water is an adulteration just the same as formaldehyde and perhaps more pernicious, since the quantities of the latter are so small in an ordinary quantity of milk as not to make a great deal of difference except in the feeding of invalids and children, while watered milk is a swindle not only to the pocketbook but to the body also, since the requisite nutritive value is lacking. ”

“ Sewage-emanations and other gases, paint, metallic matters, &c., are all readily taken up by milk. Hence the absolute necessity for seeing that when milk is received into our homes, it is stored in a safe and sanitary position. Milk should never be stored in metallic vessels in the first place; and it should not be kept in cupboards or other receptacles which are situated in the neighbourhood of sinks, closets, or open drains. Too frequently, such carelessness in the home-treatment of the milk-supply leads to illness, which is all the more serious, because its origin is unsuspected. ”

“ Uncleanliness in milking not only gets filth into the milk, but taints and injures its flavor. Some, for this reason, recommend washing the cow's bag before milking. But if this washing is done with cold water by the milker, it is quite likely to consume time, cool the bag and cause the cow to hold up a portion of the mess. Experience shows that the quicker the milk can be drawn, after the operation is commenced, the better the yield. If washing is done, it should be with warm or tepid water, and be the work of one person, who should go through the whole dairy in advance of the milkers. ”

“ Payne narrates the case of a woman suffering under a nervous affection whose milk, two hours after an attack of the disease, became viscid, like the white of an egg. Similarly, a deterioration and consequent alteration in properties is induced in the milk of the cow if she be over driven, exhausted, or harassed. The food of the animal likewise exercises an influence on the quality of its milk; thus when cows are fed on turnips, wormwood, decayed leaves, and plants of the cabbage or onion families, the flavour of these substances is imparted to their milk. ”

“ This will make milk abundant at all seasons of the year, and plenty wherever we choose to carry it. It will also save the lives of thousands of children, in cities, that are fed on unwholesome milk or poisonous mixtures. There is no temptation to adulterate such milk, for the process of condensation is cheaper than any mixture that could be passed. ”

“ I have no doubt from what you say, that your cows are kept in the cow-house during the night, and only turned out during the day, as this would account for the difference in the quantity of milk. But such a mode of management, though it saves trouble to the dairy-maid, who finds it much easier to milk the cows in the cow-house than in the open field, is bad for both the cows and the dairy; as the cows, after feeding on grass all day, cannot of course relish dry food at night, and [Pg 310] whenever they fast unnaturally very little milk is secreted. ”

“ When milk is allowed to stand for some time exposed to warmth and air, a spontaneous coagulation occurs, caused by fermentative changes in the sugar of milk, by which it is converted into lactic acid through the action of germs.
Milk is sometimes adulterated by water, the removal of more or less of the cream, or the addition of some foreign substance to increase its density.
The quality of milk is more or less influenced by the food upon which the animal is fed. Watery milk may be produced by feeding a cow upon sloppy food.
The milk of diseased animals should never be used for food. ”

“ She must have water handy, instead of away back in some retired corner of a large pasture, as she naturally wants to drink a few swallows quite often, in warm weather, but will go until she gets excessively dry and feverish before she will travel a long distance to get water. When thus very dry, she drinks an inordinate quantity, which makes her feel heavy and uncomfortable—and whatever annoys a cow lessens the flow and reduces the quality of the milk. ”

“ Aliments rich in fat and sugar favor the production of butter, and augment the supply of milk. Locust-beans, malt, and molasses are good milk-producing foods; but the chief condition in the production of milk rich in butter is simply that the animals which yield it must be fed with abundance of nutritious food. Nor must it be supposed that the richness of milk is due to the smallness of the yield, for whenever the quality of the secretion is inferior, it is almost certain to be deficient in quantity. ”

“ A careful mother will clean the bottle, which serves to carry the food for the baby. The farmer thinks his duty is done if he washes the milk pails and other utensils with ordinary cold water. The water is sometimes obtained from wells situated in dangerous proximity to the outhouse, or from streams which carry sewage from neighboring farms or settlements. After washing the receiving pails in a careless manner there is enough milk left in them to cause disagreeable odors, but, nevertheless, the fresh milk is drawn into these vessels. ”

“ In order to modify or “humanize” cow’s milk so as to make its composition nearly the same as that of mother’s milk, simple dilution with water is therefore not sufficient.
There are, however, various other methods which may be used to advantage. For instance, top-milk from a bottle of fresh milk which has stood 4 or 6 hours in ice water will contain 6 to 8% of fat. By diluting this with an equal part of water, the percentage of protein, fat and mineral matter will be about right, and sugar, either cane-sugar or milk-sugar, may be added to supply the carbohydrates. ”

“ However, the whole-grain and liquid-milk method works well only when the birds are on a good, green range and is practical to use only when milk products are cheap. Some loss from pendulous crops is to be expected when liquid milk is consumed liberally and this is one of the chief objections to its use. The milk receptacles should be set on a wire screen and covered to protect them from the weather and from contamination with droppings. Sanitation is especially important when milk is used. ”

“ On being traced out, these cases are usually found to have been supplied with milk from one and the same source. When the surroundings of the dairy or farm are inspected, sewage-contamination is usually found. Leakage of drains into a water-supply is a common occurrence; and as this infected water is used in cleansing the milk-vessels, the origin of the epidemic is clearly enough accounted for. In some cases, dairies have been found to be constructed in a thoroughly insanitary manner, and cleanliness—the first condition where milk is concerned—is by no means always observed. ”

“ Such milk will be among regular supplies for armies and navies, and for all shipping to distant countries. All cities and villages may have pure, cheap milk, as the condensation will render transportation so cheap that milk can be sent from any part of the country where it is most plenty and cheapest. ”

“ The milk is therefore heated as soon as it is withdrawn from the animal; and, when warm, it is poured into a large skin bottle, with which the poorest hut is furnished, and in which there is always a remnant of sour milk sufficient to sour the new milk, after it has been stirred with a stick kept for the purpose. Those bottles are never washed or cleaned: they are therefore always incrusted with cheese and dirt, and the smell admitted by them is sufficient to show what they contain. But it is precisely in this that the secret for making the milk undergo the vinous fermentation consists. ”

“ Neither the cheese, rennet, or cheesepress, must be suffered to contract any taint; nor should the churns be scalded in the dairy, as the steam arising from the hot water tends greatly to injure the milk. The utensils of the dairy should all be made of wood: lead, copper, and brass are poisonous, and cast iron gives a disagreeable taste to the productions of the dairy. Milk leads in particular should be utterly abolished, and well-glazed earthen pans used in their stead. Sour milk has a corroding tendency, and the well known effects of the poison of lead are, bodily debility, palsy, and death. ”

“ Milk absorbs odors very quickly, therefore should never be left in a refrigerator with stale cheese, ham, vegetables, etc., unless in an air-tight jar. It should never be left exposed in a sick room or near waste pipes. Absolute cleanliness is necessary for the preservation of milk; vessels in which it is to be kept must be thoroughly scalded with boiling water, not merely washed out with warm water. ”

“ The cow must be kept carefully cleaned, particularly the udder, and so must the hands of the milker, and the pail which holds the milk. "The habit of some milkers of wetting their hands with milk just as they begin is a filthy practice and the cause of much bad milk and poor butter." There must be no hidden, inaccessible places in the pails, nor must rusty tinware be used, because it imparts a metallic flavor to the milk. ”

“ Of five hundred dairies near New York and Brooklyn, all, except five or six, feed their cows on distillery slops. And the reason is, that it yields more milk at a cheaper rate than any other food. But it soon destroys the health of the animals, and after most of their fluids are, by this process, changed to unhealthy milk, and the cows become diseased, they are sent to a cattle market and a new supply obtained. ”

“ When we study more carefully the effect upon the milk of the different species of bacteria found in the dairy, we find that there is a great variety of changes which they produce when they are allowed to grow in milk. The dairyman experiences many troubles with his milk. It sometimes curdles without becoming acid. Sometimes it becomes bitter, or acquires an unpleasant "tainted" taste, or, again, a "soapy" taste. Occasionally a dairyman finds his milk becoming slimy, instead of souring and curdling in the normal fashion. ”

“ If she does not readily drink it, teach her by keeping her a few days without an ample supply of water. Take care that nothing is given her which will injure the taste of the milk, such as turnips and parsnips. Carrots are a fine vegetable for cows. Have her milked by a person who understands the process, or she will not give it freely, and will soon become dry. But the most abundant supply of the richest milk will avail little, unless all the articles used in the care of it are kept in perfect order. ”

“ On dairy farms probably milk is next choice as a bait to cane-molasses solution, considering its convenience. The addition of ripe bananas or other fruit increases the attractiveness of the milk bait. The curd from milk, with one-half pound of brown sugar added for each pound, and water to make it thoroughly moist, is a very good bait and continues to be attractive for 10 days or longer if Kept moist. A mash consisting of one-half pound of bran, 1 quart of milk, 1 quart of water, 2 tablespoonfuls of brown sugar, and a yeast cake makes an attractive and lasting bait. ”

“ Until within recent years in the cities and at present in smaller towns, milk is largely retailed from cans which are carried on the wagons or are kept in stores. This exposes the milk to contamination from street dust and from the container furnished by the consumer. It is well recognized that every utensil with which milk is brought in contact adds more or less bacteria to it, and the less milk is handled, the better will be its condition when it reaches the consumer. ”

“ But even frost does not kill the bacteria. If milk which has been kept sweet or at the desired degree of sourness by cooling is allowed to get warm again, the bacteria which have been kept dormant will get a fresh start. For this reason milk and cream for city supply should not only be cooled strongly, but must be kept thoroughly chilled up to the time they are used, which means that they should be delivered cool to the consumer, and kept on ice in the house, never being allowed to warm up until used. ”
