CERTIFIED MILK
Immediately after leaving the cow, the milk should be cooled to at least 45 F. It should at once be put into bottles that have been previously sterilized and then be tightly covered, and should be kept in ice water until ready for consumption. No matter how carefully the milk is handled, it is infected with many bacteria, but if it is quickly cooled, the increase of the bacteria is greatly retarded. Under no circumstances buy milk from a grocery store out of a large can. Go to your health officer and encourage him in his campaign for sanitary dairies and certified milk.
Such milk as we have described under the head of sanitary dairies, when it has been tested by the board of health and has received the approval of the medical profession, is known as "certified milk;" and, although the price is usually fifteen to twenty cents a quart, when compared with the cost of baby's illness it will prove to be cheaper than the dirty milk which sickens and kills the little folks.
There is no doubt that the increased use of "certified milk" has been a great factor in the reduction of deaths from infant diarrhea in recent years.
