DAIRYING 71 



790. Market Milk is a term used to distinguish milk sold 

 directly to the consumer either wholesale or retail in cans or in 

 bottles from milk sold in cans to creameries, cheese factories and 

 condensaries. 



Some years ago an estimate was made of the number of cows 

 supplying milk for different purposes in the United States. This 

 estimate divided the milk production as follows: 

 7,600,000 cows produce the market milk. 

 9,700,000 cows produce the milk for butter. 

 800,000 cows produce the milk for. cheese. 



791. Certified Milk. The use of the word "certified" as 

 applied to milk is limited by law in some states to milk from cows 

 and dairies that are regularly inspected by a representative of a 

 board of health or a medical milk commission. A certificate of 

 inspection is given to the owner or manager of a dairy furnishing 

 such milk. 



Milk commissions may be formed for the purpose of supplying 

 milk conforming to certain conditions and the commission may 

 make contracts to supply the consumer with such milk and to find 

 out if each producer has the necessary equipment and is capable 

 of living up to the required conditions ; a certificate is sometimes 

 issued with each bottle of milk sold. 



Some of the conditions under which certified milk must be 

 produced are the following: 



792. The cows, the stable, the feed, and the milkers must 

 always be up to the highest standard of health and cleanliness. 



The water used at the dairy must be examined by a chemist 

 and by a bacteriologist. 



The milk must not be more than twelve hours old when sold 

 and contain less than 10,000 bacteria in one cubic centimeter. 



The milk must be sold in sterilized bottles and kept at 50 F. 

 or lower until delivered to the consumer. 



793. These and other conditions that protect the purity of 

 milk can easily be provided without excessively expensive build- 

 ings and equipment. Some dairymen are now doing this as is 

 shown by a record kept by a man producing 250 quarts of milk
