SANITARY DAIRIES. 14! 



These special dairies have the dairy buildings constructed 

 with plenty of air and plenty of light, and with particular 

 attention directed to the sanitary conditions for the cows. 

 The cows themselves are tended with extreme care and kept 

 in an irreproachable condition of purity. The attendants 

 are kept under the most strict regulations. Special atten- 

 tion is given to the cleaning and. the sterilizing of the milk 

 vessels, and, indeed, every precaution is adopted, which sci- 

 ence and experience has suggested. The result is that milk 

 from such dairies is far cleaner than that of the common 

 supply. By the use of the precautions adopted the number 

 of bacteria in the fresh milk is reduced to a very low point, 

 the milk from such dairies having at most only a few hundred 

 bacteria per c.c., and frequently less than this. Such milk 

 can be preserved for a much longer period than ordinary 

 milk. If kept cool it may be preserved from souring for 

 many days, and, indeed, in some cases, the milk may be 

 kept in an apparently good condition for several weeks. In 

 such dairies it is expected that a strict veterinary oversight 

 should be given to the cattle to prevent the use of diseased 

 animals in the dairy herd, and exceptional care is taken to 

 prevent the milk from secondary contamination with infec- 

 tious material from any source. 



The milk from such special dairies is as reliable as care 

 can make it. But even such care does not remove all danger. 

 In at least one instance milk from such a well-kept dairy 

 has been, with considerable certainty, accused of distributing 

 diphtheria. But the chance of such a trouble arising from 

 " sanitary milk," is very much less than from the ordinary 

 milk supply, and, in general, the milk is of a far better quality 

 and more thoroughly reliable. 



Such dairies commonly sell their milk under special names, 

 with a special brand upon the milk bottles, and they must 

 of course obtain a higher price than ordinary dealers. The
