58. Milk strainers should be kept clean ; scalded a sec-

 from the City of New York. 



Water Supply. 



60. The water supply used in the dairy and for wash- 

 ing utensils should be absolutely free from any contam- 

 ination, sufficiently abundant for all purposes, and easy 

 to access. 



61. This supply should be protected against flood or 

 surface drainage. 



62. The privy should be located not nearer than 100 

 feet of the source of the water supply, or else be pro- 

 vided with a water-tight box that can be readily removed 

 and cleaned, and so constructed that at no time will the 

 contents overflow or saturate the surrounding ground. 



63. The source of the water supply should be rendered 

 safe against contamination by having no stable, barn- 

 yard, pile of manure or other source of contamination 

 located within 200 feet of it.
