CLEAN MILK 153 



Location, construction, lighting, and ventilation of stalks and 

 other buildings 



Buildings in which certified milk is produced or handled shall 

 be located where good drainage can be secured and at sufficient 

 distance from other buildings, dusty roads, cultivated and dusty 

 fields, and other possible sources of contamination, to avoid dirt, 

 dust, or odors from such places. 



Stables shall be constructed so as to favor the comfort of the 

 cows. The floors shall be of cement or an equally non-absorbent 

 material, and sloped to provide drainage. Stall floors may be 

 constructed of sound plank well laid on cement. 



The inside surf ace of the walls and all ulterior construction shall 

 be smooth, with tight joints, and capable of shedding water. The 

 ceiling shall be of smooth material and dust-tight. All horizontal 

 and slanting surfaces which might harbor dust shall be avoided 

 as far as possible. 



The stable shall be as well lighted as the average house, and 

 shall have an average of at least six feet of transparent window 

 glass for each animal, with as much sunlight as possible and the 

 light evenly distributed. 



The ventilation shall be so efficient that one will not notice a 

 stale, disagreeable, or strong odor on entering the building at any 

 time. 



Mangers and water troughs shall be constructed of iron, ce- 

 ment, or other equally non-absorbent material, properly sloped 

 to provide good drainage. 



All necessary measures shall be taken to prevent the entrance 

 of flies and other insects, as well as rats and mice and other vermin 

 in the stable or dairy buildings. 



There shall be no cellar underneath a cow stable. The stable 

 shall contain not less than five hundred cubic feet of air space per 

 cow. 



Condition of the stable in which the milk is dravm 



The stable shall be kept scrupulously clean. Interior walls 

 should be light in color. The walls and ceiling shall be white- 

 washed often enough to keep them clean and white and at least 

 twice a year, unless such walls and ceiling are of smooth cement
