246 Principles of Legislative Milk Control. 



PRODUCTION OF RAW MILK. 

 Cow Stables. 



Requirements. 



1. They shall be used for no other purpose than for the keep- 

 ing of cows, and shall be light, well ventilated, and clean. 



2. They shall be ceiled overhead if there is a loft above. 



3. The floors shall be tight and sound. 



4. The gutters shall be water-tight. 



Recommendations. 



1. The window area shall be at least 2 square feet per 500 cubic feet of air space 

 and shall be uniformly distributed, if possible. If uniform distribution is impossible, 

 sufficient additional window area must be provided so that all portions of the barn shall 

 be adequately lighted. 



2. The amount of air space shall be at least 500 cubic feet per cow, and adequate 

 ventilation besides windows shall be provided. 



3. The walls and ceilings shall be whitewashed at least once every six months 

 unless the construction renders it unnecessary, and shall be kept free from cobwebs and 

 dirt. 



4. All manure shall be removed at least twice daily, and disposed of so as not to be 

 a source of danger to the milk either as furnishing a breeding place for flies or otherwise. 



5. Horse manure shall not be used in the cow stable for any purpose. 



Milk Room. 

 Requirements. 



Every milk farm shall be provided with a milk room that is 

 clean, light, and well screened. It shall be used for no other pur- 

 pose than for the cooling, bottling, and storage of milk and the 

 operations incident thereto. 



Recommendations. 



1. It shall have no direct connection with any stable or dwelling. 



2. The floors shall be of cement or other impervious material, properly graded and 

 drained. 



3. It shall be provided with a sterilizer unless the milk is sent to a bottling plant, 

 in which case the cans shall be sterilized at the plant. 



4. Cooling and storage tanks shall be drained and cleaned at least twice each week. 



5. All drains shall discharge at least 100 feet from any milk house or cow stable. 



Cows. 



Requirements. 



1. A physical examination of all cows shall be made at least 

 once every six months by a veterinarian approved by the health 

 authorities.
