MILK INSPECTION 223 



6. — Helpers Other Than Milkers. 



All persons engaged in the stable and dairy should be reliable and 

 intelligent. Children under twelve years should not be allowed in the 

 stable during milking, since in their ignorance they may do harm, and 

 from their liability to contagious diseases they are more apt than older 

 persons to transmit them through the milk. 



7. — Small Animals. 



Cats and dogs must be excluded from the stables during the time 

 of milking. 



8.— The Milk. 



All milk from cows sixty days before and ten days after calving 

 must be rejected. The first few streams from each teat should be 

 discarded, in order to free the milk ducts from milk that has remained 

 in them for some time and in which bacteria are sure to have multi- 

 plied greatly. If in any milking a part of the milk is bloody or stringy 

 or unnatural in appearance, the whole quantity of milk yielded by that 

 animal must be rejected. If any accident occurs in which a pail be- 

 comes dirty, or the milk in a pail becomes dirty, do not try to remove 

 the dirt by straining, but put aside the pail, and do not use the milk for 

 bottling, and use a clean pail. 



Remove the milk of each cow from the stable immediately after it 

 is obtained to a clean room and strain through a sterilized strainer of 

 cheesecloth and absorbent cotton. 



The rapid cooling is a matter of great importance. The milk 

 should be cooled to 45 ° F. within an hour and not allowed to rise above 

 that as long as it is in the hands of producer or dealer. In order to 

 assist in the rapid cooling, the bottles should be cold before the milk is 

 put into them. 



Aeration of milk beyond that obtained in milking is unnecessary. 



9. — Utensils. 



All utensils should be as simple in construction as possible and so 

 made that they may be thoroughly sterilized before each using.
