THIRTY-EIGHTH ANNUAL CONVENTION 179 



Keep Milk as Cool as Possible. 



The colder milk is kept the longer it will keep. Bacteria 

 are responsible for the changes which take place in milk, and 

 bacteria increase in numbers very slowly at low temperatures. 

 Therefore, do not leave milk where it will get warm. If possible 

 put milk directly against the ice. If this cannot be done, put it in 

 the compartment of the ice box directly beneath the ice, for 

 the air circulating through the ice chest is coldest directly after 

 it passes over the ice. If no ice box is used, keep the milk as cool 

 as possible by putting it in the cellar, or by wrapping the bottle 

 in a damp cloth and setting it out of the direct sunlight in a cur- 

 rent of air. 



Keep Milk Away From Odors. 



Milk absorbs odors very easily, and so it should not be placed 

 in the same compartment with onions, or strawberries, or other 

 food having marked odors. 



Keep the refrigerator very clean and see that the drain pipe 

 and the shelf which catches the drip from the ice are kept free 

 from slime. Brushes are made especially for cleaning the drain 

 pipes of ice boxes. 



Milk that is kept covered absorbs odors less easily than that 

 which is not. Keep the cap on the milk bottle while it is in the 

 ice box unless the cap is torn or dirty, in which case a tumbler or 

 cup may be inverted over the mouth of the bottle. 



Wipe Off the Cap and Neck of the Bottle Before Opening It. 



The top of the milk bottle is exposed to dirt, dust and flies 

 during transportation, and has been handled, moreover, by the 

 driver, whose hands cannot well be kept clean while he is on the 

 route. For these reasons the cap and neck of the bottle should be 

 carefully wiped ofT with a clean cloth before the cap is removed. 



Care of Milk Bottles. 



Milk bottles, after being emptied, should be washed first in 

 cold and then in warm water. Fill the bottle half full of water,
