 Supplies. 



Milk is probably one of the most important foods we have. 

 The question of a pure milk supply is one of the hardest ques- 

 tions that a food governing or controlling body has to deal with. 

 It is often stated that milk comes very close to being a perfect 

 food for minute plant organisms which we call bacteria. At the 

 present time, people who study the cause of diseases find that 

 most of them are caused by bacteria. These plant bodies grow 

 very rapidly in milk. 



There are thousands of places where milk can become con- 

 taminated ; hundreds of thousands of farms produce milk, every 

 one of these places is a source at which these bacteria can enter 

 into the milk, and if the milk is not kept cool during the entire 

 trip from the producer to the consumer, they greatly increase 

 in number. 



The food controlling body has a very hard problem to deal 

 with. Also there is probably no food produced which can be so 

 easily adulterated as can milk. It is a perfectly easy thing to 

 skim a little of the cream off of the top of a can of milk. Also 

 it is a perfectly easy thing to add a little water to milk. The 

 baggage charge is just as much for a can of milk or for a milk
