168 THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 

 QUESTION 2. Is pasteurisation commercially practicable? 



ANSWERS. 



Pasteurization is commercially practicable, but investigations made by the 

 Bureau of Animal Industry show that it is not always reliable when left 

 entirely to the dealers. Commercial pasteurization in order to be reliable 

 should be under official supervision. (Chief Bureau of Animal Industry.)
