THE PASTEURIZATION OF MILK 



places, the emphasis is upon physical regulations 

 and inspections, with occasional laboratory tests to 

 confirm the conclusions reached and to aid in the 

 discovery of obscure defects which may escape ob- 

 servation during the usual inspections. No advice 

 can be given as to which method is most desirable 

 without first knowing local conditions, taking into 

 account the extent of the milk industry, the avail- 

 able factors of men, money and laboratory equip- 

 ment, etc. Each community presents its individ- 

 ual problem. 



Health authorities are often requested by milk 

 dealers to give advice as to the form of pasteurizing 

 apparatus which will perform the best work, or 

 they are asked what kind of machine the authorities 

 recommend. It is manifestly improper for health 

 authorities to recommend specifically any one or 

 more forms of apparatus as the best. If they did, 

 they would lay themselves open to the charge of 

 unfair favoritism, and to the suspicion that im- 

 proper influence determined their judgment. It 

 is only proper that they should state that in their 

 experience certain forms of apparatus, operated 

 in certain ways, have performed certain things in 

 actual practice which are or are not satisfactory
