 Hospital Service.) 



Between 140 and 158 F. ; 140 to 145 F. for 20 minutes approved. (Dr.

At 140 F. for 40 minutes, 155 F. for 30 minutes, 167 F, for 20 minutes,

 New York, N. Y.) 



At 150 F. (Health officer Ann Arbor, Mich.) 



We have tried pasteurization in Atlanta, Ga., and have found it worse than 

 bad. For a city of this size we do not think it should be considered. (Health 

 officer, Atlanta, Ga.) 



Not over 158 F. (Health officer Baltimore, Md.) 



At 162 to 165 F. (Health officer Birmingham Ala.)

 half hour. (Health officer Cleveland, Ohio.)

At 140 to 145 F. for 20 minutes, not above 150 F. (Health officer Detroit,

Holding the temperature of milk 20 minutes at a temperature of 150 to 160 

 F., not a mere flash as some plants do. (Health officer Kansas City, Mo.) 



Only suspicious milk should be pasteurized. Pasteurization is done by 

 dirty dairies because dirty milk will soon sour. It is best to have a clean 

 dairy and not pasteurize. At 165 to 170 F. (Health officer Lynchburg, Va.) 



Look up any authority on pasteurization. Our information is from these 

 authorities rather than from experience. (Health officer Montclair, N. J.)

At 158 F. and kept at this temperature for 20 minutes. (Health officer 

 Providence, R. I.)

 milk sterile. (Sharon Dairy, District of Columbia.) 



Our Mr. Willman is the inventor of the pasteurizing process of heating milk 

 continuously for 30 minutes at between 145 to 150 F. We have mentioned 

 above that the Government is recommending this process, therefore we have 

 nothing else to add. (Dairy Machinery & Construction Co., Derby, Conn.)
