THE MILK SITUATION IN THE DISTRICT OF COLUMBIA. 169 



It has no injurious effect. (Surgeon General U. S. Army.) 



It slightly alters the nutritive as well as digestive qualities of milk. (Sur- 

 geon General U. S. Navy.) 



If properly performed there is no proof that it has any deleterious effect on 

 the nutritive and digestive qualities of milk. (Surgeon General Public Health 

 and Marine-Hospital Service.) 



Very slight effect at 140 to 145. (Dr. William H. Park, New York, N. Y.) 



Efficient pasteurization at the temperatures indicated does not destroy the 

 digestive enzymes or nutritive principles in milk. (Dr. Henry L. Coit, Newark, 

 N. J.) 



At above temperature (140 F. for 40 minutes) none. (Dr. R. G. Freeman 

 New York, N. Y.) 



It is doubtful if any change is caused. Some individuals do not thrive on 

 pasteurized milk, but same is true of raw milk. (Dr. M. P. Ravenel, Madison 

 Wis.) 



No harmful effect whatever if done below 155. (Dr. C. E. A. Winslow 

 New York, N. Y.) 



Detrimental. (Health officer Ann Arbor, Mich.) 



I think it has no effect. (Health officer Baltimore, Md.) 



There is much difference of opinion on this subject, some authorities claim- 

 ing that it makes milk harder to digest, especially for infants and young 

 children. (Health officer Birmingham, Ala.) 



Less nutrition and harder to digest. (Health officer Bismarck, N. Dak.) 



Probably none if properly done. (Health officer Cleveland, Ohio.) 



Mooted question. (Health officer Columbus, Ohio.) 



Practically none. (Health officer Detroit, Mich.) 



None if milk is not heated over 140 F. (Health officer Jacksonville, Fla.) 



Has not been definitely decided. (Health officer Kansas City, Mo.) 



The effect on digestibility is bad. (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.) 



So slight that amounts to nothing. (Health officer Providence, R. I.) 



In itself, properly conducted, pasteurization probably has no effect on either. 

 Commercial pasteurization, however, may affect both and it also encourages 

 neglect of the care necessary to provide wholesome, safe milk. (Health officer 

 Richmond, Va.) 



Probably slightly retards digestion. (Health officer Rochester, N. Y.) 



No one knows, so far as my knowledge goes. Opinions differ, although I 

 believe the concensus of opinion is that it is slightly harder for infants to 

 digest. One man says one thing and another another. (Health officer Seattle, 

 Wash.) 



The vitality of milk is destroyed. (Health officer Syracuse, N. Y.) 



None. (Health officer Topeka, Kans.) 



None. (Straus Laboratory, Washington, D. C.) 



It destroys the two most valuable nutritive qualities in the milk, namely, 

 albumen and lactic acid. ( Sharon Dairy, District of Columbia. ) 



From my experience with my own children, I never found that raw milk 

 agrees better with them than pasteurized milk. (Dairy Machinery & Construc- 

 tion Co., Derby, Conn.) 



If properly pasteurized at 145 F., there would be no difference. (Creamery 

 Package Manufacturing Co., Chicago, 111.) 



Do not think that enough data has been collected to give us any positive data 

 in regard to the nutritive or digestive value of milk after pasteurization com- 

 pared with before, authorities disagreeing on this pont. (Borden's Condensed 

 Milk Co., New York, N. Y.) 



I am told by a number of competent physicians that pasteurization destroys 

 the self-digesting ferments or enzymes, and diminishes the nutritive value of 

 milk. ( Walker-Gorden Laboratory, Washington, D. C.) 



Slightly diminishes it. (Dr. V. C. Vaughan, Ann Arbor, Mich.) 



A much debated question. Apparently it is a question of the individual. 

 (Dr. S. C. Prescott, Boston, Mass.) 



Very little effect. (Health officer Los Angeles, Cal.) 



If carried on at low temperatures, no effect. (J. M. Houston, White Cross 

 Milk Co., Washington, D. C.) 



Decreases same. (Health officer San Francisco, Cal.) 



These are very important questions, and can hardly be answered in the space 

 you allow. (Health officer Wheeling, W. Va.)
