SECTIONAL TRANSACTIONS.—M. 577 
Mr. W. Goppen and Dr. J. BLackwoop.—The nutritional aspect 
(10.30). 
Dr. N. C. Wricut.—Some implications of compulsory pasteurisation 
(10.50). 
Apart from the relation of pasteurisation to the reduction of milk-borne 
disease and to the nutritive value of milk, certain other factors must be 
taken into account in deciding whether a policy of compulsory pasteurisa- 
tion for city milk supplies is justifiable. Such factors include the effect of 
compulsory pasteurisation on the producer-retailer and the small distributor ; 
the influence of pasteurisation on the production of clean milk and on the 
eradication of bovine disease ; its effect on wholesale and retail milk prices ; 
and, finally, the expediency of applying an element of positive compulsion 
to the artificial treatment of such a widely consumed foodstuff as milk. 
These factors are discussed in the present communication. 
Mr. Ben Davies.—The problem from the point of view of the dairy 
industry (11.10). 
Prof. G. S. Witson.—The necessity for a safe milk supply (11.30). 
Milk is a valuable food, and so far as its nutritive properties are concerned 
it is not an expensive food. Its importance in infant feeding, its power to 
stimulate the growth of under-nourished school children, and its value in 
the treatment of disease, amply justify for it a very special place in the 
human dietary. Unfortunately, however, owing to the fact that it is par- 
ticularly liable to become infected, and that it furnishes an admirable 
medium for the multiplication of many types of pathogenic bacteria, its 
use in the raw state is bound to be accompanied by a certain amount of 
danger to the human population. While the production of clean milk 
from healthy animals may diminish this risk to some extent, it can never 
entirely eliminate it. To do this, the only satisfactory measure at the 
moment is some form of heat treatment that will destroy all pathogenic 
aka while interfering to a minimal degree with the nutritive value of 
the milk. 
Discussion (11.50). (Dr. H. D. Kay, Miss OLGA NETHERSOLE.)
