Theobald Smith.' 7 1907. expressed the opinion that pasteurization 
is the inevitable outcome of the future. He says : 
It seems to me that the real difficulty of the present condition is the trans- 
mission of specific disease germs which are not easily controlled by any amount 
of cleanliness, and these specific disease germs, one and all of them, may he 
destroyed by the average pasteurization. 
Sedgwick b voices the opinion of many sanitarians when he states 
that. 
when all is said and done, I agree with Professor Smith that we have got to 
pasteurize milk. Cooked milk is the only safe milk and always will remain 
the only safe milk for the use of mankind. Little by little the idea is spread- 
ing that raw milk is apt to be dangerous milk. 
Theoretically, pasteurization should not be necessary; practically, 
we find it forced upon us. The heating* of milk has certain disad- 
vantages which must be given consideration, but it effectually pre- 
vents much disease and death, especially in infants during the sum- 
mer months.
