PLATE 5. (a) HOME PASTEURIZER 



When reliable pasteurized milk cannot bs obtained, milk may be pasteurized 

 in the home, for infant-feeding, by means of this apparatus, or even with 

 ordinary kitchen utensils (see p. 109). A still readier means of safety is 

 simply to heat the milk to boiling. Effective home heating ensures that 

 no infection enter the household by medium of milk, and illustrates private 

 prophylaxis as opposed to public prevention. The latter, however, affords 

 general protection, while the private process, even when adopted, may be 

 inefficiently performed. (Courtesy of the New York Milk Committee and

(6) RESULTS OF CLARIFICATION 



The two bottles on the left show sediment and slime removed from milk of 

 cows with normal udders, by the clarifier. The two bottles on the right 

 show sediment and slime removed by the clarifier from the milk of two 

 cows with sore udders, which caused a septic sore throat outbreak of 

 669 cases, with 14 deaths. (Courtesy of the New York Milk Committee
