116 MILK HYGIENE 



Malet ^^ cites an example of a milk epidemic wherein 

 from August 21st to the 2d of September, 18 persons be- 

 longing to 11 households were attacked with scarlet 

 fever after drinking milk from a farm where there was 

 a scarlet fever patient.

 of desquamating scarlet fever. One was a child, aged 9, 

 the other a young man aged 19 who did the milking and 

 in other ways assisted in the dairy during his illness.

 and the severity of the attack appeared to depend upon 

 the quantity of the implicated milk consumed. ' ' 



London, 1901. The total number of cases was 293, all 

 resulting from one x)olluted milk source. " The out- 

 break occurred on the delivery course of a certain con- 

 tractor in London. He obtained milk from 38 farms. 

 On one of these farms there were four cases of scarlet 

 fever, the farmer, his wife, son and daughter. The cows 

 were healthy. " The cases were widely scattered in Lon- 

 don but were all directly traceable to milk from the im-
