Sutton Coldfleld, 1891 {February-April). 



Total number of cases . . 40 



Deaths 5 



Cases amongst drinkers of sus- 

 pected milk — " almost without 

 exception." 



Circufnstances implicating the milk 

 supply. — One cow presented char- 

 acteristics similar to those at Hendon 

 — recent calving, emaciation, ulcer- 

 ation on teats, eruption and desquam- 

 ation. A second cow slight similar 

 symptoms. All the 17 houses first 

 invaded took the implicated milk. 

 The outbreak consisted of two " ex- 

 plosions," coinciding in time with the 

 ulceration and eruptive conditions of 

 the first cow. After sale of milk had 

 been stopped, outbreak ceased. 



Apparent exciting cause. — (?) Cow 

 disease.

Circumstances itnplicatittg the milk 

 supply. — Sanitary conditions of dairy 

 and farm good. The exciting cause 

 was not definitely ascertained, but 

 some of the cows had abraded teats, 

 boils on the udder, or vesicular scabs. 

 Y)r Klein failed to discover any strepto- 



coccus corresponding with that in the 

 case of the Hendon disease. 



This outbreak was limited to 8 

 days and to two sanitary districts, 

 every one of the cases being cus- 

 tomers of the one dairyman. The 

 disease was more largely incident on 

 better class houses taking most milk. 

 Confirmatory evidence implicating the 

 milk came from the Essex village 

 where the dairy-farm was situated. 

 Here the only two houses invaded 

 were two to which the milk in 

 question was delivered — except that 

 one girl fell ill who had opportunities 

 of helping herself to the milk. In 

 dairyman's own family the infant fed 

 on " nursery " milk from his own cow 

 escaped ; his little daughter drinking 

 the Essex milk sickened with scarlet 

 fever. 



Apparent exciting cause. — (?) Cow 

 disease.
