96 MILK HYGIENE 



came from a herd in which a cow with mastitis was 

 found, and it was explained that her secretion had been 

 mixed with the common supply that very day. 



2. Prof. Hoist has also reported the following cases : 

 Five persons were attacked with acute catarrh of the 

 stomach and intestines a couple of hours after drinking 

 milk from the same milk shop. The milk came from a 

 herd in which a case of inflammation of the udder, 

 caused by streptococci, was discovered by special inves- 

 tigation. Here, also, it was shown that mastitis secretion 

 had been mixed on the same day with the other milk, 

 through the mistake of a new servant. 



3. Dr. Johnnesen observed, likewise in Christiana, 

 two cases of diarrhoea (mother and child) which began 

 two hours after the use of raw milk which contained 

 numerous diplococci and streptococci. The examination 

 of a herd that had furnished the milk revealed that two 

 cows suffered with inflammation of the udder, and in 

 their secretion these cocci were found. Apparently still 

 other cases arose from the use of the same milk, but 

 these were not investigated closely. 



4. Four children of one family were attacked with 

 acute catarrh of the stomach and intestines, also a child 

 of another family. The disease, in both cases, was 

 traced to the same milk. This appeared by superficial 

 examination to be normal, but by microscopic examina- 

 tion it was shown to be rich in diplo- and streptococci. 

 Here, also, it appeared with practical certainty that the 

 harmful quality of the milk was derived from a case of 

 mastitis. 



5. In Stockholm 14 the members of nine families be- 

 came ill with the following symptoms: fever, languor, 

 faintness, nausea, vomiting and diarrhoea, together with
