test is not absolutely infallible, it is so far superior to 

 any and all other methods of diagnosis that it should

the milk. Foot and mouth disease is one wide spread 

 in European countries but which has not yet gained a 

 permanent foothold in this country. The ingestion of 

 the milk, which always contains the causal organism, 

 produces the disease in both humans and cattle. In the 

 human the disease is very similar to that in cattle; it 

 may end in death. Vesicles are produced in the mouth, 

 on the lips, nose and fingers. The causal organism, 

 which has not yet been demonstrated, may occur in 

 butter or cheese. It is easily destroyed by pasteurizing 

 the milk.
