whilst union^ tho^e \vlio do use the milk or llesh, the proportion of 

 humanity suffering with tuberculosis increases almost in the same 

 ratio as the quantity per head per annum used. Hence the u;ieat 

 and urgent necessity ot" having all dairy and butchers' stock under 

 regular, constant and capable inspection. Xot only should the 

 be inspected at regular intervals, but all the surroundings where 

 stock are kept should be constantly inspected, and in any place 

 where proper precautions are not taken no milk should be allowed 

 to be used for human consumption ; and not only should the stock 

 and the premises be under constant supervision, but the persons who 

 milk the cows should be inspected also, to see that they are not 

 suffering from any skin or other infectious disease, and severe 

 punishment should in all cases be meted out to any person milking 

 or having anything to do with the preparing of the milk, suffering 

 from any disease. Milk is at the same time one of the most useful 

 and also" one of the most dangerous articles of human food, and it 

 is the duty ol the state to see that its people are protected from the 

 ignorance and carelessness of those who sell milk or its products in 

 any form.

The most common sources of infection are : Keeping or milking 

 animals in close, ill-ventilated sheds where the atmosphere becomes 

 fairly saturated with germs of all kinds, good and bad, the latter 

 often greatly out-numbering the former. 



Dirty cow-yards, where manure is allowed to accumulate, and 

 where the drainage is deficient or non-existent, compelling cows to 

 feed on unhealthy pastures, or allowing them to drink impure 

 water, are all sources of infection. How can pure milk be obtained 

 from cattle allowed to wander about the suburbs drinking stagnant 

 drainage water and eating all kinds of refuse.
