CHAPTEE XXI 



MACHINERY AND PKOGEDURES TO OBTAIN A PURE MILK SUPPLY 



In various chapters, particularly in Chapter XVI., existing 

 defects in the conditions of milk supply have been pointed out, 

 and the requirements of a pure supply indicated. Innumer- 

 able scientific papers condemning the existing state of affairs 

 have been written. Health Congress after Health Congress has 

 passed resolutions in favour of a cleaner and purer milk supply, 

 and learned committees have considered the subject and framed 

 admirable rules and regulations as to what is required. The 

 practical results have been meagre. It is safe to say that the 

 milk supply to-day is nearly if not quite as infected with 

 tubercle bacilli as it was ten or twenty years ago. Milk as sup- 

 plied may be a little less dirty and bacteria laden than it was 

 ten to twenty years ago, but the average improvement has been 

 trifling. Epidemics of infectious disease spread by milk are 

 still regularly and frequently recorded in the scientific press. 

 On the chemical side preservatives have been for the most 

 part eliminated, but milk adulteration and cream abstraction 

 is still very much with us ; it is merely changing its character, 

 and instead of being coarse and crude is becoming scientific 

 and a matter of toning. Clearly the milk problem is not 

 becoming any less of a problem, and our available legal 

 enactments conspicuously fail to provide the consumer with 

 pure milk. The present chapter is devoted to a broad general 

 consideration of the administrative machinery and procedures 

 required to obtain a pure clean milk supply. 



In considering this problem of a pure milk it must be 

 remembered that there are four separate requirements, and 

 pure milk implies the following :
