CHAPTER VIII 



THE SANITARY CONDITION OF MILK 



74. Unwholesome Milk. By the sanitary condi- 

 tion of milk is meant its condition as to wholesome- 

 ness for either food purposes direct or for manufac- 

 ture into butter or cheese. Milks that are in the 

 best sanitary condition are also those most suitable 

 for butter and cheese making ; milk that is not suit- 

 able for food should not be used for dairy purposes. 

 Milks are most frequently unsound because of dis- 

 eased conditions of the animals or because of the 

 presence of dirt and filth of various descriptions due 

 to lack of care of the animals or of the dairy utensils. 

 The spread of contagious diseases is often due to 

 unsound milk, where disease germs find lodg- 

 ment, readily undergo propagation, and are then 

 disseminated. 



75. Factors influencing the Sanitary Condition of 

 Milk. The factors which influence the sanitary 

 condition or wholesomeness of milk are : 



1. Condition of the animals as to health. 



2. Care of the animals. 



3. Care of the milk and dairy utensils. 



4. Food and water which the animals receive.
