It generally becomes contaminated in handling and processing. Therefore, if it is not properly stored and treated, the microorganisms grow rapidly and spoil and make it unsafe for human consumption. Besides, some microorganisms are used in the manufacture of various milk-products such as cheese, butter etc.
