Milk has been an important part of the human diet for thousands of years. It is a great source of both a variety of vitamins and minerals that are required for a good health. Milk provides a whole range of nutrients essential to growth and development. Thus milk makes a significant contribution to our diets.
But, there are a number of points along the value chain where the quality and safety may be compromised. For example, the quality of milk from one cow in Assam of India is affected badly. Natural milk of a cow has 1.8% of fat, at the dairy farm the same milk's fat increased to 3.6%. Similarly, at the farm and vendor, water is added by 6% which is actually zero per cent when produced from a cow.
However, Dairy accounts for 20% of India's agricultural economy. About 70% of rural population is involved in milk production in someway. In 2012, a study found that majority of samples either watered down or contaminated with potentially toxic agents like detergents and other chemicals.
