The grey shades of the white revolution of india

Milk and dairy product adulteration is a very serious issue taking place mostly in developing and third world countries all around the world. Instances of this have been seen in India for a long time now. In a nationwide studyconducted by the FSSAI (food safety regulatory authority of India), it was observed that 68.7% milk and milk products sold in our country is not regulated or certified by the government bodies. Out of this 82.6% products are adulterated in one form or the other. Adulteration can be due to natural or man-made. Natural adulteration may happen due to un-hygienic milking processes and man-made adulteration is an intentional chemical additives usage for diverse malicious reasons.

What is adulteration?
Adulteration is the addition of some chemical substances to a product to increase its quality and quantity. It not only takes into account the addition and removal but also contamination taking place during the growth, storage or transport of the item. Adulterated food is dangerous because it may be toxic and can affect health and it could deprive nutrients essential for proper growth and development.

How is cow’s milk adulterated?
Cow’s milk is adulterated at different stages:-
Farmer level: – Cheap commercial fodder bought by farmers is adulterated with toxic chemicals; also growth hormones are used to raise cows to boost their milk yields. In remote areas, a lot of problems are also caused by poor sanitary and hygiene conditions in which the cow is raised, kept and milked:

  • According to a survey 1 out of 2 cows are affected by mastitis which results in pus in milk.
  • 9 out of 10 samples contain E.coli due to fecal contamination.
  • Urea is added to the milk to provide whiteness to the milk.
  • Detergent is used to emulsify the oils in the milk.

Unorganized Dairy: – The unorganized dairy sector consisting of your local milk dairies buy milk from local farmers; as these farmers have no proper cold storage equipment or processing units, they add formalin and hydrogen peroxide to extend its shelf life. Furthermore, the detergents used to wash the containers in which the milk is transported also contaminate the milk. More often than not, they add significant water to the milk to enhance the overall volume of sales.

Commercial Milk Brands: – They get milk from the agents or middlemen and add skimmed milk powder to it to make different variants which are then packed and sold. Also adulteration happens in different formats by adding chemicals and preservatives to give an unnatural boost to the shelf life of packaged milk. Many brands are also found to add harmful chemicals/preservatives to milk to increase its shelf life in the absence of refrigeration facilities across old format retail stores.
