The Food Safety Standards Authority of India (FSSAI) has made it mandatory for the food and drugs department of every state to test for harmful bacteria like e coli in milk this year. This apart, the milk producers too will have to test for bacterial content like staphaureus and listeria monocytogenes before pushing it into the market. The new set of standards was first introduced across the nation in August 2011. The producers will have to declare on their packets that the milk is certified e coli, staphaureus and listeria monocytogenes free. The FSSAI has laid down standards for 10 types of milk that include buffalo, cow, goat or sheep, mixed, standardized, re-combined, toned, double-toned, skimmed and full-cream milk.
