A row erupted in Tamil Nadu after the Food Safety and Standards Authority of India (FSSAI) directed a state-run brand to use the Hindi word ‘dahi’ on a curd (yoghurt) packet. The Tamil Nadu Cooperative Milk Producers Federation, popularly known as Aavin, their brand name, has refused to use the Hindi term in its printed label on the sachets and said that it would stick to the Tamil word 'tayir' to denote the product.?
