Union Minister of State for Commerce Jairam Ramesh has asked the Directorate-General of Foreign Trade (DGFT) to explain reports that imported genetically modified (GM) food products were entering Indian supermarkets and food chains unchecked. The move came after representatives of the Centre for Sustainable Agriculture (CSA) and the Greenpeace-India met him here on Wednesday and cautioned about food products imported into India with soya, corn, canola and cottonseed ingredients from GM-producing countries that have no provision for labelling GM products as different from non-GM products.
