Ports in India face an enormous burden in scientifically analysing products from countries growing genetically modified crops. No GM organisms can be imported unless sanctioned by the Genetic Engineering Approval Committee, the nodal agency that functions under the Ministry of Environments and Forests. Only two food imports have been approved, according to an MoEF response to an RTI submission: refined vegetable soybean oil and crude degummed soybean oil by Catholic Relief Services and Care India as food aid in 2002. But a couple of weeks ago, packets of Doritos potato chips available in select supermarkets, including in Chennai, were revealed to contain two strains of GM corn.
