Placing an indefinite moratorium on the commercial release of Bt Brinjal, which would otherwise have been the first genetically modified food crop in India, Environment Minister Jairam Ramesh Tuesday said he took the ”precautionary approach” as there was no clear consensus on the subject among Indian scientists. ”Impose a moratorium on the release of Bt Brinjal till such time that independent scientific studies establish satisfaction of both public and professionals, the safety of the product from the point of view of long-term impact on human health and environment,” Ramesh said at a press conference here.
