New Delhi: The Prime Minister has asked colleagues in the science ministries to decide on a time frame on testing the safety of Bt brinjal, the controversial first genetically modified food crop that is expected to hit Indian plates, said a person familiar with the matter. This was after he held a late evening consultation with three Union ministers, Sharad Pawar, Jairam Ramesh and Prithvi Raj Chavan. In a press statement, the PMO said that biotechnology is an important option for addressing food security and higher agricultural productivity. The PM held the meeting after differing opinions among his ministerial colleagues on who had the final say on clearing the genetically engineered vegetable. A bill to create an independent authority to attest the safety of the authority will be table in the ongoing Budget session but the current genetic engineering approval commitee is likely to have the final say on clearing transgenic food till 2012.
