UK farm ministry finds GM presence in rapeseed LONDON, April 12 (Reuters) - Britain's Agriculture Ministry said on Thursday it had discovered genetically modified (GM) material in two trial rapeseed crops, which would be swiftly destroyed. A small quantity of imported spring rapeseed had tested positive for a promoter that could indicate genetic modification, and tests on a hybrid winter rapeseed variety had shown levels of GM presence, the ministry said in a statement. ``Neither of these varieties are being grown commercially in the UK,'' it said, adding that the first crop would be destroyed by spraying and the other would be cut down. Public opinion in Britain has turned against GM foods after a string of high-profile food scares, including mad cow disease. Many restaurants and shops advertise that they do no sell GM foods. The government's GM crop trials have been criticised by environmentalists, who say Britain is risking contaminating the rest of its countryside.
