A DECISION to allow genetically modified canola to be grown in Victoria has inflamed dissent in the Brumby Government and sparked warnings that non-GM farms could be contaminated. Anti-GM activists have also lashed the decision, saying consumers face a growing array of food made from GM material — without always knowing when they are buying it. But the move was welcomed by rural interests as sensible, and backed by scientists who say the risks of adverse consequences are minimal.
