SUNDAY TELEGRAPH(LONDON) October 10, 1999: International: US alarm grows over GM foods Congressmen call for labelling by DAVID WASTELL in Washington AMERICAN consumers are finally waking up to the international controversy over genetically modified food, with members of Congress joining a growing clamour for compulsory labelling and leading companies searching for alternative ingredients for some products. In a country where 70 per cent of the items on supermarket shelves have some kind of GM content, there are signs that American shoppers are gradually taking up the concerns over GM food that have swept Britain and Europe. With half of American corn and one third of its soya beans containing transplanted genes, most of the country's best-known household products would be at risk if a consumer backlash took hold - from Coca-Cola to tomato ketchup, breakfast cereals to cake mixes. Until recently, most American consumers were oblivious to the fact that they routinely eat and drink artificially-altered combinations of genes. But recent publicity, including last week's high-profile climbdown by the American company Monsanto on plans to insert a so-called "terminator gene" into its cornseed, is leading to a sharp increase in awareness. It has led to farmers across America's corn-growing heartlands wondering whether the bumper crops they are harvesting - at least half of them from genetically - -engineered seed - will be worth growing in the same form again. A Gallup poll published in America last week surprised many in the food industry by finding that 68 per cent of adults surveyed wanted labelling of food that contained GM ingredients.
