Green group urges EU ban on Aventis gene corn BRUSSELS, April 27 (Reuters) - Friends of the Earth (FoE) called on Friday on the European Union to ban one of the few gene-modified (GM) food products allowed to be used in the bloc, claiming it had not been proven to be safe. The environment group said a pesticide-resistant maize strain manufactured by Franco-German group Aventis (AVE.N) (AVE.PA) should never have been permitted for cultivation and use in the EU because scientific tests were insufficient to show it posed no risk to health or the environment -- a claim denied by Aventis. FoE said the maize, marketed as a feed crop, had only been fed to chickens during testing and not cows and pigs, which are the most likely to be fed the corn and which have very different digestive systems. A study at Britain's Bristol University, commissioned by FoE, found the chicken test to be scientifically unsound. FoE said other research submitted by the company when it applied for authorisation was equally unconvincing. FoE campaigner Adrian Bebb told Reuters, ``Consumers have had a gut feeling that things are not right and this confirms that they have been right about GM foods.'' Aventis rejected FoE's claim, saying the studies cited by the group were only a small part of the evidence it provided to show its maize was safe. Tests on ruminants had shown the feed was no different from conventional maize strains, it said. ``They (FoE) drew their conclusions from a selective part of the documents we supplied to the authorities,'' Aventis spokesman Gerhard Waitz told Reuters. ``As their objective is to ban GM foods they interpreted it in favour of their arguments.'' The maize was granted market authorisation by the EU in 1998 -- one of just over a dozen GM plants that have ever been allowed for use in the 15-country bloc which is sceptical of the new technology that the United States has embraced. The Aventis maize was one of the last GM products to be granted approval before the EU imposed an informal moratorium on new permits three years ago, pending new, tougher legislation on GM authorisations. Italy, Austria and Germany have since then banned a number of GM products cleared by the EU because of fears over possibly unreliable evidence. FoE said it would push all EU countries to follow suit over the Aventis maize.
