A decision on legislation to ensure the traceability of genetically modified products in the food chain has again been put off by the European Commission. The Brussels executive was due to agree and table its proposed regulation this week, but it is thought unlikely this will be done before August. Traceability and labelling provisions for all GM products is regarded by the commission as the last stage of its set of rules on new or "novel" GM feed and seed within the framework of biotech legislation. But it is proving almost impossible to find testing methods which will give full traceability because many substances produced through GM technology do not show any trace of GM protein in the final processed foods. The commission aims to provide legislation strong enough to persuade member states to drop their effective moratorium on all new GM products, but its advisers cannot agree on relevant trace tests. {{NEWS }}
