For products consistently 100% free from genetically modified material claims are currently permitted, as long as such claims can be substantiated.
Additives, flavourings and extraction solvents may have been produced from genetically modified organisms.
A tolerance of 0.9% is allowed for small quantities of GM contamination in non-GM foods but only for products from sources that are said not to be genetically modified and that have good control systems throughout the supply chain. This tolerance is only applicable to GM products that already have an EU approval. There is no threshold for any GM products that do not have an EU approval in place.
