Genetically modified and non genetically modified food supply chains : co existence and traceability In the European Union nations and other countries including Japan Australia and Malaysia it is a legal requirement that food products containing genetically modified organism (GMO) materials are labelled as such in order that customers may make informed purchasing decisions. For manufacturers and consumers to be confident about these assertions systems must be in place along the entire food chain which support the co existence of GM and non GM materials whilst maintaining a strict segregation between the two. This book is an output of a European Union funded project entitled Co Extra: GM and non GM food and feed supply chains: their Co Existence and Traceability . The objective of this four year project is to provide practical tools and methods for implementing co existence that will: enable the co existence of genetically modified (GM) and non GM crops enable the segregation and tracing of genetically modified organism (GMO) materials and derived products along the food and feed chains anticipate the future expansion of the use of GMOs. The project is designed to foster a robustly science based debate amongst all of the stakeholders involved in the food and feed chains and the tools will be assessed not only from a technical point of view but with regard to the economic and legal aspects. It also surveys the GMO related legal regimes and practices that exist in and beyond the EU. This book examines the practical tools and methods available to implement the co existence and traceability of GM and non GM food materials along the entire food and feed chains as demanded by consumers and by legislation in force in the EU and elsewhere.
