Identity, traceability, acceptability and substantial equivalence of food

The numerous food crises that Europe has experienced during the past five years have raised new consumer demands concerning the characterization, traceability, and safety of foods which are proposed on the market. The consumer has, at the same time, vigorously placed into question the modes of agricultural production in industrialized countries, as well as the structures and means of evaluating the food risks and the conditions of the consumer's participation in the public debate in these domains. For certain groups of consumers, one also attends a contestation of the expertise and the application to the food domain of the considerable progress that has taken place in the field of biotechnology. So it is that the development of genetically modified organisms (mainly plants, the raw material of food products) has experienced a slowing down in the European Union. The answers afforded to these new exigencies of consumers in matter of identity, traceability, and acceptability of the foods are dealt with in this paper, as well as the elements which may concur with the evaluation of their safety. The positive role that biotechnology can afford to the different domains is emphasized. A source of uneasiness, biotechnology is also a powerful tool for ameliorating the evaluation of the sanitary risks and for answering the hopes of the citizen in the food domain.
