Regulatory control of genetically modified (GM) foods: likely developments.

摘要

The placing of genetically modified (GM) crops on the European market requires a regulatory approval supported by a thorough safety evaluation. This approach has been applied to all GM crops presently on the market. Despite this stringent process there has been an increasing public concern about the impact of GM foods on human health and the environment. In this context, regulatory control may develop in several directions. One response to the public concern is to strengthen the data requirements for the risk assessment process. Several avenues have been proposed. They include the application of technologies such as proteomics and metabolomics to assess unintended changes, and the development of predictive methods to evaluate allergenicity. Obligations for post-launch surveillance have appeared in regulations. Criteria are required to define when and why such approaches are necessary. Significant challenges including feasibility and validation of the methods, and safety relevance of the data generated will have to be addressed before any general application of these new approaches. Effective monitoring requires the ability to identify the presence of GM products and trace their origin. Traceability and labeling are therefore important developments in the GM food regulatory arena. Both require the development of reliable analytical detection tools.
