Detection of genetically modified (GM) crops for control of animal feed integrity

This chapter discusses several key points on the detection of genetically modified (GM) crops. Since the introduction of GM crops, the market volume has increased considerably and in parallel so have the regulations concerning the use of these crops as food or feed. Regulating novel crops requires monitoring of exports and imports of GM crops. The reliability of detection assays is heavily influenced by sampling errors, extent of feed/food processing, matrix effects and associated DNA/protein extraction protocols. In the future, novel and stacked GM traits are expected to replace or complement those that have already been introduced into agricultural crops. Consequently, methodologies and legislative approaches will have to continue to evolve to ensure the continued integrity and safety of the feed and food system.
