Foodstuffs - Methods of analysis for the detection of genetically modified organisms and derived products - Polymerase chain reaction (PCR) based screening strategies
ADOPTED_FROM:CEN/TS 16707:2014
This Technical Specification describes screening strategies for the detection of genetically modified (GM) DNA in food products by means of PCR methods. The strategies have been established for food matrices, but it can also be applied to other matrices (e.g. feed, seed and samples from field grown plants). Detection of GM DNA is based on PCR methods targeting segments of transgenic DNA sequences (genetic elements, genetic constructs or insertion sites of transgenes). Various combinations of these PCR methods are involved in screening strategies. The methods are applied simultaneously or hierarchically. The general strategy is based on the matrix approach. Examples for the implementation and application of this approach are described. In order to ensure reliable analytical results, the document also provides guidelines for the validation of the performance criteria of qualitative PCR methods applied in screening approaches.
