Identification of Genetically Modified Foods - problems and unsolved questions

One of the points in the discussion of genetically modified organisms (GMO) is the consumers’ right to choose between foods from GMO (GM-foods) and traditionally produced foods. This discussion has led to the EU regulation requiring labelling of GM food products made from GM plants. However, since it is difficult to keep GM and non-GM plants materials fully separated during growing, transport etc., a threshold for labelling of GM foods was introduced.
