Biological Safety (GMOs)
In recent years, molecular biological research introduced new information into the genome of plants. The novel food regulation demands that food containing raw material from such plants must be declared. Therefore the food industry is obliged to have detection systems to identify these genetic modifications. PCR can give this information even when DNA content is very low. After isolation of DNA from various food matrices the modified part of the genome is amplified by PCR and then detected by a specific gene probe.
According to the European Legislation, foods that contain, consist of or are produced by non-approved genetic modifications, which have not been assessed by the European Food Safety Authority, should be classified as unsafe for human health. Additionally, if a food contains an approved genetically modified constituent at a concentration more than 0.9%, this should be clearly stated on its label (Regulation EC 1829/2003).
