The results of a survey study on food samples produced from genetically modified soybean and maize collected from the Egyptian market are presented. Forty samples of soybean and 40 samples of maize products have been gathered randomly from markets in Cairo and Giza. The genetic modification was detected by polymerase chain reaction (PCR) using official detection methods according to section 35 of the German Foodstuffs Act. Samples were investigated for the presence of material derived from the following genetically modified organisms (GMOs) all of which are approved for food use in Europe: Roundup Ready soybean (RRS) and maize lines Bt176, Bt11, T25 and MON810. In addition, samples were examined in qualitative and quantitative analysis for the presence of material derived from the transgenic maize line StarLink (Aventis) which was approved for animal feed use exclusively in the US. Twenty % of 40 investigated soy samples contained Roundup Ready soybean; 15% of 40 maize samples tested positive for Bt176 and 12.5% positive for Bt11 maize. Furthermore, the presence of StarLink maize could clearly be demonstrated in four samples mixed with Bt176 and Bt11. The percentage of StarLink was less than 1% in quantitative analysis. The maize lines T25 and MON810 were not detected.
本文展示了一项针对从埃及市场采集的转基因大豆和玉米食品样本的调查研究结果。从开罗和吉萨的市场随机收集了40份大豆样本和40份玉米产品样本。根据德国食品法第35条的官方检测方法，采用聚合酶链反应（PCR）检测基因改造情况。对样本进行调查，以确定是否存在源自以下转基因生物（GMO）的物质，所有这些转基因生物在欧洲均被批准用于食品：抗草甘膦大豆（RRS）以及玉米品系Bt176、Bt11、T25和MON810。此外，还对样本进行了定性和定量分析，以检测源自转基因玉米品系StarLink（安万特）的物质，该品系仅在美国被批准用于动物饲料。在所调查的40份大豆样本中，20%含有抗草甘膦大豆；40份玉米样本中，15%的Bt176检测呈阳性，12.5%的Bt11玉米检测呈阳性。此外，在四份与Bt176和Bt11混合的样本中，能够明确检测到StarLink玉米的存在。在定量分析中，StarLink的比例小于1%。未检测到玉米品系T25和MON810。
