中文摘要：本文对土耳其含有玉米的食品和饲料产品中转基因材料的含量进行了评估。作者用多重实时聚合酶链反应检测83种食品和饲料产品（没有转基因材料标签）的35S、NOS、bar和FMV指标。18.2%的饲料和6%的食品样品对一个或多个指标呈阳性，并用品系特异性PCR来识别其包含的转基因物质。大多数样品的指标呈阴性，这表明他们可能含有外源转基因污染物。研究表明，目前的立法限制了转基因玉米渗透到土耳其食品工业，但并没有消除它；且不同转基因事件的扩散，使得监测越来越复杂。另外，在某些情况下，立法标签的要求并没有被遵守。
外文摘要："BACKGROUND: EU legislation strictly controls use of genetically modified (GM) crops in food and feed products, and requires them to be labelled if the total GM content is greater than 9 g kg(-1) (for approved GM crops). We screened maize-containing food and feed products from Turkey to assess the prevalence of GM material.
RESULTS: With this aim, 83 food and feed products - none labelled as containing GM material -were screened using multiplex real-time polymerase chain reaction (PCR) for four common GM elements (35S/NOS/bar/FMV). Of these, 18.2% of feeds and 6% of food samples tested positive for one or more of these elements, and were subjected to event-specific PCR to identify which GM organisms they contained. Most samples were negative for the approved GM events tested, suggesting that they may contain adventitious GM contaminants. One sample was shown to contain an unapproved GM event (MON810, along with GA21) at a concentration well above the statutory labelling requirement.
CONCLUSION: Current legislation has restricted the penetration of GM maize into the Turkish food industry but not eliminated it, and the proliferation of different GM events is making monitoring increasingly complex. Our results indicate that labelling requirements are not being followed in some cases. (C) 2015 Society of Chemical Industry"
