中文摘要：墨西哥作为玉米的起源地和品种多样性集中地，每日人均消费0.5kg玉米食品。其中，大约1000万吨玉米是由小农生产的。然而，近年来出现了很多由工业生产的玉米产品。本文从墨西哥和其他地方收集到的玉米食品中检测到转基因和草甘膦的存在，以此来描述墨西哥玉米源食品中转基因的分布、丰度和类型。研究发现，转基因序列占所有检测食品类别的82%；在墨西哥最广泛的玉米消费形式玉米饼中检测到90.4%的重组序列。我们在墨西哥和其他国家的样本中发现了统计上无法区分的频率分布。此外，在27.7%耐除草剂转基因玉米样本检测到草甘膦。
外文摘要：In Mexico, the Center of origin and diversity of maize, a daily per capita average of 0.5kg of maize-based foods are consumed. Approximately 10 million tons of maize is produced in small peasant holdings. Nevertheless, a greater proportion of industrially produced maize-derived products have started to appear in recent years. We traced the presence of transgenes and glyphosate in maize-based foods collected in Mexico and elsewhere as a means to describe the landscape of distribution, abundance, and types of transgenes in maize-derived food in Mexico. Transgenic sequences were present in overall 82% of assayed food categories; while the most widely form of maize consumption in Mexico, tortillas, had recombinant sequences in 90.4% of the samples. Furthermore, we found statistically indistinguishable frequency distributions of transgenes in samples from Mexico and other countries. Additionally, glyphosate was detected in approximately 27.7% of the samples rendered positive for transgenic events tolerant to this herbicide.
