Abstract

Genetically modified (GM) maize MON 94804 was developed to achieve a reduction in plant height by introducing the suppression cassette. The molecular characterisation and bioinformatic analyses do not identify issues requiring food/feed safety assessment. None of the agronomic/phenotypic and compositional differences identified between maize MON 94804 and its conventional counterpart needs further assessment, except for ear height, plant height and levels of carbohydrates in forage, which do not raise safety or nutritional concerns. The Panel on Genetically Modified Organisms (GMO Panel) does not identify safety concerns regarding the toxicity and allergenicity of the GA20ox_SUP precursor-miRNA and derived mature miRNA as expressed in maize MON 94804 and finds no evidence that the genetic modification would change the overall allergenicity of maize MON 94804. In the context of this application, the consumption of food and feed from maize MON 94804 does not represent a nutritional concern in humans and animals. The GMO Panel concludes that maize MON 94804 is as safe as the conventional counterpart and non-GM maize varieties tested, and no post-market monitoring of food/feed is considered necessary. In the case of accidental release of viable maize MON 94804 grains into the environment, this would not raise environmental safety concerns. The post-market environmental monitoring plan and reporting intervals are in line with the intended uses of maize MON 94804. The GMO Panel concludes that maize MON 94804 is as safe as its conventional counterpart and the tested non-GM maize varieties with respect to potential effects on human and animal health and the environment.

摘要

转基因玉米MON 94804通过引入抑制盒来降低株高。分子特征分析和生物信息学分析未发现需要进行食品/饲料安全性评估的问题。除穗高、株高和饲料中碳水化合物含量外,玉米MON 94804与其传统对照品种之间所确定的农艺/表型和成分差异均无需进一步评估,而这些差异也不会引发安全性或营养方面的担忧。转基因生物小组未发现玉米MON 94804中表达的GA20ox_SUP前体-miRNA和衍生的成熟miRNA的毒性和致敏性存在安全问题,也没有证据表明基因改造会改变玉米MON 94804的整体致敏性。在本申请的背景下,食用玉米MON 94804的食品和饲料对人类和动物不构成营养方面的担忧。转基因生物小组得出结论,玉米MON 94804与传统对照品种以及所测试的非转基因玉米品种一样安全,无需对食品/饲料进行上市后监测。如果玉米MON 94804的活粒意外释放到环境中,这不会引发环境安全问题。上市后环境监测计划和报告间隔符合玉米MON 94804的预期用途。转基因生物小组得出结论,就对人类和动物健康以及环境的潜在影响而言,玉米MON 94804与其传统对照品种以及所测试的非转基因玉米品种一样安全。
