欧盟评估转基因甜菜KWS20-1用于食品和饲料中的安全性

 　　  2025年5月12日，欧盟食品安全局（EFSA）发布消息，应欧盟委员会要求，欧盟食品安全局转基因生物（GMO）专家组就转基因甜菜KWS20-1用于食品和饲料中的安全性发表科学意见。 
　　经过评估，转基因小组得出结论，就对人类和动物健康及环境的潜在影响而言，转基因甜菜KWS20-1与其传统对应品种和经过测试的非转基因甜菜品种一样安全。部分原文报道如下：
 
　　Genetically modified sugar beet KWS20-1 was developed to confer tolerance to glyphosate-, dicamba- and glufosinate-ammonium-based herbicides. These properties were achieved by introducing the cp4 epsps, dmo and pat expression cassettes. The molecular characterisation data and bioinformatic analyses do not identify issues requiring further safety assessment. None of the identified differences in the agronomic/phenotypic and compositional characteristics tested between sugar beet KWS20-1 and its conventional counterpart need further assessment, except for pectin in roots, which underwent additional evaluation and was found not to raise any safety or nutritional concerns. The GMO Panel does not identify safety concerns regarding the potential toxicity and allergenicity of the CP4 EPSPS, DMO and PAT proteins as expressed in sugar beet KWS20-1, and finds no evidence that the genetic modification would change the overall safety of sugar beet KWS20-1 as food and feed. In the context of this application, the consumption of food and feed from sugar beet KWS20-1 does not represent a nutritional concern in humans and animals. The GMO Panel concludes that sugar beet KWS20-1 is as safe as the conventional counterpart and non-GM sugar beet reference varieties tested, and no post-market monitoring of food/feed is considered necessary. The scope of the application does not include cultivation and import of viable materials in the EU and the products would be expected to only contain residual amounts of DNA and protein. The environmental risk assessment was limited to the possible plant-to-bacteria horizontal gene transfer and the evaluation of potential interactions of KWS20-1 sugar beet products with biogeochemical cycles, and neither of them indicates a safety concern. The GMO Panel concludes that the sugar beet KWS20-1 is as safe as its conventional counterpart and the tested non-GM reference sugar beet varieties with respect to potential effects on human and animal health and the environment.
