Abstract:

The cultivated areas of genetically modified (GM) crops have been increased by an annual average of 10% speed, since their commercialized production for a large scale in 1996. In 2012, the plant area for GM crops reached 170 million hectares. GM crops have a great application prospect in solving the problems of global hunger, environment protection, improvement of food nutritional quality and convenient access to medicines. Yet GM technology exists certain risks, so it is an effective measure to strengthen the safety assessment for guaranteeing safety of GM food. Before genetically modified food enters into the market, their food safeties are assessed strictly and comprehensively, including nutrition, toxicology, allergenicity, etc. Besides, unintended effects and gut health assessment are complemented. All these measures have provided valid guarantee to avoid risks of genetically modified food and for its rapid development in the future. Any genetically modified food having passed the food safety assessment and acquired safety certificate is edible by consumers being at ease.

Key words: genetically modified crop, benefit, food safety assessment

摘要：

自1996年转基因作物大规模商业化生产以来，以年均10%左右的速度快速增长，2012年种植面积达1.7亿hm2。其在解决全球饥饿问题、保护环境、提高粮食营养品质以及方便的获取药物方面具有巨大的应用前景。但是转基因技术具有一定的风险性，加强转基因作物的安全评价是保障转基因食品安全性的有效手段。在转基因食品进入市场前，要经过严格的食用安全性评价，包括营养学、毒理学、过敏性等方面，另外有非期望效应和肠道健康评价作为补充，为转基因食品的风险规避及大力发展提供了有效的保障手段。凡是经过了安全性评价，获得了安全证书的转基因食品都有安全保障，消费者可以放心食用。
