自20世纪80年代以来,随着转基因技术的不断进步与发展,转基因食品也越来越多的出现在人们面前,使人们在食品选择上多种多样化。转基因食品在发展过程中也展现了解决粮食短缺问题、减少农药的使用、使生产成本降低等优点。它给大众生活带来的好处是毋庸置疑的,但并没有充分的科学论据证明转基因食品是安全的,所以转基因食品在投入使用的实践中其安全性程度有待实践的检验。正是由于此项技术存在的不确定性等特征使中美大众在转基因食品安全观念上存在一定的差异。 Since the 1980s, with the continuous improvement and development of transgenic technologies, more and more genetically modified foods have appeared in front of people, making people diversify in food choices. Genetically modified foods in the development process also showed the solution to the problem of food shortage, reduce the use of pesticides, so that the cost of production and other advantages. Its benefits to the general public are beyond doubt. However, there is not sufficient scientific evidence to prove that GM foods are safe. Therefore, the safety of genetically modified foods should be tested in practice. It is precisely because of the uncertainty of the technology and other characteristics of the public in China and the United States in the concept of GM food safety there are some differences.
