例如，如果基因工程单单从一种安全粮食作物的一种普通食物成分的基因转移到另一种作物，这并不使消费者受到事物供给中新成分的影响。

For example, if genetic engineering simply moves a gene for a common food ingredient from one safe food crop to another, this does not expose consumers to new components in their food supply.

表面看来，这似乎不太可能，因为基因工程赋予它们的特征是为了使它们成为更好的食物，而不是竞争力强的高效繁殖机器。

On the face of it, this seems unlikely, because the characteristics that have been engineered into them are ones designed to make them into better food, rather than lean, mean breeding machines.

在过去的十年中，食物行业已经把这个小儿科提升到了一个全新的水平，形成了农作物基因工程。

Within the past decade, the food industry has taken such tweaking to a whole new level with the genetic engineering of crops.
