"The main areas for concern are twofold. The first is food safety and the second is the environmental impact," explains Tsai. Research remains to be done on food safety issues, as the implantation of foreign genes may produce proteins that human beings have never encountered, causing allergic reactions in people who consume them.
「主要的顧慮有兩方面，一是食品安全，二是對生態的衝擊，」蔡懷楨指出，食用安全的部分仍有待研究，因為外來基因的嵌入，有可能產生人類從來沒有接觸過的蛋白質，而引發食用者的過敏反應。
