First of all, it is necessary to display a clear definition and societal issues towards genetically modified foods. Genetically modified foods are species whose genes have been changed to perform a desired function (Le, Fernandez & Gabriel, 2004). However, the public concerns about genetically modified foods are not optimistic. In Western Europe, 70 per cent of consumers are against genetically modified foods (Ritsema, 2006). The huge number of rejection lead to the decline of market and industry. Thus, why do many people against genetically modified foods.
While genetically modified foods bring benefits, there are still several safety issues towards genetically modified foods. As for human health, the concerns for safety, allergenicity, toxicity, carcinogenicity, and altered nutritional quality of food are controversial. Due to the fact that GM contains the transfer of genes that may code for proteins not normally present, which means there exist unknown character will be more or less allergenic than their conventional
