In recent year, the safety of genetically modified foods to human has been a controversial topic. There are many articles about the pros and cons of genetically modified foods and their acceptability. Genetically modified foods are foods acquire from genetically modified organisms. It involves in the removal and addition of genes by genetic engineering techniques. Most genetically modified foods are transgenic plants such as corns, soybeans, vegetables and fruits. Modified animal products have also been developing these years like pig meat. It is argued strongly that should genetically modified organisms in food be all listed out on the package for references, and the value of testing the safety of modified food.
However, genetically modified foods have couples of disadvantages on safety and ethics. Modified foods can harm human as there is no test to prove they are safe. It can cause allergens and toxin. As the genes are changed inside modified foods, people cannot identify the potential allergens to the food. A Brazil nut had been withdrawn from the shelves as it caused allergic reaction (Nordlee, 1996). The new genes in modified foods are unknowns which may produce toxic to animals, plants and humans. On the other hand, genetically modified foods have been a moral issue since they exist. Some people believe that humans do not have the right to create or destroy life, as every organism is equal in the world. Modified foods have violated this ethic due to the changes of genes. They also mix up the nature as they combine the genes of different species together.
In conclusion, genetically modified foods are benefits to humans as they are more resistance to pest and herbicides, and contain more nutrients. Besides, they can save land for other uses to prevent environmental damages. At the same time, genetically modified foods also bring humans harm. They pose menace to humans’ safety by causing allergens and toxin. Moreover, they challenge the ethical issue of some religious as they violate the belief of equality among the world. Genetically modified foods will be a hot focus continuously, and it is important for human to work hard on this topic to outweigh its benefits and reduce controversies.
