Objective To research and debate the arguments for and against the use of genetically modified foods. The issues of the safety of and need for genetically modified foods are being hotly debated in the United States, Europe, and other countries. To help students understand this complex issue, tell them they have been appointed to brief a special Food and Drug Administration review board about the pros and cons of genetically modified foods.
Genetically modified foods: safety, risks and public concerns—a review
Genetically modified organism GMO , organism whose genome has been engineered in the laboratory in order to favour the expression of desired physiological traits or the generation of desired biological products. In conventional livestock production, crop farming, and even pet breeding, it has long been the practice to breed select individuals of a species in order to produce offspring that have desirable traits. In genetic modification, however, recombinant genetic technologies are employed to produce organisms whose genomes have been precisely altered at the molecular level, usually by the inclusion of genes from unrelated species of organisms that code for traits that would not be obtained easily through conventional selective breeding. A genetically modified organism GMO is an organism whose DNA has been modified in the laboratory in order to favour the expression of desired physiological traits or the production of desired biological products. Genetically modified organisms GMOs provide certain advantages to producers and consumers. Modified plants, for example, can at least initially help protect crops by providing resistance to a specific disease or insect, ensuring greater food production.

Commercial potential of biotechnology is immense since the scope of its activity covers the entire spectrum of human life. The most potent biotechnological approach is the transfer of specifically constructed gene assemblies through various techniques. However, this deliberate modification and the resulting entities thereof have become the bone of contention all over the world. Benefits aside, genetically modified organisms GMOs have always been considered a threat to environment and human health. In view of this, it has been considered necessary by biosafety regulations of individual countries to test the feasibility of GMOs in contained and controlled environments for any potential risks they may pose. This paper describes the various aspects of risk, its assessment, and management which are imperative in decision making regarding the safe use of GMOs.
The debate over the environmental impact of genetically modified GM crops is growing increasingly complex, intense, and extremely emotional. It is further complicated as new research is published. Are GM crops safe for the environment? Assessing the environmental impact of GM crops is often difficult as many factors are considered. Some scientists focus on the potential risks of GM crops, while others emphasize their potential benefits. Just what are the issues and how can we address them?

Meanwhile, cultivation of GMOs remains forbidden in over thirty nations. In , a majority of European Union countries decided to block the cultivation of eight new types of GMO pending new data and approval from regulatory bodies. Nonetheless, the European Union remains the greatest user of GMOs: 30 million tonnes of genetically modified soya beans and corn are required for animal feed every year.

In this chapter, the committee examines the evidence that substantiates or negates specific hypotheses and claims about the health risks and benefits associated with foods derived from genetically engineered GE crops. There are many reviews and official statements about the safety of foods from GE crops for example, see Box , but to conduct a fresh examination of the evidence, the committee read through a large number of articles with original data so that the rigor of the evidence could be assessed. Some of the evidence available to the committee came from documents that were part of the U.
Genetic modification is a special set of gene technology that alters the genetic machinery of such living organisms as animals, plants or microorganisms. The principal transgenic crops grown commercially in field are herbicide and insecticide resistant soybeans, corn, cotton and canola. There are bananas that produce human vaccines against infectious diseases such as hepatitis B, fish that mature more quickly, fruit and nut trees that yield years earlier and plants that produce new plastics with unique properties. Technologies for genetically modifying foods offer dramatic promise for meeting some areas of greatest challenge for the 21st century. Like all new technologies, they also pose some risks, both known and unknown. Controversies and public concern surrounding GM foods and crops commonly focus on human and environmental safety, labelling and consumer choice, intellectual property rights, ethics, food security, poverty reduction and environmental conservation. This review will also address some major concerns about the safety, environmental and ecological risks and health hazards involved with GM foods and recombinant technology.
