Genetically-modified foods (GM foods) have made a big splash in the news lately. European environmental organizations and public interest groups have been actively protesting against GM foods for months, and recent controversial studies about the effects of genetically-modified corn pollen on monarch butterfly caterpillars1, 2 have brought the issue of genetic engineering to the forefront of the public consciousness in the U.S. In response to the upswelling of public concern, the U.S. Food and Drug Administration (FDA) held three open meetings in Chicago, Washington, D.C., and Oakland, California to solicit public opinions and begin the process of establishing a new regulatory procedure for government approval of GM foods3. I attended the FDA meeting held in November 1999 in Washington, D.C., and here I will attempt to summarize the issues involved and explain the U.S. government's present role in regulating GM food.
What are genetically-modified foods?

The term GM foods or GMOs (genetically-modified organisms) is most commonly used to refer to crop plants created for human or animal consumption using the latest molecular biology techniques. These plants have been modified in the laboratory to enhance desired traits such as increased resistance to herbicides or improved nutritional content. The enhancement of desired traits has traditionally been undertaken through breeding, but conventional plant breeding methods can be very time consuming and are often not very accurate. Genetic engineering, on the other hand, can create plants with the exact desired trait very rapidly and with great accuracy. For example, plant geneticists can isolate a gene responsible for drought tolerance and insert that gene into a different plant. The new genetically-modified plant will gain drought tolerance as well. Not only can genes be transferred from one plant to another, but genes from non-plant organisms also can be used. The best known example of this is the use of B.t. genes in corn and other crops. B.t., or Bacillus thuringiensis, is a naturally occurring bacterium that produces crystal proteins that are lethal to insect larvae. B.t. crystal protein genes have been transferred into corn, enabling the corn to produce its own pesticides against insects such as the European corn borer.

What are some of the advantages

of GM foods?

The world population has topped 6 billion people and is predicted to double in the next 50 years. Ensuring an adequate food supply for this booming population is going to be a major challenge in the years to come. GM foods promise to meet this need in a number of ways:

Pest resistance Crop losses from insect pests can be staggering, resulting in devastating financial loss for farmers and starvation in developing countries. Farmers typically use many tons of chemical pesticides annually. Consumers do not wish to eat food that has been treated with pesticides because of potential health hazards,

GM Foods: A Big Problem With Genetically Modified Foods

2/1/13 GM Foods Argument A huge problem with genetically modified foods are allergies. Many people are highly allergic to certain types of food. Some examples are nuts, fish, or shellfish. There is a possibility that a gene that will have an allergic reaction with the consumer could be added to a plant that the person regularly consumes. For example, genes from crustaceans can be added to a plant. This adds risk with the possibilities of allergies being higher than traditionally grown crops…

The use of genetically modified foods has sparked much controversy in issues of health, political, environmental, and social aspects all over the world. I will first define a genetically modified organism (GMO) and how it’s used to create a genetically modified food (GM food). I will then give a brief history of how and why GM foods became part of U.S. food crops. I will talk about ethical, health, social, and environmental concerns of GM foods and will…

persuasive piece Should genetically modified food be allowed in Australia? According to WHO (World Health Organisation), genetically modified food refers to organisms in which genetic material has been altered in a way that does not occur naturally. Majority of the time, genetically modified (GM) food is produced through genetic engineering. To put it in simply, it is transferring pieces of DNA (Deoxyribonucleic acid) from one organism to another. Some popular examples of GM foods include canola oil…

farming increases, genetically modified foods have become more common. However, speculation is rising as these genetically modified (GM) are spreading throughout the world. While producers of these foods insist that they are safe and desirable, scientists argue that GM foods are dangerous. Genetically modified foods should be available in the global food supply only if they are safe to humans and ecosystems. As the demand for food rises, the need for genetically modified foods is increasing. Source…

GM FOOD INVESTIGATION Genetically modified foods are foods produced from genetically modified organisms or specifically genetically modified crops. The GMO’S have specific changes in their DNA by genetic engineering techniques. Many genetic modified foods are transgenic plant products such as soybean, corn, canola, and cotton seed oil.
