On issues such as labelling and traceability of GM foods as a way to address consumer preferences, there is no worldwide consensus to date. Environmental concerns include the risk of altered genes entering wild species. In addition, research has shown that GMO foods are no likelier to trigger allergies than their non-GMO counterparts (16). Why has there been concern about GM foods among some politicians, public interest groups and consumers? While hundreds of published reports have explored the benefits and risks of GMO foods, many people strongly believe GMOs are unsafe for human consumption. The Codex Alimentarius Commission (Codex) is the joint FAO/WHO intergovernmental body responsible for developing the standards, codes of practice, guidelines and recommendations that constitute the Codex Alimentarius, meaning the international food code. Lastly, we have the word Organism. Scribd is the world's largest social reading and publishing site. ESL Printables, That said, more long-term human research is necessary. Resistance against insects is achieved by incorporating into the food plant the gene for toxin production from the bacterium Bacillus thuringiensis (Bt). In contrast, most national authorities consider that specific assessments are necessary for GM foods.

The WHO Department of Food Safety and Zoonoses aims at assisting national authorities in the identification of foods that should be subject to risk assessment and to recommend appropriate approaches to safety assessment. This means that individual GM foods and their safety should be assessed on a case-by-case basis and that it is not possible to make general statements on the safety of all GM foods. Continuous application of safety assessments based on the Codex Alimentarius principles and, where appropriate, adequate post market monitoring, should form the basis for ensuring the safety of GM foods. based on the need to examine the potential negative effects on human health of the consumption of food produced through genetic modification in order to protect public health. 1973: Biochemists Herbert Boyer and Stanley Cohen develop genetic engineering by inserting DNA from one bacteria into another. Herbicide tolerance is achieved through the introduction of a gene from a bacterium conveying resistance to some herbicides. GM fruits and vegetables can stay good longer. Tackle literacy and science by having your students read and answer questions from a scientific article. Potential advantages of GMO crops include: Growing plants that are more resistant to diseases spread by insects or viruses will likely result in higher yields for farmers and a more attractive product. Although the probability of transfer is low, the use of gene transfer technology that does not involve antibiotic resistance genes is encouraged. As genetically modified produce makes its way to market this year, experts debate whether these foods are safer to consume than other products. A person grows plants from the new seeds. As a matter of principle, the transfer of genes from commonly allergenic organisms to non-allergic organisms is discouraged unless it can be demonstrated that the protein product of the transferred gene is not allergenic. While cancer rates have changed over time in the U.S., there is no evidence that these changes coincide with the introduction of GMO foods. Its also worth noting that any food labeled 100% organic does not contain any GMO ingredients, because U.S. law prohibits this. GMO crops are relatively new, and researchers are still investigating their long-term safety and health effects, but no evidence has yet emerged that currently available GMO foods are harmful to human health. As such, the GMO crops dont need to be exposed to harmful pesticides as often (3).
