GM Foods

 

Genetically modified (GM) Foods

GM foods are foods made from genetically modified organisms (GMO) that have had their DNA altered through genetic engineering. The process of producing a GMO used for GM Foods may involve taking DNA from one organism, modifying it in a laboratory, and then inserting it into the target organism’s genome to produce new and useful genotypes or phenotypes. Such GMOs are generally referred to as transgenics. Other methods of producing a GMO include increasing or decreasing the number of copies of a gene already present in the target organism, silencing or removing a particular gene or modifying the position of a gene within the genome.

 

No field of science has changed more, or changed the world more, in the last 50 years than genetics – the study of how our physical and behavioral traits are inherited. The field’s crowning achievement may have been the spelling out of our genetic secrets by the human genome project, but scientific and technological advances in genetics have forever transformed agriculture, biology, medicine, zoology, and even fields such as anthropology and forensic science.

 

Modern genetics, however, is rarely taught in Arab colleges and universities. To compound consumer problems, none of the Food Labs or institutions that are responsible for consumer products runs programs to verify whether food stuff on local shelves have any GM products or even raw material. Unlike EC (where GM foods are still illegal), Arab countries have no regulations regarding GM foods.

 

GM Organisms:

By far the most common genetically modified (GM) organisms are crop plants. But the technology has now been applied to almost all forms of life, from pets that glow under UV light to bacteria which form HIV-blocking "living condoms" and from pigs bearing spinach genes to goats that produce spider silk.

 

GM tomatoes, as puree, first appeared on British supermarket shelves in 1996 (a different fresh GM tomato first appeared in the US in 1994), but the consumer furor that surrounded GM technology did not erupt until February 1999. This was because a controversial study suggested that a few strains of GM potatoes might be toxic to laboratory rats. Those experiments, subsequently criticized by other experts, were carried out in Scotland by biochemist Arpad Pustzai.
