GENETICALLY MODIFIED FOODS

Genetically modified foods are those foods that have been altered genetically in order to increases it's size. Scientist has often warned that introducing genetically modified materials into organisms could change the natural properties of most plants i.e. plants may never evolve naturally of which from my perspective will be extremely dangerous.
This very technology known to be recombinant DNA technology is capable of changing the genetic makeup of organisms. Scientist says that it helps them in creating traits that they wish of to surprises natural traits they don't want.

THE EFFECTS OF THE GENETICALLY MODIFIED FOODS (GMO)
There are several reasons why the genetically modified foods (GMO), may affect you some of which:
1. It is usually not clear which of the foods may contain genetically modified foods (GMO)
2. One may not be too certain about the long term effects of these genetically modified foods (GMO)
3. Agro- chemical companies and the governments may charge farmers fees to grow their genetically modified foods crops, there by affecting the economy negatively
What are the potential dangers of genetically modified foods?
Genetically engineered products clearly have the potential to be toxic and a threat to human health. In 1989, a genetically engineered brand of L-tryptophan, a common dietary supplement, killed 37 Americans and permanently disabled or afflicted more than 5,000 others with a painful and potentially fatal blood disorder, eosinophilia myalgia syndrome (EMS), before it was recalled by the U.S. Food and Drug Administration.
The manufacturer, Showa Denko, Japan's 3rd largest chemical company, had for the first time in 1989 used genetically engineered bacteria to produce the over-the-counter supplement. It is believed that the bacteria somehow became contaminated during the recombinant DNA process. Showa Denko has already paid out over $2 billion in damages to EMS victims.
Dr. Arpad Pusztai on genetically modified foods
In 1999, front-page headline stories in the British press revealed Rowett Institute scientist Dr. Arpad Pusztai's explosive research findings that genetically engineered potatoes, spliced with DNA from the snowdrop plant and a commonly used viral promoter, the Cauliflower Mosaic Virus (CaMv), are poisonous to mammals. Genetically engineered-snowdrop potatoes, found to be significantly different in chemical composition from regular potatoes, damaged the vital organs and immune systems of lab rats which were fed the genetically engineered potatoes.
Most alarming of all, damage to the rats' stomach linings - apparently a severe viral infection - most likely was caused by the CaMv viral promoter, a promoter spliced into nearly all genetically engineered foods and crops.
In August 1998, Dr. Pusztai appeared on the British television program 'The World in Action' to report the findings of his study. In an attempt to appease the resulting public furor, Rowett Institute director Philip James (who had approved Dr. Pusztai's television appearance) said the research didn't exist. He fired Dr. Pusztai, broke up his research team, seized the data, and halted 6 other similar projects.
It later became known that Monsanto, a leading U.S. biotech firm, had given the Rowett Institute a $224,000 grant prior to Dr. Pusztai's interview and subsequent firing.
Evidence emerged which supports the legitimacy of Dr. Pusztai's research. The research that James claimed did not exist showed up during an internal audit. Later, 'Lancet', the prestigious British medical journal, published a peer-reviewed paper which Dr. Pusztai had co-authored supporting the research.
Prince Charles began to question the safety of genetically engineered foods on his website and became allies with Dr. Pusztai. Charles wrote an article in the 'Daily Mail' expressing concerns over the lack of safety research on genetically engineered foods.
The U.S. media has not covered the disturbing public health questions raised by Dr. Arpad Pusztai's research into genetically engineered potatoes. Genetic engineering continues to receive a clean bill of health by United States' regulatory agencies despite the fact that no independent, government-supported research has been or is being conducted into the effects of genetically engineered foods on mammals.
This is in large part due to the fact that the biotech industry has a sophisticated public relations apparatus in place which has so far successfully been able to spin the industry's line that genetically altered food is absolutely safe. To better understand how public relations firms shape the public's awareness and beliefs
Perhaps the most important event in the last few years was the contamination of the food supply with the unapproved genetically engineered Star Link corn. The corn had been approved by the Environmental Protection Agency for consumption by animals but not humans, because of concerns that it may cause allergic reactions
The Star Link discovery by a coalition of advocacy groups has resulted in approximately 300 food products being recalled, mass litigation within the agriculture community, and drops in exports to key markets. Star Link has also raised questions about the United States' regulatory system, and at the end of 2000, several bills in Congress were proposing major changes in the way U.S. agencies regulate these crops.
