Warning signs point to risks of GM foods (30/3/2005)

Warning signs point to risks of GM foods

IN A study in the early 1990s rats were fed genetically modified (GM) tomatoes. Well actually, the rats refused to eat them. They were force-fed. Several of the rats developed stomach lesions and seven out of 40 died within two weeks.

United States Federal Drugs Agency scientists who reviewed the study warned that GM foods in general might create unpredicted allergies, toxins, antibiotic-resistant diseases and nutritional problems.

The safety studies conducted by the biotech industry are often dismissed by critics as superficial and designed to avoid finding problems. Tragically, scientists who voice their criticism, as well as those who have discovered incriminating evidence, have been threatened, stripped of responsibilities, denied funding or tenure, or fired.

For example, a UK government-funded study demonstrated that rats fed a GM potato developed potentially pre-cancerous cell growth, damaged immune systems, partial atrophy of the liver, and inhibited development of their brains, livers and testicles. When the lead scientist went public with his concerns, he was promptly fired from his job after 35 years and silenced with threats of a lawsuit.

Americans eat genetically modified foods every day. Although the GM tomato has been taken off the market, millions of acres of soy, corn, canola, and cotton have had foreign genes inserted into their DNA.

The new genes allow the crops to survive applications of herbicide, create their own pesticide, or both. While there are only a handful of published animal safety studies, mounting evidence, which needs to be followed up, suggests that these foods are not safe.

Rats fed GM corn had problems with blood cell formation. Those fed GM soy had problems with liver cell formation, and the livers of rats fed GM canola were heavier. Pigs fed GM corn on several Midwest farms developed false pregnancies or sterility. Cows fed GM corn in Germany died mysteriously. And twice the number of chickens died when fed GM corn compared with those fed natural corn.

Soon after GM soy was introduced to the UK, soy allergies rocketed by 50 per cent. Without follow-up tests, we can't be sure if genetic engineering was the cause, but there are plenty of ways in which genetic manipulation can boost allergies.

No-one in the US or elsewhere monitors the human health impacts of GM foods. If the foods were creating health problems in the US population, it might take years or decades before we identified the cause. As a result, millions of Americans are exposed to the potential dangers, and children are most at risk. Perhaps the revelations in the reports released on opposite sides of the planet will awaken consumers as well as regulators, and GM foods on the market will be withdrawn.
