Why is GMO dangerous?

In a study in the early 1990's 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 forty died within two weeks. Scientists at the FDA who reviewed the study agreed that it did not provide a “demonstration of reasonable certainty of no harm.” In fact, agency scientists warned that GM foods in general might create unpredicted allergies, toxins, antibiotic resistant diseases, and nutritional problems.

Internal FDA memos made public from a lawsuit reveal that the scientists urged their superiors to require long-term safety testing to catch these hard-to-detect side effects. But FDA political appointees, including a former attorney for Monsanto in charge of policy, ignored the scientists' warnings. The FDA does not require safety studies. Instead, if the makers of the GM foods claim that they are safe, the agency has no further questions. The GM tomato was approved in 1994.

According to a July 27, 2004 report from the US National Academy of Sciences (NAS),the current system of blanket approval of GM foods by the FDA might not detect “unintended changes in the composition of the food.” The process of gene insertion, according to the NAS, could damage the host's DNA with unpredicted consequences. The Indian Council of Medical Research (ICMR), which released its findings a few days earlier, identified a long list of potentially dangerous side effects from GM foods that are not being evaluated. The ICMR called for a complete overhaul of existing regulations.

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,[6] 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 everyday. 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.
