Most people like to know what they are eating. However, labeling for genetically modified organisms is not required in any state. This is largely because of the money expended by GM seed producers toward blocking food-labeling laws. A common claim made by this group is that GM foods have been proved safe to eat and that there is a global scientific consensus to support this statement; therefore, no labeling is needed. However, an examination of the scientific data ... show[s] that both claims are blatantly false. GM crops have fostered an epidemic of herbicide resistant weeds and insects that are no longer killed by the built-in toxins. The result is a massive increase in herbicide use -- an additional 527 million pounds over the past 16 years. The major herbicide, glyphosate, is found inside the GM plants we eat, leading to its detection in people. There is increasing evidence that GM crops and the chemicals required for their production are harmful to humans. An Associated Press story in October documented the large increase in cancer and birth defects in commercial farming areas of Argentina since the introduction of GM crops. These data confirm recent animal studies showing that GM corn and the herbicides sprayed on it caused a dramatic increase in cancer in the same strain of rats used in FDA drug safety tests. Another large study showed an increase in severe stomach inflammation in pigs caused by GM feed containing insecticidal toxins, a condition that would likely lead to cancer in humans. In reality, there is no evidence that GM food is safe for human consumption.
