Lab rats and the corruption of how we count

Lab rats and the corruption of how we count

There’s an old joke about lab rats in which the teller says he or she secretly suspects that all lab rats are prone to cancer and so all research about the risk of cancer in humans based on tests in rats is likely useless.

The Committee for Independent Research and Information on Genetic Engineering, a European-based research group, thought it would look into such a possibility.

Last week the group released its findings and that joke became a reality. The diet fed to most lab rats is so laced with pesticides, heavy metals, genetically engineered feed and other man-made contaminants that lab rats worldwide are indeed at much higher risk of developing cancer and other diseases and disabilities just from the food they are reared on.

This doesn’t necessarily mean that certain substances thought likely to cause cancer in rats and possibly humans now somehow don’t. Rather, the study calls into question practically all safety tests which rely on these rodents. And, in fact, it suggests that the dangers of many substances and genetically engineered plants may have been underplayed.

The researchers point out that some studies purporting to demonstrate the safety of genetically engineered foods fed significant amounts of such GE foods to control groups of rats. These rats should not have gotten any GE food in order that their health profile could be compared accurately to those intentionally fed GE food.

And, even if the rats in the control groups don’t ingest the chemical or plant being tested–as is the case in a proper study–they still get sick at abnormally high rates due to their diet. That can make substances being tested appear safer than they truly are because it is more difficult to sort out which effects in the test group are due to the substance or plant being tested.
