A recent study conducted by researchers at the University of Caen in France is slated to be published in the journal, PLOS ONE. This study reveals that most rodent feed that is used for control groups in laboratory studies is actually contaminated with GMO’s, pesticides and toxic metals, even the studies on the safety of GMO’s.
The researchers analyzed 13 separate dried rodent chows produced on five continents and tested for traces of 4 heavy metals, 17 dioxins and furans, 18 PCBs, 22 GMO’s and 262 pesticides. They found that every feed had numerous toxins, toxins at high enough levels to cause diseases. If consumed over a long period of time, all of these diets could be expected to pose a high risk to health. The researchers found that 11 of the 13 diets contained GMO’s engineered to be resistant to the herbicide Roundup (glyphosate), and nine of the diets contained detectable levels of glyphosate.
Lack of Control:
These findings immediately call into the question the validity of all diet-based research conducted in rodents, especially that on potentially toxic substances, like GMO’s and PCB’s. If the control diets are actually high in toxic substances, a number of rodents in the control group are then expected to develop serious health problems. This means that the toxic effect of the substance in test would have to be exceptionally high in order to stand out from the control. If a group of animals being fed one potentially toxic substance is compared to a group being fed a cocktail of substances known to be toxic, there is essentially no control group.
With no control group, the results of these studies essentially undermine any time regulators have declared that pesticides or chemical are safe for use. Our level of “normal” at which we believe animals develop health problems is inaccurate. The high rates of “spontaneous” illness found in historic control data are not spontaneous at all.
