Could Contaminated Rat Chow Invalidate Data?

Could Contaminated Rat Chow Invalidate Data?

In experiments on lab rats, their food is a critical component, especially when looking into diseases that may be the result of chemicals.  Cancer, for instance, is known to originate from carcinogens as well as genetic weaknesses.  So a new study from a French team of researchers is cause for concern.

The historical data done on lab rats assumes their food is clean and relatively pure, but the researchers found levels of a variety of pesticides in standard rat chow.  They found a variety of pollutants in the 13 different types of rat food they analyzed, from five continents.

Pesticide residue from 262 types was found in the food samples.  In addition, four types of heavy metals and 22 genetically modified organisms were discovered.  While critics say the levels of these contaminants are not toxic, the study results do suggest the need for more research.

Critics, in fact, suggest that in order to truly understand how rat food might influence the develop of disease, controlled comparisons need to be made with rats who eat a truly pure diet.  Comparing an untainted diet with the typical rat chow from this study would be a better method to understand if “typical” rat food may be contributing to disease outcomes.

The study was published in PLOS ONE and the research team was led by Gilles-Eric Seralini of the University of Caen in Normandy.
