On Thanksgiving day the journal Food and Chemical Toxicology announced retraction of a study by Gilles-Eric Seralini and colleagues that has had scientists up in arms. Published only a year ago, the authors of that study claimed their data showed that rats fed genetically-modified corn suffered significantly more malignant tumors than did rats fed unmodified corn.
Among other criticisms of the paper, scientists noted
that the rat strain used is known to be particularly susceptible to cancer,
especially as the animals age — they cited another report that found a cancer
incidence of 70 to 95 percent in this strain when they were 89-105 weeks old.
Thus, the results of the Seralini research could not clearly be linked to the
rats’ diet.
In addition, the Seralini study was criticized on its
experimental design — that there were too few animals in each dietary group,
for one, and also that there were too few control dietary groups. Finally,
there was a dearth of information about the composition of the various diets
fed to the animals, nor were the levels of any pesticide residues in the GE
diets assessed…..To Read More…..
