The European Food Safety Agency evaluated the paper and determined that "the author's conclusions are not supported" due to the lack of information on the input into the model, the fact that the model was not validated and because no measurements of soybeans were made to establish whether GM soy actually contained elevated levels of formaldehyde.[26] Plant scientist Kevin Folta noted that there was "no evidence ever published ... that shows a difference in formaldehyde between GM and non-GM varieties".[27] Ayyadurai later cited the study as evidence of a lack of safety standards for GM foods and bet Monsanto a $10 million building if they could prove that they were safe.
