Commentary: Worst anti-biotech study ever
“Basically, the paper is garbage.”
Indeed, the researchers used the Sprague-Dawley line that is bred to be highly susceptible to the development of tumors. That particular strain has a more than 80% chance of growing tumors within two years under non-experimental conditions.
“You can’t draw any conclusions from that small of a population,” Van Eenennaam said. “To suggest that the tumors were the result of Roundup, the GMOs or an interaction between the two is ludicrous. It’s Fantasyland stuff. How was this study was even published in the first place?”
The Frankenfoods card
That’s a good question, and one without a good answer. There simply aren’t any data to suggest that the genetic engineering of crops poses any significant threat to human health. Even the staunchest critics of Frankenfoods can only invoke the precautionary principle to support their fevered opposition—that, and vague warnings that “we don’t know about the long-term effects” of consuming genetically engineered foods.
This study won’t add any heft to the activists’ portfolio, that’s for sure.
“I think someone who had taken a basic biology or statistics class could have rejected this paper,” said Dr. Bruce Chassy, Professor Emeritus in Food Science and Human Nutrition at the University of Illinois.
Chassy noted there have been more than 200 studies comparing GM foodswith non-GM foods in at least 15 animal species, and almost every one shows no difference in animal health. He suggested that the researchers have a political agenda and noted that the primary author of the study is the leader of an anti-GM lobbying group called CRIIGEN (Committee for Research and Independent Information on Genetic Engineering).
If all that isn’t damning enough, Dr. Van Eenennaam raised one final point that identifies perhaps the most egregious departure from scientific protocol.
“What really concerned me were the photos of the rats with abnormally large tumors,” she said. “I realize that they were trying to prove a point, but you don’t make animals suffer to do it. At our lab, once a tumor exceeds 40 millimeters, the animal is sacrificed. We take animal welfare very seriously, and for these researchers to allow the [treated] rats to grow tumors as large as the ones they photographed is absolutely appalling.”
As are their methods, their conclusions and their betrayal of the most critical aspect of scientific inquiry: Its credibility.
