A study conducted by French Professor Gilles-Eric Seralini found that rats that were fed a diet of Monsanto’s genetically modified corn and Roundup herbicide developed severe tumors as well as kidney and liver damage.
Seralini’s controversial study titled, ‘Long Term Toxicity of a Roundup Herbicide and Roundup-tolerant genetically modified Maize,‘ concluded that GM foods could lead to a high incidence of cancer and shorten the lifespan however the editor of Food and Chemical Toxicology, A. Wallace Hayes decided to pull the study from publication stating that the evidence was inconclusive and not scientifically sound.
The editor in chief concluded that the study samples done on the rats were too small and that the rats used for the study were prone to tumor development.
“Ultimately, the results presented (while not incorrect) are inconclusive, and therefore do not reach the threshold of publication for Food and Chemical Toxicology,” said the journal.
The study in question saw 200 lab grown rats fed GMO corn and Roundup herbicide for 2 years. They found that the female rats developed mammary tumors and the male rats developed severe liver and kidney disease. All of the rats also died prematurely.
Seralini has fought back however demanding that his study is scientifically sound and that pulling the study from the journal is unethical.
