Monsanto Corn : snopes. Claim: Studies have demonstrated that Monsanto- developed corn contains toxins that cause organ failure in rats and adverse effects in pregnant women. When field insects like European corn borer or corn rootworm larvae feed on the corn plant, the Bt protein causes them to stop feeding on the plants within a few short hours, and then they die within a few days.
It was sparked by research published in September . In females, all treated groups died 2- 3 times more than controls, and more rapidly. This difference was visible in 3 male groups fed GMOs. All results were hormone and sex dependent, and the pathological profiles were comparable.

Females developed large mammary tumors almost always more often than and before controls, the pituitary was the second most disabled organ; the sex hormonal balance was modified by GMO and Roundup treatments. In treated males, liver congestions and necrosis were 2. This pathology was confirmed by optic and transmission electron microscopy. Marked and severe kidney nephropathies were also generally 1. Males presented 4 times more large palpable tumors than controls which occurred up to 6. Biochemistry data confirmed very significant kidney chronic deficiencies; for all treatments and both sexes, 7. These results can be explained by the non linear endocrine- disrupting effects of Roundup, but also by the overexpression of the transgene in the GMO and its metabolic consequences.

Sprague- Dawley rats have a lifespan of about two years and have a high tendency to get cancer over their lifespan (one study found that over eighty percent of males and over seventy percent of females got cancer under normal conditions). So for the experiment to have adequate statistical power, all the groups — control groups and test groups — would have to include at least 6. S. OECD (Organisation for Economic Cooperation and Development) guidelines recommend 2. In addition, if the survival of the rats is less than 5.
Sprague- Dawley rats used in the study) the recommended number of rats is 6. This retraction comes after a thorough and time- consuming analysis of the published article and the data it reports, along with an investigation into the peer- review behind the article. Many of these letters called upon the editors of the journal to retract the paper. According to the journal. Due to the nature of the concerns raised about this paper, the Editor- in- Chief examined all aspects of the peer review process and requested permission from the corresponding author to review the raw data. The request to view raw data is not often made; however, it is in accordance with the journal's policy that authors of submitted manuscripts must be willing to provide the original data if so requested. However, there is a legitimate cause for concern regarding both the number of animals in each study group and the particular strain selected.
The low number of animals had been identified as a cause for concern during the initial review process, but the peer review decision ultimately weighed that the work still had merit despite this limitation. A more in- depth look at the raw data revealed that no definitive conclusions can be reached with this small sample size regarding the role of either NK6. Given the known high incidence of tumors in the Sprague. The key limitations include insensitivity of the assay method used and unsubstantiated and invalid assumptions regarding the. Cry. 1Ab protein in the diets of test subjects. Media speculation arising from this paper has also presented conclusions about the human health relevance of this paper which are not supported by either the paper itself or the broader scientific literature. There have been claims in the media that the paper is proof GM foods are not safe for human consumption.
