A 2 year feeding study was completed on rats that were given either Roundup-tolerant genetically modified maize, cultivated with or without Roundup, and Roundup alone, at levels permitted in drinking water and GM crops in the US (only 90 day feeding trials were conducted by the biotech industry). The results were an unprecedented confirmation of the cancer-causing effects of GM food and agrichemicals, reported as follows:
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 2.5–5.5 times higher. Marked and severe kidney nephropathies were also generally 1.3–2.3 greater. Males presented 4 times more large palpable tumors than controls which occurred up to 600 days earlier. Biochemistry data confirmed very significant kidney chronic deficiencies; for all treatments and both sexes, 76% of the altered parameters were kidney related. These results can be explained by the non linear endocrine-disrupting effects of Roundup and also by the over expression of the transgene in the GMO and its metabolic consequences.
The results of this new study are concerning. Not only has the consumption of a genetically modified corn now been shown to cause tumor growth and accelerated mortality, but so, too, has the primary herbicide these plants have been engineered to withstand exposure to: Roundup.
The precautionary principle requires that if there is indication in a non-human study that a substance is toxic to those who are forced to ingest it, inhale it, or otherwise be exposed to it, the burden of proving it safe must be on those manufacturing, marketing it and/or releas ing it into the environment (which we know isn’t going to happen). America — albeit, unbeknownst to most of the population – has been engaged in a mass chemical and feeding experiment, without the protection of informed consent, or even the right to know what it is eating through truthful labeling of GMOs.
