Monsanto “Round up” herbicide on GMO corn: Rat study: 2-3X more deaths in females


The health effects of a Roundup-tolerant genetically modified maize (from 11% in the diet), cultivated with or without Roundup, and Roundup alone (from 0.1 ppb in water), were studied 2 years in rats. 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. This pathology was confirmed by optic and transmission electron microscopy. 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, but also by the overexpression of the transgene in the GMO and its metabolic consequences.


► A Roundup-tolerant maize and Roundup provoked chronic hormone and sex dependent pathologies. ► Female mortality was 2–3 times increased mostly due to large mammary tumors and disabled pituitary. ► Males had liver congestions, necrosis, severe kidney nephropathies and large palpable tumors. ► This may be due to an endocrine disruption linked to Roundup and a new metabolism due to the transgene. ► GMOs and formulated pesticides must be evaluated by long term studies to measure toxic effects.

    Just one question: When are we going to start acting like war is being conducted against us. Not a fair war, true, but a war nonetheless. And I would love to start hearing about alternative responses to war against us and how do we fight back? Do we do like SunTsu says, take their tools and use them against them?

    Do we find a sneaky way to poison their food and water? Do we poison their drugs? Do we do bogus false flags on them? The system is either corrupt or gone, and that means we are on our own, so lets begin talking about options. Its way past time to do that.

    One more hurricane or earthquake in California and the west coast and that will be the final straw. They have already collected our citizens from a man made hurricane they made with haarp and then, using military on American soil in total violation of our constitution, they rounded up 375,000 of our fellow American citizens. SO ITS TIME TO AT LEAST START THINKING ABOUT IT SERIOUSLY.

    Consider their use of deception as well. Lets use our creativity that they lack.

    You may haven’t meant to do thus, however I think you’ve got manegad to express the state of mind that a heap of people are in. The sense of wanting to help, but not knowing how or where, is one thing a heap folks are going through.
