Rotteforsøg: Roundup og GMO er kræftfremkaldende

Et video-hold har fulgt den netop fremlagte undersøgelse igennem to år.
(Et stadig helt ufærdigt indlæg) Normalt laver man kun rotteforsøg over tre måneder. Men franske forskere har nu lavet forsøg, hvor man har fulgt et kuld rotter, som man i forskellige doseringer har fodret med GMO-modificeret majs og Roundup-forurenet vand over et helt livsforløb – 2 år. Og her tegner sig et noget andet billede. Forskerne fandt, at 50% af hannerne og 70% af hunnerne døde for tidligt, sammenlignet med kun 30% og 20% i kontrolgruppen.
Og den koncentration af Roundup-forurening, som er brugt, 1 ppb, er så lav, at den er regnet som uskadelig – under grænseværdien for rent vand. Samtidig kunne man for nylig konstatere, at Roundup finder vej i stadig flere af vores drikkevandsboringer.
Undersøgelsens abstract lyder:
“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.”
