Séralini, G.-E., et al. Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize. Food Chem. Toxicol. (2012)

ABSTRACT – 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.

Entre las conclusiones se afirma que “The results of the study presented here clearly demonstrate that lower levels of complete agricultural glyphosate herbicide formulations, at concentrations well below officially set safety limits, induce severe hormone-dependent mammary, hepatic and kidney disturbances.”

“Other mutagenic and metabolic effects of the edible GMO cannot be excluded. This will be the subject of future studies, including transgene and glyphosate presence in rat tissues. Reproductive and multigenerational studies will also provide novel insights into these problems. This study represents the first detailed documentation of long-term deleterious effects arising from the consumption of a GM R-tolerant maize and of R, the most used herbicide worldwide.”

Hace muchos años que Séralini viene estudiando estos temas, y ha denunciado claramente que las semilleras no dan los datos de sus estudios al conocimiento público, los consideran confidenciales. Además tratan de bloquear la investigación.  Por supuesto que gran cantidad de científicos objetan sus conclusiones, pero así se genera la ciencia. De todos modos es imprescindible recordar la necesidad de aplicar el principio de precaución.

¿Como es posible que el Ministerio de Salud argentino no haya establecido un grupo permanente de investigación sobre estos temas de contaminación por plaguicidas y salud pública? ¿Como es posible que trabajos como el que se hizo en la Sardá sobre clorados en leche materna no hayan podido completarse adecuadamente por falta de fondos para reactivos, ni hayan podido tener un seguimiento adecuado de la maduración neurológica de los niños involucrados?
