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.
