"Rats fed on a diet containing NK603 - a seed variety made tolerant to dousings of Roundup - or given water containing Roundup at levels permitted in the United States died earlier than those on a standard diet.
The animals on the GM diet suffered mammary tumours, as well as severe liver and kidney damage.
The researchers said 50 percent of males and 70 percent of females died prematurely, compared with only 30 percent and 20 percent in the control group."
These are the results of the first ever peer-reviewed, long-term animal study of GMO corn. The findings were published today:
Long Term Toxicity Of A Roundup Herbicide And A Roundup-Tolerant Genetically Modified Maize, Food and Chemical Toxicology, 19 September 2012.
"All results were hormone and sex dependent, and the pathological profiles were comparable.So, it was exposure to either the pesticide (technically herbicide) Roundup, or the corn which was engineered to be resistant to Roundup, which led to tumors in rats.
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."
Here's that endocrine-disrupting factor again. I should start a list of all the chemicals we're exposed to which are proving to be endocrine disruptors (EDs). Bisphenol A (BPA) is one. DDT, PCBs, and Phthalates are others. You have to wonder what the body burden of the entire fleet of EDs are.
The study’s authors will be hosting a press conference today to discuss the study at 11:30 am PDT.
