Long term toxicity
Long term toxicity of a Roundup herbicide and a Roundup-tolerant genetically modified maize [click on link to access article]
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 for 2 years in rats.
• 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.
