Some disturbing new research is showing that genetically modified (GM) crops with "stacked traits" (multiple GM traits in one plant, such as both having resistance to glyphosate-herbicide and producing Bacillus thuringiensis insecticidal toxins) could be far more dangerous to human health than previously believed, as a result of synergistic toxicity.
A recent study found that when the glyphosate-containing herbicide Roundup was tested on human embryonic kidney cells, it induced cell death at concentrations as low as 50 parts per million (ppm), far lower than agricultural dilutions. The researchers also found that insecticidal toxins produced by GM plants were capable of causing cell death at 100 ppm concentrations.
Green Med Info reports:
“These disturbing findings follow on the heels of recent revelations that Roundup is several orders of magnitude more toxic than previously believed ... Roundup is toxic to human DNA even when diluted to concentrations 450-fold lower than used in agricultural applications. This effect is likely due to the presence of the surfactant polyoxyethyleneamine within the Roundup formulation which may dramatically enhance the absorption of glyphosate into exposed human cells and tissue.”
