Awareness is rising that we are subject to
an exponential exposure to herbicide, glyphosate. Besides widespread use in landscaping and
conventional agriculture, many GM crops are designed to accumulate this
herbicide and they have become ubiquitous in our food chain, adding hugely to
the burden.
Experiments on rats suggest 35-40% of
ingested glyphosate enters the body.
Because glyphosate is highly soluble in water, it would be expected to
disperse throughout body fluids.
Indeed, studies have confirmed that
glyphosate is circulating in human blood and is excreted in urine [1,2]. Testing of cows fed GM glyphosate-tolerant GM
feed indicates an even dispersion of
glyphosate in the intestine, liver, muscles, spleen, kidneys and urine, and the
levels of the herbicide there are correlated with dietary presence.
A senior Monsanto scientist has asserted
that “If ingested, glyphosate is excreted rapidly, does not accumulate in body
fat or tissues, and does not undergo metabolism in humans. Rather, it is excreted unchanged in urine”.
Regulators seem happy to accept this view.
However, is glyphosate really doing
nothing as it passes through our bodies, as Monsanto says?
