In what is being described as the first ever and most
comprehensive study of the effects of genetically modified foods on
mammalian health, researchers have linked organ damage with consumption
of Monsanto’s GM maize.
All three varieties of GM corn, Mon 810, Mon 863 and NK 603, were
approved for consumption by US, European and several other national food
safety authorities. Made public by European authorities in 2005,
Monsanto’s confidential raw data of its 2002 feeding trials on rats that
these researchers analyzed is the same data, ironically, that was used
to approve them in different parts of the world.
The Committee of Research and Information on Genetic Engineering
(CRIIGEN) and Universities of Caen and Rouen studied Monsanto’s 90-day
feeding trials data of insecticide producing Mon 810, Mon 863 and
Roundup® herbicide absorbing NK 603 varieties of GM maize.
The data “clearly underlines adverse impacts on kidneys and liver,
the dietary detoxifying organs, as well as different levels of damages
to heart, adrenal glands, spleen and haematopoietic system,” reported
Gilles-Eric Séralini, a molecular biologist at the University of Caen.
Although different levels of adverse impact on vital organs were
noticed between the three GMOs, the 2009 research shows specific effects
associated with consumption of each GMO, differentiated by sex and
dose.
Their December 2009
study appears in the
International Journal of Biological Sciences (IJBS). This latest study conforms with a
2007 analysis by CRIIGEN on Mon 863, published in
Environmental Contamination and Toxicology, using the same data.
Monsanto
rejected
the 2007 conclusions, stating: “The analyses conducted by these authors
are not consistent with what has been traditionally accepted for use by
regulatory toxicologists for analysis of rat toxicology data.”
In an email to me, Séralini explained that their study goes beyond
Monsanto’s analysis by exploring the sex-differentiated health effects
on mammals, which Doull,
et al. ignored:
“Our study contradicts Monsanto conclusions because Monsanto
systematically neglects significant health effects in mammals that are
different in males and females eating GMOs, or not proportional to the
dose. This is a very serious mistake, dramatic for public health. This
is the major conclusion revealed by our work, the only careful
reanalysis of Monsanto crude statistical data.”
Other problems with Monsanto’s conclusions
When testing for drug or pesticide safety, the standard protocol is
to use three mammalian species. The subject studies only used rats, yet
won GMO approval in more than a dozen nations.
Chronic problems are rarely discovered in 90 days; most often such
tests run for up to two years. Tests “lasting longer than three months
give more chances to reveal metabolic, nervous, immune, hormonal or
cancer diseases,” wrote Seralini
et al. in their Doull rebuttal.
Further, Monsanto’s analysis compared unrelated feeding groups,
muddying the results. The June 2009 rebuttal explains, “In order to
isolate the effect of the GM transformation process from other
variables, it is only valid to compare the GMO … with its
isogenic non-GM equivalent.”
The researchers conclude that the raw data from all three GMO studies
reveal novel pesticide residues will be present in food and feed and
may pose grave health risks to those consuming them.
They have called for “an immediate ban on the import and cultivation
of these GMOs and strongly recommend additional long-term (up to two
years) and multi-generational animal feeding studies on at least three
species to provide true scientifically valid data on the acute and
chronic toxic effects of GM crops, feed and foods.”
Human health, of course, is of primary import to us, but ecological
effects are also in play. Ninety-nine percent of GMO crops either
tolerate or produce insecticide. This may be the reason we see
bee colony collapse disorder and massive
butterfly deaths.
If GMOs are wiping out Earth’s pollinators, they are far more
disastrous than the threat they pose to humans and other mammals.
