The startling claims regarding risk of long term exposure to GMO
crops and round Up generally has certainly stirred up a reaction that
will now generate plenty of science. My own thoughts on all this is
that the proposed long term cause and effect is somewhat surprising
and unexpected. That it had not been eliminated in the literature by
the manufacturers says much to the validity of the claim as well.
However, my expectation is that this will sort itself out and the
danger will turn out to be below the error threshold.
In the really long term, agriculture will go full organic anyway and
all this will go away.
Panels reject study
on GM corn but urge wider probes
by Staff Writers
Paris (AFP) Oct 22, 2012
Two expert panels on
Monday rejected a contested French study linking genetically-modified
corn to tumours in rats but said it raised issues which deserved
wider investigation.
Asked by the
government to deliver a fast-track verdict, two groups of specialists
reported they found no evidence to back what the study said.
The
Higher Biotechnologies Council (HCB) and the National Agency for Food
Safety (ANSES) declared they saw nothing to challenge existing safety
assessments for Monsanto's NK603 corn or its Roundup weed killer,
which was part of the experiment.
"The study
provides no scientific information regarding the detection of any
health risk linked to NK603 corn, whether it was treated with Roundup
or not," said the 66-member HCB, set up in 2009 to provide an
independent view.
"The data are
insufficient to establish scientifically a causal link... or to
support the conclusions or pathways suggested by the authors,"
ANSES said separately.
But both called for a
broader investigation to guide a public left rattled or confused by
the debate.
The HCB said the
inquiry should look into whether NK603 had long-term impacts on
health, while ANSES urged a probe into any consequences of combined
exposure to NK603 and Roundup.
In
response, the French government said it would ask the European Union
to "overhaul" its procedures for vetting GM crops and
pesticides in the light of ANSES' proposal.
"In this context,
the government reaffirms its determination to maintain France's
moratorium on GM crops" authorised for cultivation in the
EU, it said.
The storm was
unleashed in September by researchers led by Gilles-Eric Seralini at
the University of Caen in Normandy, who said rats fed with the
genetically-modified corn and/or doses of Roundup developed tumours.
The paper unleashed a
storm in environmentally-sensitive Europe, where GM crops face many
restrictions.
NK603 has been
engineered to make it resistant to Roundup, so that farmers can douse
fields with the Monsanto weed killer in a single go, offering
savings.
Roundup
was launched in 1970 by Monsanto and it became the most used weed
killer in the United States. Its producers say its toxicity is
limited in comparison with other herbicides.
Seralini said his
experiment was the first to test GM corn on rodents' normal life span
of two years, as opposed to the standard 90 days. He said NK603 and
Roundup both caused tumours, whether they were consumed together or
on their own.
But critics faulted
the experimental methods and data and accused him of manipulating the
media to gain scary headlines.
In an exceptional
move, six French science academies on Friday branded the work as
flawed and said it had "spread fear among the public".
Among reactions,
Seralini said he welcomed a wider investigation but said that in the
meantime, NK603 should be banned.
"A two-year study
takes four years to set up and analyse, and during these four years,
who else is going to fall sick or die because of these poorly-tested
products?" he told AFP in a phone interview.
Monsanto said at its
French headquarters in Lyon that "it took note" of the
HCB's findings and said the recommended probe "does not change
risk assessments" for NK603.
Environmental group
Greenpeace said Seralini had exposed a gap in testing transgenic
products for their long-term impact on health and the environment.
"No suitable,
universally agreed protocol for carrying out such long term tests
currently exists," Janet Cotter of Greenpeace International's
science unit told AFP in an email.
"Even then, such
tests will not address the broader environmental and social
implications," she said.
The European Food
Safety Agency (EFSA), which reviews use and authorisation of GM
organisms, has rejected the Seralini report as "inadequate;"
its final judgement is expected in "the coming weeks," the
agency said on Monday.
Watchdogs in Germany
and Australia and New Zealand have also said the study offered no
firm evidence of risk.
Seralini is a
well-known opponent of GM food.
But his paper appeared
in the journal, Food and Chemical Toxicology, which uses the
peer-review process, a system designed to ensure published research
is accurate and fair.
Greenpeace
warns EU off herbicide-tolerant GM crops
Warsaw (AFP) Oct 22, 2012 - Global environmental watchdog Greenpeace launched a new report Monday warning the European Union against authorising herbicide-tolerant genetically engineered (HTGE) crops, saying they would lead to herbicide-resistant super-weeds.
"When
herbicide-tolerant crops are relied on heavily, they trigger the
spread and emergence of resistant weeds, which has now happened
throughout the United States," said Oregon-based agricultural
economist Charles Benbrook, who was commissioned by Greenpeace to
study the issue.
"Then
farmers have to spray much more heavily, turning to older,
higher-risk herbicides which increases risk to both their cost of
production as well as the public health problems associated with
herbicide use," Benbrook told AFP, adding: "We're solidly
in that phase in the US."
The
launch of the report in Warsaw, Poland comes as the 27-member EU
considers authorising 26 genetically engineered crops, including 19
that are tolerant to herbicides, Greenpeace said.
Benbrook
has predicted EU farmers risk using up to 15 times more
glyphosate-type herbicides on HTGE corn, soy and sugar beet crops to
stem the growth of super-weeds over a 14-year period (2012-2025), as
well as inflated prices for genetically modified seeds, should
Brussels allow them.
Greenpeace
commissioned Benbrook to complete a study on glyphosate-tolerant
crops in the EU based on data on use of the herbicides in the US.
US
biotech giant Monsanto brought glyphosate to the market in the 1970s
under the Roundup trademark, but it is now off-patent and has become
the most commonly used herbicide in the US.
While
its producers claim glyphosate has relatively low toxicity compared
to other herbicides, concerns persist about its environmental and
human impacts.
"If
EU farmers take up HTGE technology as quickly as in the US,
glyphosate use in maize crops -- the most important and widely grown
crop in Europe - will increase by over 1,000 percent by 2025 over
current use, and total herbicide use will double," Greenpeace
warned in a Monday statement quoting the Benbrook study.
Benbrook
and two US farmers are on an 18-day Greenpeace tour of Europe to meet
farmers, local communities and politicians to share their concerns
about HTGE crops.
