'SmartStax': No Safety Assessment from Health Canada
Summary: On July 15, 2009 Monsanto and Dow AgroSciences announced that they received approval to introduce their new eight-trait GE corn 'SmartStax' into Canada and the US. But Health Canada did not assess 'SmartStax' for human health safety and did not even bother to authorize it. The Canadian Food Inspection Agency authorized the environmental release of 'SmartStax' but never conducted an environmental risk assessment and actually substantially weakened its environmental stewarship rules for the crop. Because the eight traits have previously been approved in separate crops, Canadian regulators do not see anything new in combining the eight together in one crop - despite the fact that the Codex international food safety guidelines that Canada helped to negotiate clearly state that stacked traits can lead to unintended effects and should be subject to a full safety assessment.
What is SmartStax?
SmartStax is a genetically engineered (GE or genetically modified, GM)
corn that is unique because it is has eight GE traits combined or
‘stacked’ together – 6 for insect resistance (Bt) and 2 for herbicide
tolerance. There are some stacked GE trait crops on the market already
but these only have up to 3 traits each.
‘SmartStax’ was created through a research collaboration between
Monsanto and Dow AgroSciences so that the two corporations could share
their GE traits. Monsanto and Dow are predicting that ‘SmartStax’ will
be the largest ever commercial launch of a GE corn because it will
replace a lot of the existing GE corn on the market.
What's the problem with 'SmartStax'?
There are many serious problems with ‘SmartStax’ including new
potential environmental and health risks, all exacerbated by the
Canadian government’s refusal to assess the new risks of GE stacked
Health Canada did not assess the safety of ‘SmartStax’:
Health Canada did not conduct a safety assessment for ‘SmartStax’. The
department has chosen to exempt stacked trait GE crops from its already
weak biotech safety assessments. Health Canada has approved the eight
traits separately, in the past, and does not see anything new in
combining the eight traits together. This is not consistent with the
international guidelines that Canada has negotiated at Codex. Codex
guidelines are recognized under the World Trade Organization (WTO) and
are used to settle trade disputes. Codex is clear that foods from
stacked crops with stacked GE traits should go through a full safety
assessment for new unintended effects. Health Canada did not do this
and does not even list the ‘SmartStax’ corn on its website as a new GE
The insecticidal toxins in Bt crops show similarities to proteins that
cause food allergies. In 2000/2001, a Bt corn known as ‘StarLink’ was
approved in the U.S. only for animal feed because of concerns it could
cause food allergies. When it massively contaminated the U.S. food
supply, hundreds reported allergic reactions, and the subsequent
investigation was never able to determine the cause. ‘SmartStax’, which
contains 6 insecticidal toxins, will mean greater human exposure to
insecticidal toxins that may be allergenic.
The Canadian Food Inspection Agency did not conduct an environmental risk assessment:
The Canadian Food Inspection Agency (CFIA) authorized the environmental
release of ‘SmartStax’ but did not assess its environmental risks.
Normally, the CFIA (like Health Canada) posts “Decision Documents” to
summarize their approval decisions – but there is no such document for
‘SmartStax’. This implies that no environmental risk assessment was
done. There is no public rationale for why the CFIA approved
‘SmartStax’ without environmental risk assessment.
The Canadian Food Inspection Agency dramatically weakened the environmental rules for ‘SmartStax’:
For ‘SmartStax’, the CFIA has reduced the required size for refuge areas from 20% to 5% - that’s a 75% reduction!
Refuge areas are a strategy to delay the evolution of insect resistance
to the Bt toxin. A refuge is part of a field that is planted with a
non-Bt variety of the same crop, to ensure that some insects remain
susceptible to the Bt toxins.
Bt (Bacillus thuringiensis) is a naturally occurring soil borne
organism that can be used topically by organic farmers to control
pests. The genes from Bt have been genetically engineered into corn to
make the plant act as a pesticide. Bt crops are speeding the
development of insect resistance to Bt, something that is seen as
inevitable, because they express the Bt toxin in every cell, all the
Farmers who plant GE insect resistant (Bt) corn must plant a 20% refuge
of non-Bt corn within one-quarter mile of any Bt field. But with
‘SmartStax’ the area has been reduced to only 5%. The CFIA did not
provide a rationale for this major reduction in its already extremely
weak environmental stewardship rules for GE crops.
Monsanto has increased control in the seed market:
It is expected that ‘SmartStax’ will soon replace all of Monsanto's
single, double and triple stacked GE crops. This means that farmers who
do buy GE seeds will only be able to buy ‘SmartStax’, at a higher
price. For example, a farmer who wants to buy Monsanto’s herbicide
tolerant technology will have to buy seeds that incorporate other
traits like Bt for insect resistance as well.
Monsanto’s increasing control over the seed market is also clearly seen
in a trend where seed companies are selling fewer and fewer non-GE
seeds. For example, of the 40 varieties that Pickseed had available for
sale this year, only 5 were non-GE.
Monsanto has increased profits:
Stacking traits together in one crop means that corporations like
Monsanto can make even more money because farmers are buying even more
patented technology. Monsanto and Dow are already saying that they
could add even more GE traits to ‘SmartStax’.
The new reduction of the refuge area for ‘SmartStax’ from 20% to 5% also means that Monsanto can sell 15% more ‘SmartStax’ seed.
GE Insect Resistant Crops Unnecessary:
Today, Euroepan Corn Borer and corn rootworm are not serious pests in
most corn fields in Canada. The U.S. based Union of Concerned
Scientists has shown that yield increases in corn are due to
conventional breeding, while the Bt insect resistance trait only
reduces yield losses on those infrequent occasions of heavy pest
infestation. Bt corn has not significantly reduced pesticide use
because few farmers ever actually sprayed for the European Corn Borer.
The Canadian Biotechnology Action Network advocates the immediate
recall of authorization for ‘SmartStax’ in Canada and a moratorium on
all new approvals of GE crops and foods until there is a comprehensive
reform of the entire regulatory system in Canada.
CBAN has written to Health Canada to demand that:
* Health Canada immediately request that the Canadian Food Inspection Agency to rescind its authorization of the genetically engineered (GE) eight-trait corn called ‘SmartStax’ (Monsanto and Dow AgroSciences)
* Health Canada initiate a full food safety assessment of the GE corn as set out by the Codex Alimentarius Guideline for the Conduct of Food Safety Assessment of Foods Derived from Recombinant-DNA Plants.
* Health Canada request the Canadian Food Inspection Agency to halt any further approvals of stacked trait products until such time as Health Canada has reviewed its Novel Foods Regulations and initiated a system-wide review of the entire regulatory system for GE foods and crops (Novel Foods and Plants with Novel Traits).
Details: The international Codex Alimentarius Guideline for the Conduct of Food Safety Assessment of Foods Derived from Recombinant-DNA Plants clearly recommends safety assessments of stacked trait GE crops. The Guideline clearly states that unintended effects can arise not only from genetically engineered (GE) plants, but can also arise when those GE plants are crossed via conventional breeding (as in the case of stacked-trait crops such as ‘SmartStax’): “Unintended effects in recombinant-DNA plants may also arise through the insertion of DNA sequences an/or may arise through subsequent conventional breeding of the recombinant-DNA plant” [bold added] (para 14, CAC/GL 45-2003).
Furthermore, the Guidelines also state that such crops should go through a full safety assessment: “The assessment for unintended effects takes into account the agronomic/phenotypic characteristics of the plant that are typically observed by breeders in selecting new varieties for commercialization. These observations by breeders provide a first screen for plants that exhibit unintended traits. New varieties that pass this screen are subjected to safety assessment as described in Sections 4 and 5” [bold added] (para 17, CAC/GL 45-2003).
