Stop 2,4-D and dicamba tolerant GM crops

Canada has approved 2,4-D-tolerant GM corn and soy. On October 15, 2014, the US government also approved Dow's 2,4-D/glyphosate herbicide mix, to go along with GM 2,4-D tolerant crops. Now Dow AgroSciences has all the approvals it needs to start marketing these GM herbicide tolerant crops in Canada and the US.

“Get GM Sweet Corn Out”

Is your sweet corn genetically modified? The only way to find out is to ask. You have a powerful voice when you ask your local farmer or write to the head office of your grocery chain.

1. Ask your farmer at the roadside, farm gate, or farmers’ market if they are selling GM sweet corn. You can even ask the Farmers’ Market to check for you.
2. Write to the head office of your grocery store and ask them to remove GM sweet corn from their store. Tell them you don’t want to buy it. Click here to for grocery store contacts.
3. Buy organic sweet corn – organic farming prohibits GM seeds and synthetic pesticides.

Your consumer action is very influential!

Tests Find Unlabelled GM Sweet Corn

Press Release, February 26, 2014: Consumer Concern Over GM Sweet Corn Mounts

Press Release - November 14, 2013: New study: GMO sweet corn rare in U.S. supermarkets

Update, November 14, 2013: Further to tests conducted by CBAN, Friends of the Earth U.S. released the results of their tests on sweet corn samples. Tests of sweet corn purchased in the U.S. did not find any GM sweet corn except for two samples, one from Ontario and one of unknown origin. “We were alarmed to find a significant amount of GM sweet corn in Canada, and are shocked that Canada could actually be a source of genetically engineered sweet corn to U.S. consumers," said Lucy Sharratt, Coordinator of CBAN.

October 23, 2013: The Canadian Biotechnology Action Network (CBAN) tested sweet corn samples from across Canada and found unlabelled genetically engineered (also called genetically modified or GM) fresh sweet corn in grocery stores, roadside stands and farmers markets. CBAN testing clearly shows that consumers across Canada could be unknowingly buying GM sweet corn. Press Release - October 23, 2013: Tests Discover Unlabelled GM Sweet Corn in Canadian Grocery Stores and Farmers’ Markets

What CBAN Tests Found (2013):

  • GM sweet corn was discovered in samples purchased from Loblaw stores.
  • GM sweet corn was also present in samples from farmers markets and roadside stands.
  • Various samples from all 4 provinces where samples were collected - Ontario, BC, Nova Scotia and Alberta - tested positive.
  • Testing of samples from Sobeys and Walmart did not find GM sweet corn.
  • No samples were tested from Metro stores.
  • Results are not statistically significant but provide a snapshot of GM sweet corn in Canada, in the absence of mandatory GM food labelling and any government tracking, including statistics on GM crop cultivation.
  • The tests were conducted by CBAN staff using strip tests for the GM protein Cry1Ab.

The Testing:

The purpose of CBAN’s test was to get an indication of the presence of genetically engineered sweet corn in grocery stores, and at roadside stands and farmers markets in Canada. CBAN tested 43 fresh, conventional sweet corn samples from across the country, at the end of the 2013 season. Half of these were from Ontario, with the rest from BC, Alberta and Nova Scotia. The corn samples were purchased from outlets of the major grocery store chains (Loblaw, Walmart and Sobeys) as well as from some smaller independent grocery stores, farmers markets, and roadside stands.

“Our sample size was small and random but shows a clear presence of GM sweet corn, across provinces and various types of vendors,” said CBAN researcher Taarini Chopra, “The results don’t tell us how much of Canada’s sweet corn is GM, but they do tell us that it’s out there, in both grocery stores and farmers markets.”

CBAN staff conducted the tests at the laboratory of Seeds of Diversity Canada in Waterloo, Ontario, using strip tests for the GM protein Cry1Ab (for insect-resistance).

GM Sweet Corn in Canada:

There has been a small (undetermined) amount of GM sweet corn, from Syngenta, on the market for over 10 years in North America. However, in late 2011 Monsanto launched a line of GM sweet corn varieties as well.

GM sweet corn is the only whole GM food that is grown in Canada - as opposed to GM field corn, which is processed into food ingredients, animal feed and biofuels.

GM sweet corn is the third possible GM fruit or vegetable in the produce section of Canadian grocery stores. There could be some GM papaya (from the U.S. and China only) and some varieties of GM squash (from the U.S. only) that end up on grocery shelves in Canada.

The sweet corn is genetically engineered to be both insect-resistant and herbicide-tolerant.

Farmers may be planting GM sweet corn without knowing that it is genetically engineered because seed catalogues do not label GM varieties.

More Information

GM sweet corn is engineered to be toxic to particular insects. The GM technology transforms the corn plant into a pesticide. In fact, the toxin, from the soil bacteria Bacillus thuringiensis or Bt, is expressed in every cell of the plant including the corn kernels. If certain insects, including the European corn borers, corn earworms, fall army worms and corn rootworm larvae, try to eat the corn, they will die. The Bt toxin attaches to receptors in the gut of some insects, rupturing the gut and killing the insect.

"SmartStax" Eight-Trait GE Corn

The GM SmartStax corn produces six different insecticidal toxins and is tolerant to two herbicides. It was allowed onto the market in Canada without a safety evaluation from Health Canada.

Background: Health Canada did not assess the safety of “SmartStax” GM corn. Health Canada does not classify “SmartStax” as a “Novel Food” because it has previously approved the eight single GM traits in “SmartStax”, individually in earlier crops. Health Canada says that combining eight GM traits together does not create any new risks and does not need any safety evaluation. Health Canada did not even bother to rubber-stamp “SmartStax” – it was approved for release by the Canadian Food Inspection Agency, without Health Canada.

Summary: On July 15, 2009 Monsanto and Dow AgroSciences announced that they received approval to introduce their new eight-trait GM corn 'SmartStax' in 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 stewardship rules for the crop. Because the eight traits were previously approved in separate crops, Canadian regulators do not see anything new in combining the eight together - 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.

Failure of Government Regulation

CBAN demands that:

  • Health Canada immediately request that the Canadian Food Inspection Agency rescind its authorization of the genetically modified (GM) eight-trait corn called ‘SmartStax’ (Monsanto and Dow AgroSciences)
  • Health Canada initiate a full food safety assessment of the GM 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 halt any further approvals of stacked trait products until Health Canada has reviewed its Novel Foods Regulations and initiated a system-wide review of the entire regulatory system for GM foods and crops ("Novel Foods" and "Plants with Novel Traits").

The UN Codex guidelines for GM food safety assessment state that “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.’’ (this is how stacked trait GE crops like ‘SmartStax’ are produced – through the conventional breeding or crossing of GM plants) and that such crops should go through a full safety assessment (para 14, CAC/GL 45-2003).

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).
