Next spring, farmers in Canada will be able to sow one of the most complicated genetically engineered plants ever designed, a futuristic type of corn containing eight foreign genes.
With so much crammed into one seed, the modified corn will be able to confer multiple benefits, such as resistance to corn borers and rootworms, two caterpillar-like pests that infest the valuable grain crop, as well as withstanding applications of glyphosate, a weed killer better known by its commercial name, Roundup.
But a controversy has arisen over the new seeds, which were approved for use last month by the Canadian Food Inspection Agency: Health Canada hasn't assessed their safety.
The health agency said in response to questions from The Globe and Mail that it didn't have to do so, because it is relying on the two companies making the seeds, agriculture giants Monsanto Co. and Dow AgroSciences LLC, to flag any safety concerns. But the companies haven't tested the seeds either, because they say they aren't required to.
The companies have checked the safety of each of the eight genes one at a time in individual corn plants, but haven't done so when they combined the foreign matter together in one seed, says Trish Jordan, a spokesperson for Monsanto Canada Inc.
"Every single one of the traits has been tested singly, and it has gone through the complete rigorous regulatory review process," Ms. Jordan said.
When the eight traits were subsequently combined into one seed through conventional breeding techniques, there was no trigger for an additional safety assessment, she said.
But the companies', and Health Canada's, position is disputed by opponents of genetically modified foods and consumer safety advocates, who say guidelines from the UN's food standards commission, Codex Alimentarius, recommend such testing, even when the novel traits are introduced through normal plant breeding.
Michael Hansen, senior scientist at Consumers Union, a U.S. advocacy group, says he's worried that combining a large number of foreign genes could lead to the creation of allergens or other deleterious substances in food that don't occur when only one gene is involved.
The government's decision to leave the safety testing to the companies is like "putting the fox in charge of the hen house," Mr. Hansen said.

Honestly, anything that Dow and Monsanto do scares the crap out of me. For some reasons why read this. Or go see FoodInc or just google Monsanto and Dow. Seriously insane stuff.
