Genetically modified food has been available on the Canadian market since the mid-1990s. Many foods fit in the category, such as cereal, high-fructose corn syrup and soy milk; they are derived from agricultural crops that have been genetically manipulated to increase production. The Canadian government has approved over 100 different genetically modified crops for use as raw material for human food consumption, cattle and farm feed, and fibers.
Genetically Modified Corn
This is corn that has been genetically modified for pest resistance. These varieties of corn contain a synthesized gene; the corn then produces an insect-control protein that acts as a pesticide. A second protein has been inserted that allows for researchers to track and identify the plants.
Roundup Ready Soybeans
These are soybeans that are resistant to herbicides, specifically, Monsanto's Roundup. Roundup Ready soybeans have a single bacterium gene inserted into them that prevents the soybean from absorbing glyphosate, Roundup's active ingredient.
Potatoes
The genetic modification of these potatoes protects the plants from the Colorado Potato Beetle, a common pest in Canadian agriculture. Two bacteria genes have been inserted into the potato plants, producing two proteins. One gene/protein combination protects the plant while the other combination allows researchers to identify the plants.
Flavr Savr™ Tomato
These tomatoes have been modified to slow the tomato's ripening process. The slower ripening allows for the tomato to have a stronger flavor. A gene has been reversed in the tomato that slows the process. A second gene has been modified to produce a biological marker that allows researchers to track and identify the plants.
