GMO pigs' cautionary tale of genetically modified food research

Genetically modified corn and canola are just a couple of examples of common GMOs. Now science is making strides toward genetically modified animals to add to our diet.

Once upon a time, there were three little genetically modified pigs, each modified in its own special way...

For decades, genetically modified crops such as corn and canola have been a common -- if still controversial -- part of Canada's food system. 

Now, new advances in genetic modification are poised to make it possible to put genetically modified animals on our dinner plates as well. 

GMO Pig

The enviropig looks and sounds just like a normal pig. But it is different, genetically. To create this pig, scientists have added an ecoli bacteria gene and mouse DNA to a normal pig embryo. (Thomas. Flickr cc)

To date, Health Canada has not approved any genetically modified animals for human consumption. But an American company looking to produce salmon genetically engineered to grow faster is seeking approval to sell its product. 

And in Britain, researchers are making great strides towards a pig genetically engineered to be resistant to African Swine Flu, a disease that routinely devastates pig populations across Europe. 

It's not the first attempt at genetically modified pork. The first little piggy didn't make it to the market. But it almost did. The goal of the enviropig was to to genetically engineer a pig to be more environmentally friendly by reducing the amount of phophorus it produces.

Are you concerned about genetically-modified foods, or do you think some of the fear is misplaced?
