Will Enviropigs Make It To Toronto?

Posted by Lauren / February 25, 2009

University of Guelph EnviropigsSo I hear game is the new pork. No wait, pork is the new pork. At least that's what researchers at the University of Guelph are hoping to find with their genetically engineered wonderhog, the "Enviropig".

The Enviropig is a special little piggy, one who excretes up to 60-75% less phosphorus in its piggy poop. This is important, because last year in Ontario alone 3.9 million hogs were raised, each producing about 900kg of waste. This waste is often spread on farmland as a fertilizer.

The excess phosphorus present in most pig feces makes its way through the soil and what isn't used by plants gets into ground water, and eventually into bodies of water. Once there, the phosphorus encourages the rapid growth of algae; algae that hogs the water's oxygen supply and causes fish kills.

The Enviropig was first developed in 1999 by University of Guelph researchers when they spliced together a gene from mice responsible for salivary excretion and a phytase gene from a non-pathogenic strain of E. coli to create a transgene, also known as a recombinant DNA (rDNA) construct.

The rDNA construct was then injected into pig embryos and implanted into surrogate mothers. The groundbreaking research was funded by Ontario Pork, a trade association made up of 2,900 pig farmers.

On January 15th the U.S. Food and Drug Administration (FDA) released final guidelines for industry on the regulation of genetically engineered (GE) animals, meaning that this Enviropiggy could go to market in the foreseeable future. But as the guidelines stand, product labeling for GE animals would for the most part be voluntary.

There is not yet a Canadian regulatory framework for genetically engineered animals, however Health Canada is in the process of developing a guidance document.

Even if these GE pigs, (and any other GE animal that now has the potential to be commercialized) make it to market here in Toronto, is anyone going to actually eat them?

Consumer polls generally show that people are not all that interested in eating GE meats, and if they were to come to market the vast majority agree that they should be labeled.

In fact, natural foods retailer The Big Carrot has launched the "Non-GMO Project" that has phased out all genetically engineered products from its store, and requires suppliers to prove that their products are GMO-free.

And stores like the Healthy Butcher that sell all organic meats won't be interested in the Enviropig either, as organic standards prohibit the use of GMOs. Owner Mario Fiorucci also disagrees with voluntary labeling of genetically modified meat. "The FDA is not requiring the label to say that a product is genetically modified. Why is that? Are they afraid that people won't buy that product? If so, then why allow it in the first place."

Additionally, environmentalists and proponents of organic farming argue that innovations such as the Enviropig are merely band-aid solutions for an otherwise broken industrial production system.

Dr. Rod MacRae from the Faculty of Environmental Studies at York University explains: "The enviropig is designed to attenuate one of the problems of the industrial model, but it in no way fits within an ecological design. Certainly hogs excrete a fair bit of phosphorous, but that's only a problem when you've got way too many of them on a limited land base, and you've already got soil with too much phosphorous in it. So, it's a risky strategy to employ for minimal gain, given that it fails to address any of the design flaws of industrial hog operations."

So what is the fate of this little piggy in Canada? Will it get to market? And the bigger question is, if it does will anyone care?

This is disgusting. Do you know what else would prevent excess levels of "deadly" (natural) phosphorous to be produced? Ending factory farming.

Do we Canadians really need to eat 3.9 million pigs a year? Why is our first option to change the genetic makeup of an animal, rather than question the way we're consuming?

Much of the fear surrounding GMOs is completely unfounded. The vast majority of what we eat is been genetically altered in some way.

Take carrots for example. Did you know carrots used to be purple? Orange carrots were created when the Dutch (those wonderful genetics masters) selectively breeded and cultivated the purple variety until they became orange, in honour of the Royal family at the time.

The biggest danger with GMOs are the corporations involved in their manufacture. When companies like Monsanto genetically enginneer their Corn or Soy and patent it, it's not so much a health or environmental problem as it is an economic one. They've been using their patents to take almost complete control of the American agriculture system (it's marginally better here in Canada). The system hurts small farmers and favours large agribusiness, which in turn is bad for the environment and our health. But it's not the GMO at fault, just the patent system and greed of these large companies.

I think genetic engineering through selective breeding is completely different than splicing mice, e. coli and pig together in a petri dish. One is a legitimate farming practice, the other is science gone stupid.

I wouldn't say that the fears are unfounded. We have absolutely no idea what the effects of the later form of GMOs are. Selective breeding generally maintains the genetic makeup (i.e. orange carrots are still all carrot, no mice genes spliced in). Modern day GMOs include genes spliced in from who knows where.

But you do raise a good point about the economic issue of companies like Monsanto "creating" and then patenting GMOs. Monsanto's invention of so-called "terminator seeds" (seeds for plants which are genetically engineered to die after one harvest, rather than regrow the next year) are an attempt to maximize profits while weeding out small farming operations. Greedy, predatory and completely backwards.

I always hear these stories of animal genes being spliced into our vegetatbles, but they simply aren't true. Tests have been made with animal genes, but the only thing that has made it to our food system has been merely plants spliced with other plants. The stuff they are doing with gene splicing in the lab is very, very similiar to the sort of stuff they were doing before with cross breeding.

The old system actually made it tougher to get the desired effect without unwanted side effects. They still cross bred different plants together and they still created plants that were resistant to pesticides and herbicides.

If you're not a fan of the industrial agriculture system, that's fair, but really, the GMO crops aren't really any different than the other industrial agriculture crops.

Come on, Amy, you know that people don't really want to take a good hard look at their own lives when there are easier, less intrusive, answers out there. We now have hybrid cars like the Prius that allow us to drive to the corner store guilt free rather than walk or bike. Why make the effort to change yourself when you can get by being green-washed?

Too true, too true. Corporations make money marketing a "green" product, consumers pay a few extra bucks to appease the inner environmentalist and alleviate the feeling of guilt, and then it's all business as usual.

Leaving aside environmental concerns and even the welfare of the pigs themselves, what kinds of effects will less phosphorus have elsewhere?
As a fertilizer component, phosphorus is extremely important, especially for flowering plants. It's also critical in the production of organic phosphates and all sorts of other vital function.
GMO foods may be deemed safe for human consumption (let's assume Monsanto doesn't want to kill/harm all of its customers), but there are *many* knock-on effects (many of them major) which don't seem to enter the discussion.
These are also environmental and, as has been the case with some items, the secondary/tertiary effects of a "green" products are much worse than the original problem they were created to address.
I don't want to make the case against potentially beneficial developments (food or otherwise), it's just that this type of evaluation is very myopic (and, sadly, prevalent).

Lauren, this article really made me think. I find it particularly curious that The Big Carrot as taken the stance that 'GMO = Bad'. Is this universally true? I'm, myself, not sold on that line of thinking; but am admittedly conflicted.

Thanks for this post, it's very informative. I wasn't aware of this although I must say, I strongly disagree.

has anyone eaten these pigs
what do they taste like pork i guess
great work i take my hat off to creators of enviropig
in australia we have trouble with poisonous plants in cattle country
if you guys can have a look this problem
would open up a lot of country that isn't used now

Wont eat enviropigs! / January 13, 2010 at 11:30 pm

Enviropigs are very ecofriendly, c'mon, 50-60% less phosphorus that's a good sign. Would phosphorus harm us? Where does phosphorus come from? Would anyone be confident in eating these things? Just because they're ecofriendly doesnt mean theyre stomach friendly. If ya'll know what i mean. Who's gonna test these new "creations"? Us? Scientists? We should know if its safe to eat not just safe for the fields and water....Great work, ya'll did good.
