'Frankenfish': food's future

There is nothing rational about irrational obsessives

DESPITE evidence to the contrary, campaigners against genetically modified (GM) food continue to feed consumers stories about risks to health or ecology - to the detriment of long-term food security, writes DAVID LEYONHJELM.

CANADIAN authorities recently approved commercial scale production of genetically modified (GM) salmon eggs. The fish that they become cannot yet be sold to the public as food, but it is intended that day will come.

The fish are Atlantic salmon containing an extra gene from Chinook salmon. The gene enables them to grow twice as fast as non-GM salmon.

Fish farming has a bright future. Health experts recommend we eat more fish to reduce heart disease and obesity. Wild fisheries cannot sustain the catch levels needed to meet growing demand, so it makes eminent sense to commercially farm them.

But fish farming is not something that just anyone can do. Like any type of farming, economic viability requires efficiency. Indeed, in its early days fish farmers lost a lot of money as they struggled to understand the variables and to drive down costs to allow them to compete with wild fisheries.

Through improved knowledge and technology, production costs are now at a point where quite a range of species can be profitably farmed. But fish farms also compete with each other, both domestically and internationally, just like farms that grow soybeans, cattle or carrots. So there is never any letup in the quest for increased productivity.

Besides saving wild fisheries, more efficient fish farms can have other environmental benefits too. Because excreta from fish farms are a source of pollution in coastal waters, those with greater feed conversion efficiency will utilise less feed, leading to less waste and less excreta for each tonne of fish produced.

In the future, fish may be genetically modified to reduce the environmental impact of their excreta. I mention this because it is already a reality with pigs. A strain of pigs in Canada has been engineered with genetic material from a mouse to reduce phosphorous in its faeces.

Known as the Enviropig, these pigs excrete 20-60 percent less phosphorus than normal pigs. Phosphorus in piggery waste can be quite a problem if it leaches into ponds, streams, and rivers because it stimulates increased algal growth and has other adverse effects.

Unfortunately for those concerned with the health of waterways, anti-GM activists mounted such a fierce campaign against the Enviropig that the program was halted prior to commercialisation. Its major commercial supporter withdrew support in 2012 and the University of Guelph killed the pigs, from the 10th generation of the project, when it couldn’t find a new partner to fund the project.

Had the Enviropig made it onto the market, it would have become the first genetically engineered animal in the food system. The fast-growing salmon may now have that honour.

Already the opponents are preparing to prevent that though. The term “frankenfish” is being bandied about and there are wild claims that the fish will escape fish farms and endanger wild Atlantic salmon. The claim of insufficient testing is being made, a claim that is still made today despite genetically modified crops being grown commercially for 20 years.

There is an entire industry fixated on preventing food from genetically modified sources from reaching our plates. Australia’s own veteran anti-GM campaigner, Bob Phelps, has made a career of it for more than 20 years. The mere mention of genetic modification is sufficient, without needing to know more, to prompt some people to froth at the mouth.

The problem is not that these people are obsessed, but that they inflict their obsessions on society by convincing politicians and regulators that they represent mainstream opinion. They invent scary stories, mislead the media, enlist gullible politicians and public figures, and frighten off investors with threats of boycotts and other direct action.

Because of them most of Europe thinks food from genetically modified sources is bad for human health, the environment or animal welfare, or all of the above, contrary to all scientific evidence. So bizarre has it become that the EU won’t even buy GM canola to convert into biodiesel for use in cars and machinery.

At the same time there are no concerns about the use of genetically modified organisms to produce vaccines, insulin or other pharmaceuticals, whether for humans or animals, or the use of genetically modified rennet in the production of cheese. There is nothing rational about irrational obsessives.

By any objective measure Canada’s genetically modified fish should be welcomed with open arms. It will make a healthy fish diet cheaper and more readily available, while relieving the pressure on wild fisheries.

Of course the risks will be fully considered by experts prior to it being approved for human consumption, but there is nothing inherently hazardous about eating a piece of salmon with DNA from both Atlantic and Chinook species. You could just as easily consume a meal comprising a separate piece from each.

If they escaped from a fish farm and were capable of breeding with wild fish (which may not be the case), they would only grow faster if the same level of food was available as in a fish farm. That is not likely. And so what if they grow faster anyway?

But whether the public, media, politicians and regulators recognise the benefits, or are swayed by the anti-GM obsessives, is far from certain. If the history of GM crops is any guide, we are in for a long, tortuous battle.

Well David I'll say this for you, You certainly know how to stir the pot ! The one point you ALWAYS miss is the concentration of power / production to a very small group. You should give all the facts--------if you know them. There should be a Royal Commission into the whole GM bit. Then the TRUTH will come out and we can make an informed decision.

I just want to be able to choose non-GM because I don't trust our "scientific" spokes-people. Any senior manager or politician statement is automatically interpreted as a lie until proven otherwise. Commercial interests in our society over-ride public interest and common sense.

Gene shifting within a genus is not uncommon in nature as well. Note the Mule and the Liger, but also innumerable crosses in the fruit and vegetable sector (particularly stonefruit) This begs a more complex question where the sophistication around so called GMO is increasing. What can be the objection to GM sugar cane when the only exposure to humans is sucrose (which remains sucrose whatever its origins). The same can be said for many of the oils. What if a plant produces conventional varieties from vines grafted to GM rootstock? How can the product be branded GM when it clearly is not!

There is "smart" GM and plain dumb GM. The "smart" GM is using what is out there to help nature along its way. What they have done in Canada is an excellent example. Same as if a particular DNA from one plant helps another plant resist disease or pest attacks. Reduction of use of chemicals - great outcome. But not to add a gene from one source into another just to make it glow in the dark to make it easier to harvest - that's dumb. To make a tomato or apple reder - that's dumb. Making plants use mositure uptake better, take up nutrients better, to convert sunlight into stored energy.

Didn't scientists of the time tell us the cane toad would be a good answer to the cane beetle and that feeding meat to cows would be ok? I'm betting GM will also have some unintended consequences. Please just label GM food so I can choose not to buy it.

David, all you seem to write about is articles against free range chickens and for GM food. Why hasn’t any journalist in Aust covered the signing up to the Trans Pacific Partnership which will give US firms the ability to sue the Aust government if we put in laws that impact the sale of their product e.g. similar to the case of Philip Morris suing the govt for having plain cigarette packages.

CV...give you the one on cane beetle...but in the overall scheme of things BSE is a blow-up out of all proportion (PR own goal aside). Also what about Cactoblastis, Myxo and Calici as well as a number of beneficials in IPM...scientists sometimes get it wrong but often get it right. Current GM research as described above is not anywhere near the Frankenfood scale...just good science at work for good outcomes

Hydatid, vertical gene shifting may be possible and successful in nature, but not horizontal gene transfer. Huge difference in outcomes. Also David's blase description of swapping genes (really? mouse genes in pigs???) I wonder what generational testing was done to show the safety of this experiment, if any? We have moved on from Crick's law of genetics, and the central dogma of one gene equals one protein is history, didn't you realise David?
