The Omega Pig

Bring Home the Biotech Bacon

SAN FRANCISCO -- A microscopic worm may be the key to heart-friendly bacon.

Geneticists have mixed DNA from the roundworm C. elegans and pigs to produce swine with significant amounts of omega-3 fatty acids -- the kind believed to stave off heart disease.

Researchers hope they can improve the technique in pork and do the same in chickens and cows. In the process, they also want to better understand human disease.

"We all can use more omega-3 in our diet," said Dr. Jing Kang, the Harvard Medical School researcher who modified the omega-3-making worm gene so it turned on in the pigs.

Kang is one of 17 authors of the paper appearing Sunday in an online edition of the journal Nature Biotechnology.

The cloned, genetically engineered pigs are the latest advance in the agricultural biotechnology field, which is struggling to move beyond esoteric products such as bug-repelling corn and soy resistant to weed killers.

Hoping to create healthier, cheaper and tastier products that consumers crave, Monsanto of St. Louis and its biotech farming competitors like DuPont are developing omega-3-producing crops that yield healthier cooking oils. Kang said 30 academic laboratories are now working with his omega-3 gene, presumably pursuing similar projects.

"Consumers have responded pretty positively when asked their opinion of food modified to improve food quality and food safety, just as long as the taste isn't altered negatively," said Christine Bruhn, director of the Center for Consumer Research at the University of California, Davis.

Earlier experiments have succeeded in manipulating animals' fat content but most never made it out of the lab because of taste problems.

While boosting Omega-3s doesn't decrease the fat content in pigs, the fatty acids are also important to brain development and may reduce the risk of Alzheimer's disease and depression. The American Heart Association recommends at least two weekly servings of fish, particularly fatty fish like trout and salmon, which are naturally high in omega-3s.

People already eat genetically engineered soy beans in all manner of processed food, but biotech companies run into what bioethicists call the "yuck factor" when they begin tinkering with animals.

The Food and Drug Administration has never approved food derived from genetically engineered animals. Unlike crops, the FDA treats such animals as medicine and requires extensive testing before approval.

"We understand that this research is in the very early stages," FDA spokeswoman Rae Jones said. "This technology will not likely reach meat counters for many years."

The FDA is still considering Massachusetts company Aqua Bounty Technologies' application to market a salmon genetically engineered to grow faster, the only such request pending with the agency. Aqua Bounty began its federal application process about nine years ago and there is no indication when the FDA will rule.

In the meantime, the researchers of the latest project said they will use their genetically engineered pigs to study human disease, especially heart conditions.

How very nice, especially since I hate almost all types of fish there are.

But but but you can't play god with food! It's not natural! We should eat everything raw and uncooked as NATURE intended!

(fucking hippies)

I'm just wondering what other genes got screwed up from this. We really don't know what can happen

This wouldn't make bacon good for your heart though. While you might stave off heart disease, I still think you'd be vulnerable to clogged arteries and the like.

Wait a minute, aren't clogged arteries a symptom of heart disease? Man, I am not thinking clearly today.

That doesn't mean we can't find out. I'm in favour of GM food so long as responsible scientific bodies can thoroughly examine all non-negligible consequences of a strain. If megacorps are in charge, there's obviously a conflict of interest. We have to use our brains to foresee problems, rather than Mother Nature's method of 'oops, that species got decimated, see you in a million years'. I'm not well-versed in the topic, but i do know the potential benefits are enormous.
