Genetically altered salmon? It doesn't stop there

By SETH BORENSTEIN and MALCOLM RITTER (AP)

" ......... Whatever the decision on salmon, it's only the start of things to come. In labs and on experimental farms are:
_ Vaccines and other pharmaceuticals grown in bananas and other plants.
_ Trademarked "Enviropigs" whose manure doesn't pollute as much.
_ Cows that don't produce methane in their flatulence.
And in the far-off future, there may be foods built from scratch — the scratch being DNA.
Sometimes when science tinkers with food, it works. Decades ago, Norman Borlaug's 'Green Revolution' of scientifically precise hybrids led to bigger crop yields that have dramatically reduced hunger.
Sometimes it flops. Anyone remember the Flavr Savr tomato? Probably not. It didn't taste good. 'There was no flavor there to save,' one expert quipped. But you might remember 10 years ago when genetically modified corn meant for animal feed wound up in taco shells? .............. 'All of the animals, plants and microbes we use in our food system, our agricultural system, are genetically modified in one way or another,' says Bruce Chassy at the University of Illinois at Urbana-Champaign. 'That, or they're wild.' .............. More than four-fifths of the soybean, corn and cotton acreage in the United States last year used genetically engineered crops, according to a 2010 National Academies of Sciences study."
