<Picture> <Picture><Picture> By Ned Potter ABCNEWS.com V E R O ÿB E A C H, Fla., Nov. 19 - When a farmer plucks a grapefruit from the trees, it's frankly quite dirty-stained with bacteria, mold and pesticides. <Picture>ÿÿÿÿFor decades, American fruit packers have washed food in chlorine, but even that doesn't kill everything. Plus, it leaves a chemical residue behind. ÿÿÿÿ Now there's another way to clean fruit, vegetables and other foods that is 3,000 times more effective: ozone. Caged Lightening Mention ozone and most of us think of smog or that troubling hole in the stratosphere. ÿÿÿÿ But remember how fresh the air smells right after a thunderstorm? That's partly because as lightening cuts through the air it creates ozone-a very reactive form of oxygen that happens to be great at getting rid of dangerous pathogens like E. coli, salmonella, or cyclospora. ÿÿÿÿ "In water it's 3,000 times faster acting than chlorine, killing viruses and bacteria," says Charles Pearsall, who's company, Tri-O-Clean Systems, makes ozone generators for food companies. ÿÿÿÿ The generators pass oxygen through small chambers that are charged with high-voltage electricity in a process that turns the oxygen into ozone gas. The gas is then pumped into water, which is pressurized and sprayed over the fruit. ÿÿÿÿ Afterward, the dirt-ladden runoff is filtered clean and pumped back into the tanks to repeat the process. "We've been able to recycle 100 percent of our water usage," reports Morell Mahan of Quality Packers in Vero Beach, Fla. Tested and Approved One of its benefits of ozone is that it quickly turns back into regular oxygen and leaves no chemicals behind on the food. ÿÿÿÿ The U.S. Food and Drug Administration approved ozone for disinfecting food just this summer-but it's hardly new. ÿÿÿÿ In Japan and Europe, ozone has been used on food for decades. In Los Angeles, the city's water supply is cleaned with ozone, as is most bottled water. ÿÿÿÿ Food suppliers in this country, however, took little notice of ozone's disinfecting potential until the recent episodes of contamination began to frighten consumers and spark demands for tougher safeguards. ÿÿÿÿ As the technology spreads, it may mean a safer food supply and less anxiety among the public.
