Startling News About Your Underwear

Beware of your dirty underwear! Just touching it could make you sick.

When it comes to germs, dirty underwear is just about the worst thing you can touch, according to Dr. Germ, a.k.a. Charles Gerba, a microbiologist and clean water expert at the University of Arizona.

Here's the real shocker: Your clean underwear isn't much better. There is about a 10th of a gram of feces in the average pair of dirty underwear.

Thanks to our propensity to use cold water when we turn on the washing machine to save wear and tear on clothing and use short wash cycles to save on spiraling energy costs, our dirty laundry is not being properly sanitized, reports Reuters.

That means viruses such as hepatitis A, rotavirus and bacteria such as salmonella--all of which are carried through feces--survive not only the wash, but also an average 28-minute drying cycle.

You can kill all those nasty germs if you wash your clothing in hot water. "Water at 140 degrees Fahrenheit will sanitize laundry," Gerba told Reuters. But only 5 percent of Americans use hot water for laundry."

The bottom line? Don't wash the handkerchiefs and kitchen towels with your underwear. And wash your hands after you touch the dirty and clean laundry
