8 Germiest Public Places
Surfaces to avoid when you leave home.
June 20, 2013— -- intro: Prepare to be grossed out.
An average adult can touch as many as 30 objects within a minute, including germ-harboring, high-traffic surfaces such as light switches, doorknobs, phone receivers, and remote controls. At home, you do all that you can to keep the germs at bay. But what happens when you step out the door to go to dinner, do some grocery shopping, or visit the doctor's office? It's not pretty.
Here's where germs are most likely to lurk—and how you can limit your exposure.

A study in the Journal of Medical Virology reported that cold and flu viruses can survive for 18 hours on hard surfaces. If it's a popular restaurant, hundreds of people could be handling the menus—and passing their germs on to you.
Never let a menu touch your plate or silverware, and wash your hands after you place your order.

When the researchers ordered drinks at 21 different restaurants, they found 25 different microorganisms lingering on the 76 lemons that they secured, including E. coli and other fecal bacteria.
Tell your server that you'd prefer your beverage sans fruit. Why risk it? (You might want to skip the diet soda while you're at it; learn about seven gross side effects of diet soda.)
quicklist: 3category: Germiest Public Placestitle: Condiment Dispensersurl:text: It's the rare eatery that regularly bleaches its condiment containers. And the reality is that many people don't wash their hands before eating, says Kelly Reynolds, PhD. So while you may be diligent, the guy who poured the ketchup before you may not have been, which means his germs are now on your fries.
Squirt hand sanitizer on the outside of the condiment bottle or use a disinfectant wipe before you grab it. Holding the bottle with a napkin won't help; napkins are porous, so microorganisms can pass right through, Reynolds says.

Palm a spare paper towel after you wash up and use it to grasp the handle. Yes, other patrons may think you're a germ-phobe—but you'll never see them again, and you're the one who won't get sick.
quicklist: 5category: Germiest Public Placestitle: Soap Dispensersurl:text: About 25 percent of public restroom dispensers are contaminated with fecal bacteria. Soap that harbors bacteria may seem ironic, but that's exactly what a recent study found.
"Most of these containers are never cleaned, so bacteria grow as the soap scum builds up," says Charles Gerba, PhD. "And the bottoms are touched by dirty hands, so there's a continuous culture feeding millions of bacteria."
Be sure to scrub hands thoroughly with plenty of hot water for 15 to 20 seconds—and if you happen to have an alcohol-based hand sanitizer, use that, too. (Prefer a more natural route? Check out this DIY natural, effective hand sanitizer.)
quicklist: 6category: Germiest Public Placestitle: Grocery Cartsurl:text: The handles of almost two-thirds of the shopping carts tested in a 2007 study at the University of Arizona were contaminated with fecal bacteria. In fact, the bacterial counts of the carts exceeded those of the average public restroom.
Swab the handle with a disinfectant wipe before grabbing hold (stores are starting to provide them, so look around for a dispenser). And while you're wheeling around the supermarket, skip the free food samples, which are nothing more than communal hand-to-germ-to-mouth zones.

It's not surprising, then, that you're 100 times more likely to catch a cold when you're airborne, according to a recent study in the Journal of Environmental Health Research.
To protect yourself, try taking green tea supplements. In a 2007 study from the University of Florida, people who took a 450-milligram green tea supplement twice a day for 3 months had one-third fewer days of cold symptoms.

1. Take your own books and magazines (and kid's toys, if you have your children or grandchildren with you).
2. Pack your own tissues and hand sanitizers, which should be at least 60% alcohol content.
3. In the waiting room, leave at least two chairs between you and the other patients to reduce your chances of picking up their bugs. Germ droplets from coughing and sneezing can travel about 3 feet before falling to the floor.
