5 Worst Germ Hot Spots
Germs (the catchall name for bacteria, viruses, and other microorganisms) are everywhere—at home, in the office, even in your car. Luckily, about 99% of them can't harm us. But the other 1% can be annoying, uncomfortable, or downright scary: Most of these pathogens are either viral or bacterial and can cause everything from a common cold to a potentially life-threatening infection.
You may think you know the obvious places that germs propagate—the doctor's office, the soles of your shoes—but many more germ-friendly locales are completely unexpected yet no less dangerous. We uncovered a host of surprising new spots where germs like to lurk, and offer easy solutions to keep you and your family safe and healthy.
1. Waste disposal unit
Bacteria from last night's dinner could end up on today's food and utensils if you're not careful. That raw chicken or spinach you're rinsing for dinner is often loaded with harmful bacteria, which can make the young, the elderly, or anyone with a compromised immune system seriously ill. In fact, there are often more than 500,000 bacteria in the kitchen sink—about 1,000 times more than the average toilet has. Although the metal part of the disposal produces ions that can help kill germs, they still love to grow on the crevices in and around the slimy rubber stopper. That means your disposal can become party central for bacteria, contaminating whatever touches it—dishes, utensils, even your hands.
Keep it clean: At least once a week, clean the disposal's rubber stopper with a diluted bleach solution—soap and water aren't enough.
2. Welcome mat
It serves to greet not only your guests but also all the bugs on the bottoms of their shoes. In fact, one study found that nearly 96% of shoe soles had traces of coliform, which includes f***l bacteria. "The area near your front door is one of the dirtiest in the house," says Reynolds. Once bacteria plant their stakes in your mat, anytime you walk on it, you give them a free ride into your home.
Keep it clean: Spray the doormat once a week with a fabric-safe disinfectant (such as Lysol Disinfectant Spray). Leave shoes at the door, and avoid resting bags and groceries on the mat, too.
3. Vacuum cleaner
It's all in the bag—including spreadable germs. "Vacuums—including the brushes and bags—are like meals-on-wheels for bacteria," says Charles Gerba, PhD, professor of environmental biology at the University of Arizona. "You suck in all this bacteria and food, creating an atmosphere for growth." A recent study by Gerba and his team found that 13% of all vacuum cleaner brushes tested positive for E. coli, which means you could spread it around the house each time you use the appliance.
Keep it clean: Change your vacuum bag frequently, and do so outdoors to avoid the cloud of bacteria that filters into the air. (Vacuum bags that feature antibacterial linings are best, and are available for many major brands.) Clean the cavity of a bagless vacuum with diluted bleach and let it air-dry.
4. Car dashboard
This is your vehicle's second-most-common spot for bacteria and mold. When air—which carries mold spores and bacteria—gets sucked in through the vents, it's often drawn to the dashboard, where it can deposit the spores and germs. Because the dashboard receives the most sun and tends to stay warm, it's prime for growth. (The number one germ zone? Food spills.)
Keep it clean: Regularly swipe the inside of your car with disinfecting wipes. Be more vigilant during allergy season—about 20 million Americans are affected by asthma, which is caused in part by an allergic reaction to mold.
5.Mobile phone
Drop your mobile any place that's convenient? Read this first. Several studies on cell phones and PDAs found that they carry tons of bacteria, including staph (which can cause skin infections), pseudomonas (eye infections), and salmonella (stomach ailments). Many electronic devices are sheathed in leather or vinyl cases, which provide plenty of creases and crevices for germs to hide.
Keep it clean: Use a disinfecting wipe a few times a week, and be conscious of where you rest personal items.
