Remote control
University of Virginia Health System researchers, studying the homes of adults with early cold symptoms, found six out of 10 remote controls tested positive
for rhinovirus. Traveler's alert: Remotes in hotel rooms are rarely cleaned, scientists say. That's enough to make you want to skip TV and grab a book.
Protect yourself: Wash hands regularly and use hand sanitizers. Clean the remote with a disinfecting wipe before you start surfing channels.
Salt and pepper shakers
The University of Virginia researchers in the same home study found an unusual location for rhinovirus - salt and pepper shakers. "A person gets mucus
on their fingers, then picks up the salt and pepper shakers, and they leave [the virus] there," says Dr. Owen Hendley. Other germ reservoirs: Refrigerator
and dishwasher handles.
Protect yourself: Wash hands frequently and clean objects with disinfecting wipes.
Purse
In a small study, Nelson Labs of Salt Lake City tested handbags for traces of bacteria. Among the lipstick, pens, and odds and ends, they found staph, E.
coli, salmonella and pseudomonas, which can cause eye infections. "They all had quite a bit of bacteria contamination," says Amy Karren of Nelson
Labs.
Protect yourself: Hang up your purse, and keep it off the kitchen counter. Wipe the bag with a mild soap or disinfectant.
Pets
Some dogs, cats and other animals have become infected with the dangerous methicillin-resistant Staphylococcus aureus. There's even evidence that MRSA
can jump between humans and pets.
In one test, Simmons College researchers swabbed random households of healthy people to find what pathogens were there. MRSA was found in about one-quarter of
the homes, and cat owners were more likely than others to have it. But before you put your pet up for adoption, note that scientists say pet MRSA infections
are rare, as is transmission of MRSA from humans to pets.
Protect yourself: Wash or sanitize your hands before and after playing with a pet.
Grocery cart
A recent University of Arizona study found that the handles of almost two-thirds of shopping carts were contaminated with E coli. Drool, saliva and mucus
from children also collect there. The grocery cart "is one of the most surprising places [for anal sex] we've come across," says Chuck Gerba, a
microbiologist who conducted the study.
Protect yourself: Swab the handle with a disinfectant wipe. Bag your fresh produce, and keep it off the seat where diaper-bottomed children have been sitting.
Showerhead
Researchers at the University of Colorado at Boulder studied 50 showerheads from nine cities and found about 30 percent harbored significant loads of
Mycobacterium avium, a pathogen linked to pulmonary disease. It most often affects people with compromised immune systems, but occasionally can infect healthy
people. The pathogens, clumped together on the inside of showerheads, can be inhaled into the lungs.
Protect yourself: Stick with baths? Not really. Showering is still safe for most people. Those with compromised immune systems should change showerheads
regularly, and use metal ones, not plastic, researchers say.
Desk
Office desks contain hundreds of times more bacteria per square inch than office toilet seats. "Desks in schools are much germier than office
desks," microbiologist Gerba says. "Women's desks are germier than men's," he adds, because women tend keep a lot more food and
cosmetics in and around their desks than men.
Protection: If you can't retire early, try wiping down the work areas with disinfectant wipes and washing hands frequently.
Cell phone
Cell phones are stowed in nice, warm pockets, making a good breeding laboratory. Your phone can carry lots of bacteria, including staph, which can cause
skin infections. "The flip phone is germiest because it keeps moisture in more," says Gerba, who is also known as "Dr. Germ."
Protect yourself: Use a disinfecting wipe regularly and think about where you lay your phone down. Wash your hands frequently. And be careful in borrowing
someone else's cell.
Carpet
Besides tracking in dirt, the soles of shoes can bring indoors traces of coliform, which includes fecal bacteria. Carpets also harbor tons of bacteria, dust and pesticide residue. "It's a living world right under your feet," Gerba says. His University of Arizona study found more than 200,000 particles of bacteria in one square inch of carpet.Protect yourself: Vacuum regularly with a strong vacuum cleaner. Even vacuum cleaners can have E. coli and salmonella growing inside them, Gerba says. Make sure you wash your hands after you handle a vacuum bag or receptable, he adds. You may want to consider leaving your shoes at the door before entering the home.
