10 Sneaky Spots Germs Are Hiding

We come in contact with millions of germs every day (gross, we know). While most are harmless, some bacteria such as E.coli and Salmonella can cause serious infections. The good news? Hand washing, sanitizing lotions and disinfecting communal areas can reduce the chances of infection by 50 percent, according to Charles Gerba, a microbiologist at the University of Arizona, who has been studying germs in our everyday lives for more than three decades.

Check out our tips on how to protect yourself against germs in unexpected places.


Germs thrive in moist environments such as your toothbrush, notes Gerba. Add that to the fact that research in the 1970s discovered toilets spew fecal bacteria into the air every time they are flushed, so chances are, your toothbrush is teeming with microbes. To protect your mouth, replace your toothbrush every three to four months and close the toilet lid when flushing. If you want to be extra safe, the Philips Sonicare FlexCare electric toothbrush has a UV sanitizer that kills germs.

However, silver is antimicrobial, so smooth jewelry made from this metal should stay relatively germ-free.

In some cases, desktops have been found to have higher levels of bacteria than toilet seats. Workers spend hours a day touching, eating and heck, even sneezing on them. Custodians don’t clean them as they sweep through the office because they are considered private areas, so take up the charge yourself by regularly cleaning your desk with an antibacterial wipe.

When they aren’t on our shoulders, most purses are resting on the floors of restaurants, restrooms, movie theaters, cars, buses and sidewalks. A joint ABC News and University of Arizona investigation of 50 women’s handbags found that the outside bottom of the purses were teeming with bacteria, including fecal germs and those that can cause skin infections. The researchers found 6.7 million bacteria on one purse alone. Remember to wipe purses down from time to time with antibacterial cloths.

Not only can these bags contain bits of food from your shopping trip, more than half of people use these bags to haul more than just groceries—namely, things like shoes, dirty laundry and sweaty gym clothes. But only about three percent of people wash their reusable bags. “In some cases, we’ve found more E. coli in these bags than in people’s underpants,” says Gerba.
