Some nasty germs have figured out a new way to keep in touch with you.

If you’re not washing your hands when you should, you might want to think twice about taking that next cell phone call.

In a new study from England, researchers took 390 samples from the hands and cell phones of volunteers. The people also reported how often they wash their hands. The researchers found E. coli bacteria on 16% of the hands they checked, as well as 16% of the cell phones.

However, 95% of the participants claimed they washed their hands with soap and water whenever possible.

E. coli bacteria lives in your digestive system and the germs can get on your hands after using the restroom. But keeping the bacteria off your cell phone isn’t hard. Be sure to wash your hands after using the restroom, changing a diaper or handling animal waste. To wash them well, get your hands wet, rub your hands together for at least 20 seconds with soap and then rinse under running water.

If soap and water aren’t available, an alcohol-based hand sanitizer can work in a pinch.
