Drawbacks of Desk Dining: Unhealthy Lunches and Weight Gain continued...
"If you get called away from your desk, and then you have to put off eating for an hour or two, and then you pick at your lunch over the day, you need to be concerned about the temperature of your food and food safety," says Moores.
In other words, your room-temperature chicken salad sandwich that's been sitting out for three hours can easily become a bacteria feeding ground. But wait, it gets worse. (You might want to put that sandwich down now.)
"The desk, in terms of bacteria, is 400 times more dirty than your toilet," says Charles Gerba, PhD, a professor of environmental microbiology at the University of Arizona in Tucson. "People turn their desks into bacteria cafeterias because they eat at them, but they never clean them. The phone is the dirtiest, the desktop is next, and the mouse and the computer follow."
To give your desktop the dirt test, Gerba says, "Turn your keyboard over and see how many crumbs fall out. The more of a snowstorm, the dirtier your desk."
