Before diving into this article, perhaps it’s best to set aside that morning bagel. While it’s common knowledge that germs are ubiquitous, the places they predominantly inhabit might surprise you.

Health.com published a list titled “The Dirty Dozen: The 12 Germiest Places in America.” From this list, we’ve identified the top three spots you’re most likely to come across during a workday and provided tips on keeping those pesky bacteria at bay.

The Kitchen Sink

It’s unsettling to think about, but if your workplace has a kitchen sink, you’d be wise to approach it with soap and hot water in hand. Kitchen sinks can harbor up to 500,000 bacteria per square inch in the drain alone. Shockingly, many experts claim that a kitchen sink can be more unsanitary than most restrooms. Although commercial cleaners are effective, sinks can still become contaminated during the day. If possible, wipe the sink down using hot water and soap. Regardless, ensure you wash your hands both before and after using the sink, especially before handling any food.
