Despite the fact that the sole purpose of the refrigerator is to keep your food safe—by chilling it enough to slow bacterial growth and rotting— it can actually pose some hazards to your health. When you think about it, it makes sense: It’s one of the few places you go in and out of multiple times per day. And when you do, you’re typically moving around food, in the middle of cooking (hello, bacteria on your hands!), or putting away new packages (which have spent time in transit, picking up who-knows-what along the way).
While there are a few spots you would probably guess are germ-y—the door handles, for one—the grossest spot in your fridge is actually pretty surprising.
