Kitchen sponge
“Contrary to public perception, the germiest place in your house is in the kitchen, not your bathroom,” says Adam Splaver, MD, a cardiologist based in South Florida. “You’re going to love the irony.
It’s your sponge — the one you use to clean your kitchen.”
In fact, a study by the Public Health and Safety Organization found coliform bacteria (which could indicate fecal contamination) on more than 75% of kitchen dish sponges, compared to only 9% of bathroom handles.
