| | 4 / 9 4. Your kitchen sink
It's hard to believe that the place where you prepare food and wash your dishes is actually germier than the bathroom, but a group of Arizona researchers beg to differ. Their study found that the moist environments in the kitchen -- the sink, sponge and faucet handle -- are the most contamined with bactera, and the toilet seat was the least contaminated.
Reduce the risk: Food, especially raw fruits and vegetables, potentially carry loads of pathogen like salmonella, campylobacter and E. coli, so clean your kitchen counter and sink after preparing food. Clean the sink twice a week by scrubbing the basin and pouring a mix of bleach and water down the drain. Wash your sponge in the dishwasher, or microwave it until steam appears (about 30 seconds). Watch carefully to avoid causing a fire.
