The 10 dirtiest items in your home

Objects in your home may not be as clean as they appear.

Germs that cause disease are found on many household items, according to research by NSF International, a global public health and safety organization. Scientists recently tested 30 surfaces in 22 homes to measure levels of yeast, mold, salmonella, E. coli and staph germs.

These 10 items were found to have the highest germ counts (ranked from least to most dirty):

10. Cutting boards
9. Stove knobs
8. Kitchen counters
7. Pet toys
6. Bathroom faucet handles
5. Coffee makers
4. Pet bowls
3. Toothbrush holders
2. Kitchen sinks
1. Dish sponges and dishcloths

Although most people think of bathrooms as the most germ-ridden spots in the house, findings indicated the kitchen is the biggest area of concern.

“The kitchen is a prime area for germs because of the many crevices that can hold water or splatters of food, and because of the use of cleaning sponges and cloths, which are breeding grounds for germs,” says Dr. Stephen Sokalski, an infectious disease specialist with Advocate Christ Medical Center in Oak Lawn, Ill. “It’s known that raw meat can cause food poisoning, but raw vegetables can also hold highly contagious germs such as E. coli and norovirus, so they must be washed well before eating.”

He also says it’s crucial for people handling food to wash their hands thoroughly before, during and after food preparation to avoid spreading disease.

According to the U.S. Centers for Disease Control and Prevention, gastrointestinal illness can be spread by contaminated food, and food-poisoning is less likely in kitchens that have been properly cleaned and sanitized.

“It’s still important to pay attention to the bathroom,” says Dr. Sokalski, “as bacterial and viral germs are sprayed with each flush of the toilet.”

Dr. Sokalski recommends these tips for keeping your home clean:

1. Use over-the-counter cleaning products for your kitchen and bathroom. Those that contain bleach are the most effective.
   • Wipe down sinks and drains each day.
   • Countertops, appliances and faucet handles should we wiped down two to three times a week.
   • Toilets, surprisingly, have been found to have lower bacteria counts. Clean these, as well as tubs and showers once a week.
2. Fecal coliform bacteria from raw meat are often found on cutting boards, sponges and dishcloths.
   • Use separate cutting boards for meat and vegetables to avoid transferring germs. Raw vegetables have also been associated with food poisoning, which often happens when they come in contact with surfaces that have been used for raw meat.
   • Wash cutting boards in the dishwasher after each use. Or, soak for five minutes in a sink full of water with a little bleach. Rinse to clean after.
   • Wash kitchen sponges and dishcloths in the washing machine, or soak in bleach water and rinse clean after each use.
3. Keep toothbrushes covered and away from the toilet. Storing in a cabinet is best.
4. Follow the cleaning instructions included with your coffee maker.
5. Thoroughly clean your pet’s food and water bowls to avoid germs, bugs and mold that can make them sick. Wash the bowls at least once a week in the dishwasher, or preferably, clean them after every meal with hot water and dish soap.
6. Soak hard and rubber pet toys in warm, soapy water and scrub with a sponge. Stuffed or plush pet toys can be cleaned in the dishwasher or washing machine.
