The Dirty Truth About Kitchen Germs

By Elizabeth Brownfield for Life & Beauty Weekly




What would you guess is the germiest thing in your house? The trash can? The toilet? It’s actually -- gulp! -- the kitchen sink. In fact, the entire kitchen is a hotbed of bacteria, according to a study by the Hygiene Council, a group of global health experts. The room plays host to half of the top 10 germiest areas in your home, even though most people say they regularly clean the kitchen.

“The potential for bacteria is so high in the kitchen because you bring in uncooked meats and produce that can introduce E. coli, Salmonella and other bacteria,” says Dr. Charles Gerba, who holds a doctorate in microbiology and teaches at the University of Arizona. “Cooking kills the bacteria, but handling it increases the risk of spreading germs to other foods and surfaces, like the sink and countertop.”

Fortunately, getting rid of your kitchen germs is a snap. Here are the top five germ-prone areas -- plus quick tricks for cleaning them.

1. The Kitchen Sink

In most drains alone, there are half a million bacteria per square inch, says Gerba. “Everything gets tossed in the sink -- raw food, scraps, dirty dishes,” he says. “Plus, it’s constantly wet, which creates the perfect environment for bacteria to grow.”

Banish the bacteria: Simply spray your basin and drain with disinfectant every night after cleaning up the dinner dishes. No need to wipe!

2. Sponges

The thing you rely on to clean your kitchen may be sabotaging your efforts. “If you use a sponge to wipe a bacteria-containing area and then use it to wipe countertops and other surfaces, you give germs a free ride around your kitchen,” explains Gerba.

Banish the bacteria: Designate one sponge for washing dishes and another sponge or cloth for wiping surfaces. Toss sponges in the dishwasher with a regular load at least once a week (or whenever one touches raw food). Microwaving a sponge for two minutes also kills bacteria.

3. Cutting boards

Cutting boards are big germ hangouts. Why? “First, you use them to prep things like raw chicken,” says Mary Findley, author of The Complete Idiot’s Guide to Green Cleaning and owner of Mary Moppins cleaning products. “And second, knives create tiny grooves that trap bacteria and make them hard to clean.”

Banish the bacteria: To prevent cross-contamination, use one cutting board for meat, poultry and seafood, and another only for produce. Wash them after every use: Glass and plastic boards can go in the dishwasher, but wood cutting boards need to be washed and dried by hand. You can also apply mineral oil to wood boards every month or two, which helps seal crevices and block bacteria, says Findley.

4. The Faucet

After handling raw meat, most people reach for the faucet to wash their hands. But that leaves bacteria behind on the handle. What’s more, germy sponges and dishcloths are often stored nearby or draped over the faucet.

Banish the bacteria: When you spray the sink’s basin, also hit the faucet, the handle and the spigot. Or wipe all faucet surfaces with an antibacterial cloth, says Gerba. 

5. The Refrigerator

The fridge handle sees a lot of action, and all those hands can unknowingly spread pathogens. As for the inside, “the bottom shelf is the worst,” says Findley. “When foods leak or drip from above, they all collect there.”


Banish the bacteria: Wipe down the handle, drawers and bottom shelf before your weekly supermarket trip, suggests Findley. Once a month, take out and wash the drawers with soap and water, letting them dry thoroughly.
