Between making ready and dealing with meals, piling soiled dishes within the sink and continually wiping up spills and crumbs, you may see how your kitchen is a major spot for germs. But the germiest merchandise in your kitchen could shock you, as a result of it’s what you employ to maintain it clear.
“A dirty sponge can actually contain more bacteria than a toilet seat,” mentioned Darin Detwiler, a meals security professional and professor at Northeastern College. “Each use spreads germs instead of removing them, turning your efforts to clean into an unintentional act of contamination.”
As a result of they’re “warm, damp and full of food particles,” they’re “ideal conditions” to gasoline bacterial development, he added.
We talked to consultants concerning the dangers of utilizing a grimy sponge, methods to correctly clear it, and when to exchange it — plus just a few different surprising kitchen gadgets the place you could discover micro organism lurking.
So, why do sponges harbor a lot micro organism?
A sponge is “used often, wet most of the time, and doesn’t get properly cleaned,” mentioned Becky Rapinchuk, cleansing professional and founding father of Clear Mama.
Moreover, as a result of sponges are porous, they “have an incredible amount of surface area,” defined Jason Tetro, a microbiologist and creator of “The Germ Code.” “Bacteria can coat the entire surface and even grow three-dimensionally.”
The quantity of micro organism can double in as little as 30 to 60 minutes in some instances, he mentioned. In this examine, “tens of billions [of bacteria] were found for every cubic centimeter.”
Fecal micro organism can be usually present in soiled kitchen sponges, added Charles Gerba, a microbiologist and professor on the College of Arizona. For instance, fecal micro organism can switch to the sponge whenever you wipe up surfaces the place uncooked meat was positioned or deal with uncooked meat after which contact the sponge.
One other method fecal micro organism may find yourself on the kitchen sponge is should you’re not washing your palms correctly, Tetro mentioned. (Correct hand-washing contains wetting your palms with water, lathering with cleaning soap, scrubbing for no less than 20 seconds, rinsing and drying, in accordance with the Facilities for Illness Management and Prevention.)
What occurs should you use a grimy sponge?
Whereas a number of the micro organism in the environment is innocent, “there is always the chance for more troubling bacteria, especially from raw meat juices,” Tetro mentioned. When you’re uncovered to a excessive sufficient variety of these pathogens, you’re in danger for getting sick.

Detwiler listed salmonella, E. coli, campylobacter and listeria as a number of the micro organism more likely to dwell in sponges, noting they “can lead to severe gastrointestinal distress, dehydration and even life-threatening complications, particularly in young children, older adults and those with weakened immune systems.”
The opposite threat with sponges is that they don’t simply comprise micro organism, however can unfold it round your kitchen.
“Each time you wipe a countertop or rinse a dish, you risk transferring millions of harmful microbes to your hands, cooking tools and food,” he mentioned.
How usually do you have to clear and change your sponge?
There are just a few totally different strategies our consultants advised, however all of them agree: It’s key to remain on prime of cleansing, disinfecting and changing your kitchen sponge.
“I recommend putting it in the top rack of your dishwasher nightly,” Rapinchuk mentioned. “Wring it out in the morning and let it air-dry.”
Another choice is to make an answer of 1 quart water and three tablespoons chlorine bleach, and soak the sponge for 5 minutes, advised Kristin DiNicolantonio, a senior director on the American Cleansing Institute. Rinse the sponge with water, and let it air-dry. (Don’t overlook to scrub your palms after.)
When it comes to how usually to exchange your kitchen sponge, DiNicolantonio recommends each two to 3 weeks (relying on how usually you employ it) or on the first signal of odor or harm.
“An even safer alternative is to use brushes, which can be thrown in the dishwasher, or washable dishcloths, which dry faster and can be disinfected in the laundry,” Detwiler added. (A examine confirmed that dishwashing brushes have decrease quantities of micro organism than kitchen sponges.)
Don’t overlook about these different often-overlooked germy kitchen gadgets.
Whereas the kitchen sponge accommodates essentially the most micro organism (by far), we requested our consultants about just a few different gadgets within the kitchen that harbor micro organism and aren’t usually cleaned sufficient.
Fridge
“If there’s a small spill somewhere [in the fridge], the bacteria will start growing and spreading to other items,” mentioned Kadi Dulude, proprietor of Wizard of Houses NYC. “I’d recommend cleaning up spills immediately when they happen and then … [wiping down] all possible surfaces before each grocery trip when the fridge is somewhat empty.”
She advises utilizing a vinegar-water combine to wash the fridge as a result of it additionally helps do away with smells. Lastly, utilizing fridge liners (non-slip and washable) could make it simpler to maintain the cabinets and drawers clear.
Chopping Board And Counter tops
“Cutting boards come in contact with raw meats, and when these juices are left to sit on surfaces, they’ll start growing bacteria,” Dulude mentioned. “Do not leave in the sink. … You should wash and thoroughly scrub the cutting board right after using it.”
She suggests utilizing pure wooden boards as an alternative of plastic as a result of it’s been “proven that wood has natural antibacterial properties to inhibit bacterial growth.” Additionally make certain to make use of totally different reducing boards for greens and meats, she added.
Counter tops carry the identical threat for micro organism after uncooked meats and greens have been sitting on them. Tetro advises utilizing soapy water to wash after each use, and if uncooked meat has been on the floor, use a “disinfectant that is safe for food-contact surfaces.” Rinse effectively after.
Kitchen Sink
From washing pots and pans to rinsing produce, your sink is used for a lot of issues and plenty of micro organism might be lingering in there, in accordance with the U.S. Division of Agriculture.
“Also people often open wrapped meat products over the sink to avoid getting juice from the product on the countertop,” which may result in extra micro organism, Gerba defined.
He mentioned it’s finest to disinfect the sink with a bleach wipe or kitchen disinfectant, particularly after making ready uncooked meat merchandise. Moreover, NSF recommends disinfecting the sink a few times per week and kitchen drains and disposals as soon as a month by pouring a bleach water resolution down the drain (1 tablespoon family bleach and 1 quart of water).
One final thing to recollect.
Meals security “starts in our own kitchens,” Detwiler mentioned. “The choices we make (whether it’s replacing a sponge … or properly washing our hands) could be the difference between a safe meal and a preventable illness.”
