The toilet seat has acquired an unfair reputation as the dirtiest item in the average household. But scientists say there are far filthier places in our house, some of them where we least expect.
Would you chop your vegetables on your toilet seat?
His studies have found that on the average toilet seat there are 50 bacteria per square inch.
“It’s one of the cleanest things you’ll run across in terms of micro-organisms,” he says. “It’s our gold standard – there are not many things cleaner than a toilet seat when it comes to germs.”
But the filthiest culprit in our homes is the kitchen sponge or cloth.
According to Gerba, there are about 10 million bacteria per square inch on a sponge, and a million on a dishcloth.
In other words, a kitchen sponge is 200,000 times dirtier than a toilet seat, and a dishcloth is 20,000 times dirtier.
