食中毒の多い時期、台所のスポンジを清潔に保つ方法について。

Your kitchen sponge harbors zillions of microbes. Cleaning it could make things worse.


That sponge in your kitchen sink harbors zillions of microbes, including close relatives of the bacteria that cause pneumonia and meningitis, according to a new study. One of the microbes, Moraxella osloensis, can cause infections in people with a weak immune system and is also known for making laundry stink, possibly explaining your sponge’s funky odor.

Researchers made the discovery by sequencing the microbial DNA of 14 used kitchen sponges, they report this month in Scientific Reports. Surprisingly, boiling or microwaving the sponges didn’t kill off these microbes Indeed, sponges that had been regularly sanitized teemed with a higher percentage of bacteria related to pathogens than sponges that had never been cleaned. This could be because pathogen-related bacteria are more resistant to cleaning and rapidly recolonize the areas abandoned by their susceptible brethren—similar to what happens to our gut after an antibiotic treatment, the scientists say. When the researchers put the sponges under the microscope, they discovered that a single cubic centimeter could be packed with more than 5 x 10^10 bacteria, which corresponds to around seven times the number of people inhabiting the Earth. Such bacterial densities, the scientists say, are found only in feces. But don’t worry—the solution to a clean sponge is simple: Just replace it every week.

研究では、台所スポンジ1平方インチあたり1000万個の細菌が検出されたという報告がある。十分に消毒しなければ、細菌の量はトイレの便座より多いとされる。


台所スポンジには食品残渣がつきやすい、細菌はプラスチックも栄養にできる。濡れている台所スポンジは湿度が保たれ、暗所で室内という環境温度もあるので、細菌には繁殖条件が揃っている。


除菌方法
熱湯消毒で除菌

日光で除菌

漂白剤で除菌

除菌ができる洗剤を使って除菌
