Research has consistently shown that kitchen sponges are breeding grounds for bacteria. A study by the American Society for Microbiology found that pathogens like E. coli, Salmonella, and Staphylococcus aureus can survive on sponges for up to 16 days. Another study revealed that sponges can harbor more bacteria than a toilet seat, with up to 54 billion bacteria per cubic centimeter. The sponge's porous structure provides an ideal environment for microbial diversity, making it more conducive to bacterial growth than even laboratory petri dishes. ​

What's Happening Now

In light of these findings, health experts are emphasizing the importance of proper sponge maintenance. Regular replacement and effective cleaning methods are being recommended to mitigate the risks associated with bacterial contamination.​
