According to a recent British survey, over 90% of currently used dish sponges in households contain a large concentration of bacteria. If taken that these bacteria pose a serious health threat, this is really alarming!
British experts from the Global Hygiene Council found that more than 85% of people don’t wash their dish sponge at a temperature high enough to kill the bacteria that thrives in them. As found in their research, sponges commonly used for dish washing contain six times more bacteria than bathroom doorknobs, which are considered a major source of disease and infection.
Sponges make the perfect environment for bacterial growth because they are constantly wet, which is extremely favorable for bacteria proliferation.
