Health experts say kitchen dishwashing sponges should be replaced daily to prevent dangerous microbes. A study by scientists shows that sponges can harbor bacteria even after thorough cleaning. This could lead to issues like food poisoning and gastroenteritis.
According to experts, kitchen dishwashing sponges are a major source of dangerous microbes. A study conducted by scientists, led by Dr. Primrose Freestone, an expert in health-related dangerous microbes, examined sponges used for periods ranging from one day to five months. These sponges were repeatedly cleaned with disinfectants, yet results revealed several bacteria remaining after just 14 hours, even after washing with antibacterial soap and hot water.
A sponge used for three days was found teeming with bacteria, while those used for two to three months showed a swarming presence of microbes. Experts note that any type of dangerous kitchen microbe, including those causing food poisoning, gastroenteritis, and antibiotic-resistant bugs, will end up on the sponge. "Sponges aren't expensive and my advice is to change them daily," said Dr. Freestone.
If a sponge is used to wash dirty vegetables or raw meat, it is recommended to discard it immediately after use. Some people have turned to using brushes instead, which scientists say are cleaner, but brushes can also accumulate dangerous microbes over time. This advice underscores the importance of home hygiene to ensure better family health.
