Study reveals: dishwashing sponges are germ-spinners - this is how often you should replace the utensil. A total of 54 billion bacteria per cubic centimeter live on the kitchen utensils.
About half of them belong to the so-called risk group 2. There are also extremely high levels of bacteria on bed linen. The study was carried out by a team of researchers from Furtwangen University. It was published in the journal “Archives of Microbiology”.
