The sponge may not be the most hygienic way to clean dishes, but there is an alternative
Kitchen sponges contain more bacteria than brushes and are not the most hygienic way to clean your dishes, according to researchers in Norway.
"Salmonella and other bacteria grow and survive better on sponges than on brushes. "The reason for this is that sponges in everyday use never dry out," said Trond Møretrø, a research scientist at Nofima, a Norwegian food research institute.
While many bacteria are not harmful, those that are - like salmonella - can be spread by sponges on kitchen hands, kitchen surfaces and appliances and potentially make people sick.
