How often should I change the dish sponge? The deadline not to be exceeded

A study carried out by the University of Furtwangen, the Justus Liebig University of Giessen and the Helmholtz Center in Munich revealed the presence of as many as 362 different types of bacteria in kitchen sponges . Some bacterial density levels were comparable to those found in fecal samples, highlighting the need for regular sponge replacement.

Risks linked to bacteria present in dishwashing sponges
About 50 percent of bacterial species found in sponges belong to risk group 2, meaning they are potentially pathogenic.

People with weakened immune systems, such as young children, the elderly and people with chronic illnesses, are particularly vulnerable.

Although diarrhea pathogens and fecal bacteria are rarely detected, maintaining strict hygiene is essential to prevent any risk.

Can you clean dish sponges?
Wanting to clean dish sponges may seem tempting, but it’s not an effective solution. Neither the microwave nor the washing machine is recommended for cleaning sponges, as their structure is not heat resistant . Additionally, even if bacteria counts temporarily decrease after cleaning, pathogens can quickly proliferate again as they develop greater tolerance to stress.
