The dishwashing spongeAfter many uses, it begins to deteriorate at first glance, taking on a color similar to that of food fat and even losing its elasticity. Even so, there are those who are capable of continuing to use it, over and over again, without analyzing how many bacteria it could have accumulated.
But after looking at this, you’ll never do it again: Various studies have shown that that kitchen sponge becomes a true source of bacteriaeven more than other surfaces that are already considered dirty, such as the sink itself.
Research conducted by the University of Arizona revealed that can accumulate up to 10 million bacteria per square inch. This means that can be up to 200,000 times dirtier than a toilet seat.
The problem is not only the quantity, but the type of microorganisms that can lodge on its surface. Among them are potentially dangerous bacteria that, when coming into contact with plates, glasses and cutlery, can be transferred directly to food.

Why is the dishwashing sponge a source of bacteria?
Sponges meet the ideal conditions for the proliferation of microorganisms: constant humidity, food remains and room temperature. This environment encourages bacterial growth within hours.
Besides, Many people make the mistake of leaving them in the sink or soaking, which aggravates the problem.. Even if they are rinsed with soap or perfumed with disinfectants, bacteria can remain inside.
Continued use of a contaminated sponge can cause so-called cross contamination. This happens when germs move from the sponge to the kitchen utensils and then to the food.
Possible effects include gastrointestinal infections, stomach upset, and food poisoning.. Although a healthy person may not have serious symptoms, the risk increases in children, older adults, or people with weakened immune systems.
How often should you change it?
It is not necessary to throw away the sponge after each use, but it is important to renew it frequently. Specialists recommend changing it at least once a week or every two weeks at most, depending on use..
It is also traditional to let it dry completely after each wash and prevent it from remaining in stagnant water.
Likewise, experts consider a more hygienic option stainless steel or aluminum scouring padsknown as “lullabies”. These materials They retain less moisture and hinder the proliferation of bacteria.
