Kitchen sponges can become a receptacle for bacteria due to the warm and humid environment and food residues: how to sanitize them to reduce the bacterial load
The kitchen sponges they are indispensable tools in daily cleaning, but often become a real receptacle of bacteria. Due to the environment wet and warmand the presence of food residuescan host potentially harmful to health microorganisms.
A study conducted in Germany He revealed that only one cubic centimeter of a used sponge can contain one bacterial density comparable to that of the feces. Among the bacteria detected, the Moraxella Osloensisknown for his bad smell and for the risk of infections in subjects with a weak immune system.
Many people think that the simple washing with soap and water is sufficient to sanitize the sponge, but the study has shown that this method not only, but it can even Promote growth of the more resistant ones. Also techniques such as boil the sponge or put it in the microwave They did not prove effective in the long run.
How to correctly sanitize the sponge
According to experts, one of the most effective methods to reduce the bacterial load is the use of a Consultation solution. The microbiologist Philip Tierno, of the University of New York, recommends mixing Nine parts of water with a part of bleachimmerse the sponge for 10-30 seconds And then squeeze it well before letting her dry. This process helps eliminate germs and prevent bad smells.
If immersing the sponge in a disinfectant solution after each use seems complicated, the simplest solution is replace it frequently. Scientists suggest changing it at least once a weekavoiding to reuse old sponges that have already accumulated bacteria.
Another sign that indicates the need to change it is theunpleasant smell: a sponge that emanates a bad smell is certainly full of germs and potentially harmful to health. Using it to wash the dishes may mean spread bacteria On the whole service of dishes, instead of eliminating them.
