Dish sponge: a hotbed of germs

The kitchen is one of the places where we must be more careful with hygiene, since, being the same place where we store our food, it can also be the place where more microbes are housed.

Did you know that dish sponges are the second largest microorganism host, only after drains? This is stated by a study carried out by the Institute of Precision Medicine at Furtwangen University and Justus Liebig University Giessen, in Germany.

The study states that the number of bacteria found in kitchen sponges corresponds to 7 times the number of inhabitants on Earth, the same as contained in feces!

These data were made based on an investigation that was carried out in 14 sponges with different techniques, in which bacteria such as bacteria were found both inside and outside. Enterobacter cloacae, Campylobacter, Salmonella, Staphylococcus, Moraxella osloensis Y Escherichia coli. All of these can cause serious infections, especially in people with a weak immune system.

What to do with used sponges?

According to the study, published by the journal Scientific Reports, no matter how much the sponges are cleaned with soap and water, or even if they are boiled, these bacteria do not disappear, on the contrary: they multiply more quickly.

Containing so many microbes, if we use these old sponges, all we do is spread these bacteria all over the kitchen. This is known as cross contamination, which increases the risk of infections and is considered a leading cause of foodborne illness outbreaks.
