More germs in the vegetable drawer than in the toilet
In the home, especially in the bathroom and kitchen, we have to deal with mold and yeast, E. coli bacteria and salmonella, among other things. These can be found in the refrigerator and around the sink. A South Korean study has found that there are more different germs in the vegetable drawer than on the toilet seat. The biggest source of germs is the dishwashing sponge. Microbiological studies show that up to 54 billion bacteria can make themselves comfortable there – per cubic centimeter. That sounds threatening, but healthy people don’t immediately get sick from it.
Disinfect yes or no?
If you are healthy, you don’t need to worry about germs. The immune system usually copes well with them. Normal cleaning products are therefore sufficient. Disinfectants are only useful if stomach and intestinal viruses are on the move.
Cleaning-intensive zone: the kitchen
While the cleaning schedule in the living room or bedroom can be based on your personal tolerance for dirt, you should clean the kitchen regularly for hygiene reasons. Mold or even salmonella from chicken can be a health hazard. This is where food is prepared. In practice, this means cleaning work surfaces thoroughly, ideally every day or at least after cooking. The refrigerator also needs to be cleaned regularly, as germs feel particularly at home here.
Cleaning products, which ones do we really need?
Although there are hundreds of cleaning products, you can get by with just a few. Neutral all-purpose cleaners, mild scouring powder and vinegar cleaners are sufficient. They should contain as few fragrances and additives as possible. This protects the environment and is better for your health. Fragrances in particular can trigger allergies and irritate the respiratory tract. This is why spray bottles should also be used with caution. The fine mist can allow many ingredients to enter our respiratory tract, the (health-endangering) effects of which have not yet been researched.
