The kitchen sponge

It is used for cleaning, so you might think it is clean. But it is precisely its use on the surfaces to be cleaned (table, worktop or dirty dishes) that makes it a real bacterial incubator. These are the last fonts, such as pieces of food scraps or traces of sauce, to grow, especially since the sponge is regularly wet (moisture also promotes the proliferation of germs).

A 2002 study by the Japanese chemical company Kao (1) found that the kitchen sponge had the second highest charge of coliforms (bacteria living in the intestines of warm-blooded animals). the whole house after the siphons.

A new study, published in 2017 in le Scientific reports (2), has shown that it is the use that gives the sponge its bacterial charge, the latter being almost nil when the sponge is new. After use, the presence of proteobacteria (E. coli and salmonella in particular) is 68%.

In view of this risk of intense proliferation, it is recommended to wash his sponge two to three times a week, preferably at 60 ° C. If these washes make it possible to eliminate the bacteria in parts, the maximum service life of a sponge should in principle not exceed two weeks.

At the remote control

You may have become accustomed to disinfecting your phone regularly, but you’d better apply the same routine to your remote control. Passing from hand to hand at any time of the day, it becomes a receptacle for germs and bacteria of all kinds.

It even goes beyond the toilet seat: in a 2012 study by the American Society of Microbiology (3), researchers found 290 potentially pathogenic microorganisms per square centimeter, 20 times more than W equipment. .-C. A rag with disinfectant is therefore a must!

The hidden side of your pillow

Whether you have a quiet or restless night, in any case these few hours spent in your bed are no rest for your pillow. Mites and germs live there overnight, despite the presence of a pillowcase, up to more than a third of the weight of the pillow, according to a study by the British Public Health Agency on St Bartholomew University Hospital facilities (London).

time even the study director hypothesized that pillows are potential carriers of care-associated infections, such as Staphylococcus aureus.

To do this, changing the case is not enough. A 60 ° C washing machine tour is required every three months for synthetic pillows, when down pillows must be pressed. The latter still offer superior protection thanks to their tighter weave to hold the feathers.

On a daily basis, it is recommended to ventilate the room, as mites dry out when exposed to sunlight.

The toothbrush

After a scaling at the dentist, he may be advised by the toothbrush changer to avoid further contamination. Yes, a recent study from the University of Manchester (4) found that the toothbrush is home to no less than ten million bacteria, more than the glasses or the toilet floor.

The doormat

There are those who rush to take off their shoes as soon as they walk through the door of their home and there are those who are quite comfortable and can keep them on their feet even at home. Except that the soles of your shoes have piled up over the street in the street name of bacteria of all kinds including fecal bacteria, underline an article published on March 16 last on Conversation. To avoid the presence, even microscopic, of manure on the floor of your interior, it would be better to remove your shoes as soon as possible.

And if a passage on the doormat allows to remove, a good part of the bacteria present on the soles of your shoes by friction, it can force produces the opposite effect since it becomes over the uses the receptacle of amount of bacteria. Just like the sponge, it should also benefit from good regular cleaning.

Living room, kitchen, bathroom and the same lighting … bacteria and germs are actually ubiquitous in our daily lives. If the items described above need to be carefully maintained, it is never possible to get rid of all the dirt and so much the better! Exposure to bacteria allows the development of an effective immune system and reduces the risk of allergies.
