A dish sponge is an essential element of every kitchen. Even if we use a dishwasher, we often resort to a sponge, which quickly becomes dirty. We often don't even realise how much residue remains on the sponge's surface.
Studies show that dish sponges are a massive source of germs. Dr Markus Egert and his team from the university in Furtwangen in the Black Forest thoroughly examined what is on a typically used sponge. The publication surprised many people.
The research results were shocking. On one sponge, as many as 82 billion bacteria and 362 different types of microbes were found, comparable to human faeces. As Dr Egert emphasised, there are few places on Earth like this. A sponge creates an ideal environment for microorganisms because it is moist, warm, and contains remnants of substances that bacteria feed on. This should give us pause.
How often to replace a dish sponge? Regularly and often
Most people change their sponges only when they notice significant wear. This is definitely too late - a dirty and soggy sponge means a massive accumulation of bacteria. Specialists recommend replacing the sponge every 2-3 days or at least once a week. It's a matter of hygiene and our safety.
If you frequently wash dishes by hand or have many household members, you should do this more frequently. Otherwise, you risk transferring bacteria from the sponge to other surfaces in the kitchen, which can result in them transferring to food, consequently causing health problems. Germs can lead to serious food poisoning and illnesses.
Some people try to disinfect the sponge. Unfortunately, washing in the dishwasher, scalding with boiling water, or even microwaving does not eliminate all microorganisms. It's only a temporary measure. The safest solution is simply to replace the sponge regularly.
An interesting aspect of maintaining cleanliness is silicone sponges. They do not accumulate bacteria and do not need to be replaced as often as traditional sponges. However, users note that they are somewhat less effective at removing dirt.
