Dish sponges are an essential cleaning item in any kitchen; their high absorbency and natural loofah bath sponge porous structure successfully remove stains, but they also serve as a breeding ground for germs, so they should be replaced on a regular basis.
Although sponges are consumable, careful housewives will not waste them; instead, they will regularly disinfect and hemp dish scrubber recycle them, wash them thoroughly with detergent, place them in boiling water, sterilize them in the microwave oven, and so on, which saves money and is environmentally friendly.
However, according to the study’s findings, the impact of sterilization is not very good, and cellulose sponge block just replacing the old one is more stable.
This German research examined 14 kitchen sponges to determine the types and quantities of bacteria present. The researchers initially examined the sponges under a microscope and discovered that the bacterium density is astonishingly high, with 50 billion germs per cubic centimeter, a level observed only in one other area – the faeces.
The researchers also used gene sequencing experiments to examine the DNA of more than 300 different species of bacteria found in sponges. While the majority of the bacteria were innocuous, half of the top ten were disease-causing, including those that cause pneumonia and meningitis, and may possibly infect persons with compromised immune systems.
Why is sterilization ruled out?
Because disinfection is pointless. According to studies, sponges contain the same quantity of germs even if they are not sanitized on a regular basis, and even boiling water or microwave ovens cannot entirely eradicate them. The most serious issue is that sterilized sponges contain more dangerous germs than unsterile sponges. Because hazardous bacteria have a stronger resistance and a faster reproduction rate, sterilizing sponges is required to eliminate innocuous bacteria and provide room for the growth of bad germs.
As a result, it is preferable to change the cleaning sponge on a regular basis; researchers recommend changing it once a week!
