We are all very concerned about the shelf life of food and whether the food in the refrigerator has deteriorated, but how do you know when to replace the various utensils in the kitchen? The kitchen utensils that are most prone to bacteria in the home may be kitchen dish towels, sponges for dishwashing and cutting boards. How often do types of kitchenware need to be replaced with new ones?
Some microorganisms can cause disease, and some microorganisms that are not originally disease-causing can cause disease when they arrive at the wrong place at the wrong time, but most microorganisms do not cause disease. We can protect ourselves from certain pathogens by maintaining good hygiene habits. As for the dishwashing sponges of the kitchen utensils we often use, the wetter the place, the more bacteria there will be. Therefore, the sponge for dishwashing in the kitchen utensils should be placed in a suitable place.
In an ideal situation, changing the sponge of high quality kitchen utensils every day is the healthiest. But the more realistic approach is: put it on the edge of the kitchen sink for washing only; use hot soapy water for washing dishes; disinfect it every day. The easiest way is to boil it in water and keep it boiling for at least 5 minutes; the dish-washing sponges of kitchen utensils should be replaced every week or every two weeks. In addition, it is recommended to make use of kitchen towel instead of sponges to wipe the counter, and never let the raw meat touch the dishcloth or sponge. The same goes for rags and dish towels in kitchen utensils. If you are cooking every day, you need to turn these items into clean items every day.
It can be replaced when it looks worn out. Whether you use wooden, plastic or stone cutting boards at home, you should "separate raw and cooked". Use at least one cutting board for kitchen utensils to cut raw meat, and another cutting board for vegetables and other items to avoid cross-contamination. After each meal, it should be cleaned with detergent/soap water to remove oil stains and kill bacteria. If your cutting boards at home have excessively worn or have deep grooves that are difficult to clean, you should throw them away.
