Hot dishes can be placed directly inside the refrigerator. If hot dishes are left to cool before being placed in the refrigerator, it often gives time for bacteria to grow. Generally speaking, when the food drops below 60 degrees Celsius, there are bacteria that start to grow, and when the temperature drops between 30 degrees Celsius and 40 degrees Celsius, the bacteria will multiply like crazy. Only when it drops below 7°C will the bacteria go dormant. Normal meals are usually put into the freezer of a refrigerator. Its temperature is usually around 5 ℃, which naturally inhibits bacterial growth well.
