Do you really know how to use the fridge in your home?

You know, the refrigerator will also potential food safety problems, accidentally bring "refrigerator disease." Because the refrigerator itself does not have the sterilization function, can only delay the process of food spoilage, not to mention some of the refrigerator does not defrost in time, hindering the flow of cold air, so that the refrigerator temperature to rise. If you mix raw and cooked, can cause cross-contamination of food; combined storage of too much food, too crowded, so the food surface temperature is low, the inner temperature is high, bacteria will "revive." Frequent opening and closing the refrigerator door, the box temperature suddenly changes, as the bacteria multiply and create a suitable environment. Many families are not careful cleaning, disinfecting refrigerators, provided the conditions are more bacteria. So, a refrigerator is not a "sterile container", not "safe", but should not become "trash."
Common cold refrigerator temperature of food 4 ℃ ~ 8 ℃, in this environment, the vast majority of bacterial growth rate will slow down. However, "psychrophilic bacteria" can be 0 ℃ ~ 20 ℃ environment of growth. That is, they continue in the refrigerator freezer growth and reproduction, contamination of food, such as Yersinia, Listeria monocytogenes in the temperature, but the rapid growth of this breed. Eating the contaminated food by these bacteria, the light were abdominal pain, diarrhea, fever, severe and even lead to sepsis. In addition, some fungi and mold can also cause cross-contamination of food in the refrigerator and spoilage.
Freezer temperature is generally around 18 ℃ below zero, in which temperature, most bacteria can be inhibited or killed on the store, including better preservation of food. But the freeze does not mean complete sterilization, there is still freezing ability of bacteria to survive.
