Refrigerator food cold temperatures common to 4 ℃ 8 ℃, in this environment, the vast majority of the bacteria growth rate will slow down. But some bacteria are psychrophilic, such as Yersinia, Listeria monocytogenes in such temperatures but can reproduce rapidly, if the consumption of food infected with these bacteria, it can cause intestinal disease. The refrigerator freezer, the temperature is generally around 18 ℃ below zero, in which temperature, most bacteria will be inhibited or killed, so it has better inside storage of food preservation role. But the freeze does not mean completely sterilization, freezing ability is still some bacteria will survive.
