Common food preservation refrigerator refrigeration temperature of 4 to 8 ℃, in this environment, the majority of bacterial growth will slow. But some bacteria was addicted to cold, such as Yersinia, Listeria monocytogenes at this temperature but can rapidly multiply, if eating food infected with these bacteria, can cause intestinal illness. Refrigerator and freezer box, the temperature is generally around minus 18 ℃, at this temperature, most bacteria will be inhibited or killed, so it has better food stored inside Preservation.
