10. To avoid foodstuff spoilage, articles should be stored in low temperatures, because
only a very small number of microorganisms can grow without air circulation.
11. If the temperature inside the refrigerator is above 4 °C (especially for prolonged
periods), harmful microorganisms are given advantageous conditions for growth.
For this reason it is necessary to keep the temperature of the refrigerator below 4 °C.
12. If the temperature of the freezer is -17 °C or below, this is the proper temperature for
storage of foodstuffs; however, freezing will not kill microorganisms but slow their
growth.

are extended by a factor of three to four with each drop in temperature of 10 °C.
