Final answer:
The optimal range for short-term refrigerated storage is 34-40 degrees Fahrenheit, which inhibits microbial growth and ensures food safety.
Step-by-step explanation:
The best temperature range for short-term refrigerated storage is option 2) 34-40 degrees Fahrenheit. Refrigerators in home kitchens or laboratories are usually set to maintain temperatures between 0 °C (32 °F) and 7 °C (45 °F) to inhibit microbial metabolism and slow the growth of microorganisms, which helps preserve refrigerated products like food or medical supplies. The ideal temperature to ensure food safety and prevent bacterial growth in refrigerated foods is at or below 4 °C (40 °F). Failure to maintain proper refrigeration can lead to rapid microbial growth, especially in the zone between 4 °C (40 °F) and 60 °C (140 °F), increasing the likelihood of foodborne diseases. For most refrigerated foods, temperatures above this range should be avoided to ensure short-term temperature stability and maintain post-preparative stability.
