What is the designated temperature range for a freezer?

The designated temperature range for a freezer is typically recognized as being below 0 degrees Fahrenheit, with many guidelines recommending a standard of around -13 to 14 degrees Fahrenheit for optimal food preservation and safety. This range is crucial for maintaining the quality of frozen foods, preventing the growth of bacteria and slowing down enzyme activity that can lead to spoilage. Keeping temperatures consistently within this range ensures that ice cream remains solid and meats stay properly frozen, thereby extending their shelf life.

The other ranges provided do not meet the criteria for freezer temperatures. The second option falls within a refrigerator's temperature setting, which aims to keep items cool but not frozen. The third and fourth options describe significantly warmer temperatures, which are inappropriate for freezing as they can lead to thawing and spoilage of previously frozen items. Thus, the correct choice aligns with established guidelines for proper food storage in freezers.
