What is the ideal refrigerator temperature to maintain food safety?

The ideal refrigerator temperature is typically recognized as being between 34°F to 40°F. This range helps slow down the growth of bacteria, ensuring that perishable food items remain safe to consume for a longer period. Keeping the temperature at or below 40°F significantly reduces the risk of foodborne illnesses since most harmful bacteria thrive at temperatures above this range.

This temperature range is practical for daily use, as it allows foods to be chilled enough to stay fresh without freezing them, which can affect texture and quality. Additionally, setting the temperature below 34°F may lead to freezing of some items, impacting their taste and safety.

The other choices fall outside the recommended range for safe refrigeration. The first option is too low, potentially leading to freezing, while the third option extends into temperatures that can lead to inadequate safety for refrigerated items. The last option is not appropriate for refrigeration, as it signifies a freezing environment which is not suitable for fresh foods.
