Final answer:
It is important to maintain the refrigerator at the proper temperature of 35°-38°F to inhibit bacterial growth and ensure food safety. Using a thermometer to monitor the temperature is recommended. Freezing and thawing should be done properly to preserve food quality.
Step-by-step explanation:
Keeping the refrigerator at the proper operating temperature of 35°-38°F is important for food safety. Bacteria generally multiply most rapidly at temperatures between 40 and 140 degrees F, so maintaining a temperature below 40 degrees F inhibits bacterial growth.
Using a thermometer to monitor the temperature is recommended. If the temperature in the refrigerator goes above 40 degrees F for two hours or more, the food may no longer be safe to eat.
Additionally, freezing foods at 0 degrees F or below preserves them, but thawing should be done slowly in the refrigerator or quickly in the microwave or cool water. Refreezing food that has thawed is not recommended.
