Question: 1 / 400

At what temperature should a refrigerator be maintained to ensure food safety?

30°F (-1°C) or lower

40°F (4°C) or lower

Maintaining the refrigerator at 40°F (4°C) or lower is crucial for ensuring food safety because this temperature range effectively inhibits the growth of harmful bacteria that can cause foodborne illness. Most pathogens thrive at temperatures above 40°F, so keeping food stored at or below this temperature helps slow down bacterial growth and prolongs the freshness of perishable items such as meats, dairy, and some vegetables.

Additionally, the USDA and food safety guidelines recommend this temperature to help prevent food spoilage and maintain the quality of food items for as long as possible. Regular monitoring of refrigerator temperatures can help ensure compliance with these safety standards, helping to protect public health.
