What is the recommended refrigerator temperature for food safety?

• A. At or below 30°F (-1°C)
• B. At or below 40°F (4°C)
• C. At or below 50°F (10°C)
• D. At or below 60°F (15°C)

Answer: (B)

The recommended refrigerator temperature for food safety is at or below 40°F (4°C). This temperature is crucial for slowing the growth of bacteria and other pathogens that can cause foodborne illnesses. By maintaining the refrigerator at this temperature, perishable foods such as meat, dairy, and vegetables are kept safe from spoilage and contamination.

Temperatures higher than 40°F can allow harmful bacteria to multiply rapidly, leading to a higher risk of foodborne illness. Therefore, keeping your refrigerator at or below this threshold is a fundamental practice in food safety, ensuring that foods remain fresh and safe to consume over time. Options suggesting temperatures above 40°F fail to provide the necessary protection against bacterial growth, making them less appropriate choices for food safety.
