What Celsius temperature should dairy be stored in the refrigerator to stay safe?

• A. 0°C
• B. 4°C or below
• C. 8°C
• D. 10°C

Answer: (B)

Dairy is highly perishable, so it needs to stay very cold to slow the growth of bacteria and keep it safe to eat. The recommended fridge temperature is 4°C (40°F) or below. Keeping dairy at or under this temperature slows spoilage and reduces the risk of foodborne illness. Temperatures higher than that, like 8°C or 10°C, allow bacteria to grow more quickly, increasing spoilage risk. 0°C would freeze dairy, which changes texture and is not how dairy is typically stored in the refrigerator. So, 4°C or below is the best practice for safe refrigeration.
