What is the safe refrigerator storage temperature range?

• A. 0-2°C
• B. 4-7°C
• C. 1-4°C
• D. 8-10°C

Answer: (C)

Keeping refrigerated foods at a cold, steady temperature slows the growth of harmful bacteria and helps preserve quality. The safe range to aim for is about 1–4°C. This is low enough to keep bacterial growth in check (well below the 5°C threshold where the danger zone begins to enable faster growth) but above freezing, so most foods don’t suffer texture or quality issues from ice formation. A higher range, like 4–7°C or 8–10°C, is too warm and allows bacteria to multiply more quickly, increasing the risk of spoilage and foodborne illness. A range that reaches 0°C can cause some foods to freeze and may not provide consistent protection, so 1–4°C is the best balance.
