At what temperature should milk be stored to stay safe?

• A. 34–40°F (1–4°C).
• B. 60–70°F.
• C. -4–14°F.
• D. 50–60°F.

Answer: (A)

Milk stays safe when it’s kept cold, because cool temperatures slow the growth of bacteria that can cause spoilage and illness. Refrigerating milk at 34–40°F (1–4°C) provides a temperature that's cold enough to inhibit bacterial growth while staying within a range that preserves quality for a reasonable period.

Temperatures in the 60–70°F range are warm enough for bacteria to multiply quickly, increasing the risk of unsafe milk. The 50–60°F range is also not cold enough to reliably prevent bacterial growth. Freezing at -4–14°F can preserve milk for longer, but once thawed, it can change texture and you should use thawed milk promptly and not refreeze it. For everyday safety, keep milk in the fridge within the 34–40°F range.
