What is the typical refrigerated storage temperature for pasteurized milk?

• A. 10°C (50°F)
• B. -5°C (23°F)
• C. 4°C (39°F) or lower
• D. Room temperature

Answer: (C)

After pasteurization, keeping milk cold is essential to slow any surviving microbes and preserve quality. The typical refrigerated storage temperature is 4°C (39°F) or lower. At this temperature, bacterial growth is greatly slowed, which helps extend shelf life and reduce spoilage risk while maintaining flavor and texture. Storing at around 10°C is warmer than ideal, so bacteria multiply more quickly and milk spoils sooner. Freezing at -5°C isn’t considered standard refrigeration and can change the milk’s texture and mouthfeel, even though freezing is another way to store milk longer. Leaving milk at room temperature allows rapid microbial growth, increasing spoilage and potential safety concerns.
