After pasteurization, pasteurized milk must be refrigerated unless it is which type?

• A. UHT/aseptic milk
• B. Frozen milk
• C. Raw milk
• D. Shelf-stable packaged milk

Answer: (A)

After pasteurization, milk is generally kept refrigerated because pasteurization doesn’t sterilize the product. To be stored at room temperature without refrigeration, the milk must undergo ultra-high-temperature processing and be sealed in sterile, aseptic packaging. This combination kills or inactivates microorganisms more completely and prevents recontamination, allowing shelf-stable storage until opened. Once opened, it should be refrigerated. Raw milk isn’t pasteurized, frozen milk must be kept frozen, and standard pasteurized milk needs refrigeration, so the UHT/aseptic option is the one that allows unrefrigerated storage before opening.
