Q&A: What freezer temperature do I use for frozen foods?

Q&A: What freezer temperature do I use for frozen foods?

Q: My new freezer cools to 9°F at the recommended setting. If I change the setting, I can get to 0°F, but it runs more often and, presumably, uses more electricity. Is it safe to keep food at 9°F? —Marcia De Leon, Edgewood, NM

A: We recommend using whatever setting yields 0°F in the freezer. You’re right that the unit will run more often and will use more energy, but that is to be expected. Frozen-food labels say to store products at 0°F or colder; warmer temperatures reduce quality and shelf life.
