Which food does NOT require refrigeration at 41 °F?

UHT creamers, or ultra-high temperature creamers, are designed to be shelf-stable and do not require refrigeration until after they have been opened. The UHT process involves heating the cream to a very high temperature for a short time to destroy harmful bacteria, which gives it a long shelf life without the need for cold storage. This makes UHT creamers convenient for situations where refrigeration is not available or practical.

In contrast, tofu, an open container of garlic in oil, and sliced or cut cantaloupe all require refrigeration to prevent the growth of harmful bacteria and to maintain freshness. Tofu is a perishable product, garlic in oil poses a risk of botulism if not refrigerated, and cut fruits can harbor bacteria if not stored properly. Thus, UHT creamers stand out as the only option that does not require refrigeration at 41 °F.
