Which food must be stored at a temperature of 41°F or lower?

• A. Lettuce and tomato sandwich
• B. Ham-and-cheese sandwich
• C. Peanut butter and jelly sandwich
• D. Canned beans

Answer: (B)

Foods that contain meat or dairy need to be kept cold to slow bacterial growth. The ham-and-cheese sandwich has both ham (meat) and cheese (dairy), making it highly perishable and requiring storage at 41°F or lower. The other items are shelf-stable or don’t pose the same immediate safety risk: canned beans can stay at room temperature until opened, and peanut butter with jelly uses ingredients that don’t require refrigeration for safety. While produce like lettuce and tomato is perishable, the key safety distinction here is the presence of dairy and meat, which makes cold storage essential.
