Common questions
How long do juice and boxes last in the fridge?
8–12 days once opened in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
How long do juice and boxes last at room temperature?

How can I tell if juice and boxes have gone bad?
Throw them out if you see mold, a slimy texture, an off smell or an odd color. For anything perishable, go by the storage time rather than smell: bacteria that cause food poisoning don't usually change how food looks or smells.
