Common questions
How long does potato salad last in the fridge?
3–5 days in the refrigerator at 40°F (4°C) or below, according to USDA FoodKeeper data.
Can you freeze potato salad?
Freezing isn't recommended for potato salad; the texture and quality suffer.
How can I tell if potato salad has gone bad?
Throw it 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.
