How long can you keep potatoe salad out inside a home?

Potato salad should not be left out at room temperature for more than two hours. If the temperature is above 90°F (32°C), it should be discarded after just one hour. Bacteria can grow rapidly in perishable foods when left unrefrigerated, increasing the risk of foodborne illness. It's best to keep potato salad chilled until serving to ensure safety.
