How long can linguini with white clam sauce be left out?

Linguini with white clam sauce should not be left out at room temperature for more than two hours. Bacteria can rapidly grow in food left out beyond this time frame, increasing the risk of foodborne illness. If the temperature is above 90°F (32°C), it should be discarded after just one hour. To ensure safety, it's best to refrigerate leftovers promptly.
