1 hour above 90°F (32°C)
Overnight: discard
Food that sat out overnight has spent far longer than 2 hours in the danger zone (40–140°F).
Quick answer
Whipped topping (aerosol can) left at room temperature for more than 2 hours (1 hour above 90°F / 32°C) should be thrown away. Bacteria multiply fastest between 40°F and 140°F, and reheating does not remove every toxin they make.
