What is the maximum recommended time perishable food can safely be left at room temperature (between 40°F and 140°F or 4°C and 60°C) before it should be refrigerated or discarded?
✓ Correct Answer: Option C
The 'Danger Zone' for bacterial growth is between 40°F and 140°F (4°C and 60°C). Perishable foods should not be left in this temperature range for more than 2 hours to prevent rapid bacterial multiplication and reduce the risk of foodborne illness.
