What degrees should reused food in a buffet be?

Reused food in a buffet should be maintained at safe temperatures to prevent foodborne illnesses. Hot foods should be kept at 140°F (60°C) or above, while cold foods should be stored at 40°F (4°C) or below. It's essential to monitor these temperatures regularly to ensure food safety throughout the serving period. Any food that has been left out for more than two hours should be discarded.
