If food that is being held hot for service has been below 135°F (57°C) for 4 hours, it should be discarded to prevent the risk of foodborne illness. Food cannot be safely reheated after being in the danger zone (between 41°F and 135°F) for that duration. It's essential to regularly monitor and maintain proper holding temperatures to ensure food safety.
