Final answer:
Food being reheated for immediate service must reach 165°F (74°C) to ensure safety by minimizing the risk of foodborne illnesses.
Step-by-step explanation:
If food is being reheated for immediate service to a customer, it may be served at any temperature as long as it reaches 165°F (74°C). It is crucial for food safety to reheat foods to this temperature to minimize the risk of foodborne illnesses. Foods that are left at temperatures between 4°C (40°F) and 60°C (140°F) for over two hours should be discarded due to the increased potential for bacterial growth. Therefore, quickly reheating to the adequate temperature is essential before serving to ensure safety.
