When partially cooking a large batch of chicken stir-fry, what is the required action immediately before cooling to ensure food safety?

• A. Freeze immediately
• B. Refrigerate immediately
• C. Add oil
• D. Heat the food for no longer than one hour

Answer: (D)

The main idea is to minimize the time food spends in the temperature danger zone by finishing the cooking to a safe temperature as quickly as possible before cooling. When you partially cook a large batch of poultry, you want to ensure any bacteria that may have started multiplying are killed promptly, and then you can begin the cooling process. The instruction to heat the food for no longer than one hour emphasizes finishing the heating step quickly rather than lingering at warmth, which helps prevent bacterial growth before you move to rapid cooling. Freezing or refrigerating immediately before finishing heating wouldn’t guarantee that the food has reached a safe internal temperature, and adding oil doesn’t address safety concerns.
