Final answer:
The maximum temperature for transporting cold TCS foods should be 41°F (5°C) or lower to prevent bacterial growth and foodborne illnesses.
Step-by-step explanation:
The maximum temperature for transporting cold TCS (Time/Temperature Control for Safety) foods should be 41°F (5°C) or lower. This is because bacteria multiply most rapidly at temperatures between 40°F and 140°F (4°C and 60°C), so it's important to keep perishable foods below that temperature range to prevent bacterial growth and foodborne illnesses. Refrigerators should be kept at or below 40°F (4°C), and any perishable foods left between 40°F and 140°F for more than two hours should be discarded.
