Final answer:
The correct action for a food worker who heated fried rice for hot holding and finds it at 167°F (75°C) after an hour is to continue to hold the rice at that current temperature, as it is safely above the danger zone for bacteria growth.
Step-by-step explanation:
When a food worker reheats fried rice for hot holding and measures the temperature at 167°F (75°C), they should continue to hold the rice at the current temperature. This temperature is above the danger zone of 40°F to 140°F (4°C to 60°C), where bacteria grow most rapidly. Since the rice is well above the minimum temperature required to prevent bacterial growth, reheating it to a higher temperature or discarding it is unnecessary, and placing it in a cooler would be counterproductive for hot holding.
