Final answer:
The internal temperature of products in a holding oven must be at least 140 degrees Fahrenheit to ensure food safety.
Step-by-step explanation:
According to food safety guidelines, the minimum safe internal temperature for holding hot foods is 140 degrees Fahrenheit (60 degrees Celsius). This temperature helps prevent the growth of bacteria and ensures that the food remains safe to eat.
It's important to regularly check the internal temperature of food using a food thermometer to ensure that it has reached the appropriate temperature before serving or holding it in the oven.
