Final answer:
The commercially processed cheese sticks must be reheated to a minimum internal temperature of 74 degrees Celsius (165 degrees Fahrenheit) to ensure food safety.
Step-by-step explanation:
The commercially processed cheese sticks that will be hot-held on a buffet must be reheated to a minimum internal temperature of 74 degrees Celsius (165 degrees Fahrenheit) according to food safety guidelines. This ensures that any harmful bacteria present in the cheese sticks are killed, reducing the risk of foodborne illness.
It is important to use a food thermometer to accurately measure the internal temperature of the cheese sticks. Simply reheating the cheese sticks in an oven or microwave until hot may not be sufficient to reach the recommended temperature.
By reheating the cheese sticks to the specified temperature, you can confidently serve them on the buffet without compromising food safety.
