What is the minimum hot-holding temperature for macaroni and cheese on a buffet?

• A. 140 degrees
• B. 135 degrees
• C. 125 degrees
• D. 150 degrees

Answer: (B)

Keeping hot-holding foods at the right temperature is essential to prevent bacterial growth. The danger zone for growth is roughly from 41°F to 135°F, so foods should be kept at or above 135°F to stay out of that range. Macaroni and cheese, being dairy-rich and moist, is especially prone to rapid bacterial growth if it sits too long in the danger zone. Setting the hot-holding equipment to 135°F or higher keeps the dish out of the temperature window where pathogens multiply, making 135°F the minimum safe holding temperature. Higher temperatures such as 140°F or 150°F are also safe, but they aren’t the minimum. If it stays at 125°F, it would be unsafe because it falls inside the danger zone long enough for bacteria to grow.
