Step-by-step explanation:
Which is a way to prevent contamination of hot food on display in a self-serve buffet?
The correct answer is B. Using a sneeze guard. A sneeze guard is a transparent barrier that is typically placed over food on display to protect it from contamination by airborne pathogens. It acts as a physical barrier between the food and customers, preventing sneezes, coughs, or other contaminants from coming into direct contact with the food.
Letting customers serve themselves (option A) could increase the risk of contamination if customers do not handle the food properly. Keeping food uncovered (option C) also increases the risk of contamination by allowing airborne pathogens to come into direct contact with the food. Using the same utensils for different dishes (option D) can lead to cross-contamination and the spread of bacteria between different dishes.
