Final answer:
To prevent contamination of hot food displays, provide sneezeguard protection, clean utensils, hand sanitizer, and adequate ventilation.
Step-by-step explanation:
To prevent contamination of hot food displays, it is important to provide sneezeguard protection. Sneezeguards act as a physical barrier to prevent respiratory droplets from contaminating the food. This helps to maintain the hygiene and safety of the displayed food. Other measures such as using clean utensils, maintaining proper hand hygiene with hand sanitizer, and ensuring adequate ventilation can also contribute to preventing contamination.
