A manager plans a weekend omelet station where a cook prepares eggs in front of guests, next to an open tray of diced toppings guests scoop themselves. What protection does the topping tray need?

Any food displayed for customer self-service must be protected by packaging, a counter guard, or another effective barrier, with proper utensils provided. Labeling helps guests with allergens but is not a barrier, moving air does not stop a cough or a reaching hand, and the cook's presence at the station does not shield the open tray from guest coughs, sneezes, and hands.
