Final answer:
The issue with preparing tuna salad sandwiches directly from a hotel pan could potentially be cross-contamination if proper food safety protocols are not followed.
Step-by-step explanation:
The problem with a food handler pulling a hotel pan of tuna salad from the cooler and using it to prepare six tuna salad sandwiches might be related to cross-contamination. This occurs when pathogenic microbes transfer from one food item to another, typically through direct or indirect contact. It is a serious concern in food safety, as it can lead to foodborne illnesses. To prevent cross-contamination, good sanitary practices should be followed, including using separate utensils and surfaces for different types of food, and ensuring that all food handlers are properly trained in food safety protocols.
Given the options presented, if the scenario does not mention any violation of proper procedures or hygiene, and the food handler is following the correct recipe and food handling instructions, then the issue identified in the options would most likely be (c) cross-contamination.
