What is the first step that food service workers should complete if they cut themselves, before they contact a supervisor?

In the scenario described, the priority for food service workers who have cut themselves is to cover the wound to reduce the risk of bloodborne contamination. This step is crucial because an open wound in a food service environment can lead to contamination of food products and surfaces, posing a health risk to customers and staff. By covering the wound, workers can help prevent the spread of pathogens and maintain a safer food preparation environment.

Once the wound is covered, it is appropriate for the worker to then inform a supervisor or call for assistance, ensuring proper medical attention is sought if necessary. The other options, while important in their own right, do not prioritize the immediate need to prevent contamination, which is critical in food safety protocol.
