To effectively prevent infection, wounds on food handlers should be covered with an impermeable barrier. This method is crucial because it protects the wound from external contaminants that could lead to infections and prevents any potential pathogens from the wound from contaminating food products. An impermeable barrier helps to create a clean and secure environment for both the food handler and the food being prepared, reducing the risk of cross-contamination.

Using a standard adhesive bandage may not provide sufficient protection, as these often aren't designed to be waterproof or resist bacterial infiltration. Leaving a wound open could expose it to bacteria and dirt, increasing the risk of infection for the food handler and for those consuming the food. Ignoring the wound until healing occurs poses significant health risks both for the individual and for food safety. Therefore, using an impermeable barrier is the most effective option for maintaining hygiene and ensuring safety in food handling.
