After coughing into a tissue and throwing it away, what must a line cook do before handling food again?

Coughing or sneezing, even into a tissue, contaminates the hands, so the cook must wash his hands before returning to food. A tissue helps, but holding and discarding it still transfers respiratory secretions and pathogens to the hands, so it does not leave them clean. A mask covers the mouth and does nothing for hands that are already contaminated, and waiting for droplets to settle removes nothing from the skin.
