When working with food, it is recommended that food handlers drink from a covered cup with a straw. This is to prevent hand contact with the area that is being drank from and to avoid the possibility of the drink splashing onto the food or work area, which could contaminate the area. The drink should be stored away from the food or prep areas. Some regulatory authorities allow food handlers to drink from a covered container with a straw while in prep and dishwashing areas, but the drink must be stored so that it cannot spill onto food or food-contact surfaces. It is important to contact your local health department for specific regulations.
For example, according to Hawaii Restaurant Association, "food handlers drink from a covered cup with a straw" .
