Many health professionals advocate washing hand before dinner. But is it necessary if we do not use our hands to directly touch the food we are going to ingest? Can bacteria move from our hands along the utensils or along nearby air towards our mouth?
Because its a good habit as your hands might end up touching your mouth or food when you are eating food using spoon or something. Plus eating with dirty hands no matter whether they will touch food or not doesn't just feels right. That's one of the most important reason that people usually wants to feel comfortable while eating and they want their hands to be clean even if they will use a spoon or chopstick. Its also a good idea to just be safe than sorry.
