How does washing hands prevent from parasites such as Giardia lamblia?

Question

Even if we wash our hands, eating food which has Giardia’s cysts will infect us, am I right?

And if we won’t wash our hands, the cysts will get on our hands but we’re not little children to put our hands in mouth so how is this harmful?

The key is in food preperation and eating. It’s almost impossible to not lay hands on food when cooking and it’s very common to hold food in your hand when you eat it. Even utensils aren’t foolproof as you need to store and retrieve them, getting them contaminated with unwashed hands.

Regular hand washing just adds another layer of defense.
