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?

Not necessarily, but you could transfer the cysts to any food you touch or prepare.
