Queen Anne's Lace appears to be the same species (Daucus carota) as domesticated carrot; I would assume therefore that the tops are safe to feed? I certainly hope so, since we have a heck of a time growing carrots here but cannot get rid of the Queen Anne's Lace.
It would probably be unwise for those who live in areas where water hemlock (genus Cicuta) grows to gather Queen Anne's Lace for food unless they are experts at telling the two apart, as the two are similar in appearance.
