At this stage, it can be readily mistaken for a rather robust fern, though there is no relation.  The foliage also resembles that of a carrot, which it is related to.  But note that all parts of the plant are toxic to ingest.  It is not poisonous to the touch, but if you do touch it, I advise washing your hands thoroughly before touching any food!
