All plant parts of Poison Hemlock, especially seeds, contain highly poisonous alkaloids toxic to all classes of livestock and humans. Human deaths have occurred from harvesting and mistakenly consuming the roots as wild carrots or parsnips. The plant may act as a pioneer species, quickly colonizing disturbed sites and displacing natives during early successional areas.
