Do peach pits contain arsenic

Peach pits do contain trace amounts of a cyanide compound. However in order to do any damage to yourself you would have t eat a lot of peach pits (theoretically). Peaches are not the only fruit to have cyanide related poisons, Apple seeds, cherry seeds and Nectarines all have these poisons as well, although I hear tell the concentration is less.

Be wary- their is enough poison to do significant harm to small animals, and even cattle. Reports have been made of Cows eating fallen peaches and getting very sick or dying.
