General poisoning notes:
European spindletree (Euonymous europaeus) is an ornamental shrub that can grow in the warmer parts of Canada. The shrub has poisoned children as well as goats, horses, and sheep. Children are attracted to the mature fleshy orange fruits, which contain seeds with cardiac glycosides and alkaloids. Children have become quite ill. Fatal poisoning has occurred in two horses after they ingested shoots of this plant (Frohne and Pfander 1983, Cooper and Johnson 1984, Lampe and McCann 1985).
