Erysimum cheiranthoides (Scientific name)

General poisoning notes:

Wormseed mustard (Erysimum cheiranthoides) is a naturalized herb found across Canada in fields and waste places. It contains large quantities of glucosinolates, which release allylisothiocyanate upon hydrolysis. Cattle and swine were poisoned in Canada when feeds were contaminated with sufficient quantities of seed from wormseed mustard plants (Kingsbury 1964, Palechek 1986).
