From case histories it is known that the toxin is stable, as four-month-old pickled quail have been poisonous. Humans vary in their susceptibility; only one in four people who consumed quail soup containing the toxin fell ill. The toxin is apparently fat-soluble as potatoes fried in quail fat have proven poisonous themselves. Coniine from hemlock consumed by quail has been suggested as the cause of<unk> , though quail resist eating hemlock. Hellebore has also been suggested as the source of the toxin. It has also been asserted that this evidence points to the seeds of the annual woundwort (Stachys annua) being the causal agent. It has been suggested that Galeopsis ladanum seeds are not responsible.
