If you ask this question to a lot of ordinary people without a green thumb/knowledge in botany they would likely say ''I don't know''. It's not exactly something that is brought to awareness like salmonella, tetanus, rabies etc.. and for that reason would not be able to give a definitive answer (all be it, the op questions scope is narrow). Maybe I'm projecting, none the less It's not something I've ever given thought to or recall learning about, one way or the other.
Chin up lad, shit happens.
