Steve - Oh, the temptation to point out what a poisonous swine you are, so obviously they wouldn't make you sick, etc... ;-) It was probably raw French beans that did for me. I've grown both regularly, but broad beans are an early crop & I think this incident would have been later in the year.

As for why I would eat raw French beans? Because I grew them! And because I was making a salad!! And there they were!!! Never again... :o

Broad beans, incidentally, do also contain Muck, but apparently in "relatively low concentrations", which may explain why you've never experienced any adverse reaction. Broadly (see what I did there? ;-) ) speaking, in light of previous experience, I'd be rather reluctant to eat a raw bean these days. To each their own!
