Quote: Russ, where are you getting that info? It really is at odds with my experience of feeding green beans/raw shell beans, and the inherited livestock feeding patterns of my family (for poultry, cattle, sheep and pigs) although we are Blue Lake snobs, and I suspect that other cultivars have different chemical profiles. The only cultivated food bean I know for sure that has phytotoxic effect is fava beans which are antagonistic to people with sickle cell disorder and thalasemia and the monotypic carriers of those disorders.
There are a bunch of legumes that have toxic seeds (some vetches, all Lathyrus sweet peas) or whole plants that are toxic when mature (one of which was implicated in the death of the Into the Wild guy) but Phaseolus vulgaris and its cultivars is not something I've seen warnings about until right here in this thread, this week. We have, over the years, grown farm-stall size commercial beans, and fed the over-ripe fruits to cattle and pigs, had the Thousand Banty Army bottom prune all the pole beans, and this summer lost about 2/3 of the Blue Lakes to deer.
Sorry about my skepticism, but it's at odds with sixty years of observed experience.
I've known about dried beans for years. Easy to google for that information. Try beans toxic or hemogluttein. The reason it is not well known in the US is that beans are not as much a staple as they are in Europe. Here's the FDA site.

I was surprised and got schooled in the topic, of green beans, last year, here:

btw- I am not advocating that beans are in the league as cyanide laced kool-aid. Just in the sharing of knowledge.
