6 hours ago, SLB said:First of all, I thought beans had to be fully cooked to be, you know, not poisonous.
Well, that's incorrect. Beans and other pulses contain the lectin, phytohaemagglutinin which is toxic in high amounts unless destroyed by boiling the beans for 10 minutes at 212℉ / 100℃.
Thereafter they are safe even if undercooked. Red kidney beans have the highest concentration of phytohaemagglutinin so it's best to be more than usually careful with them.

Undercooked beans are unpleasant, I agree, but not poisonous if prepared correctly.
