Question: are raw cannellini beans poisonous?
Answer: Cannellini beans These, like red kidney beans, have high levels of a specific toxin called Phytohaemagglutinin (also known as kidney bean lectin) when raw. To rid the beans of toxins, you need to pre-soak, then boil them for at least 10 minutes, though the FDA recommends no less than 30 minutes to be on the safe side.
