Take care with dried legumes, many contain poisonous lectins and they should be soaked overnight first, with the soaking water disposed of and thoroughly rinsed before cooking

Phytohaemagglutinin is destroyed by sufficient heating. It is a serious danger with slow cookers, but not with pressure cookers. The FDA publishes a book on food safety:

https://www.fda.gov/downloads/Food/FoodborneIllnessContamina...

"PHA is destroyed by adequate cooking. Some variation in toxin stability has been found at different temperatures. However, Bender and Readi found that boiling the beans for 10 minutes (100°C) completely destroyed the toxin. Consumers should boil the beans for at least 30 minutes to ensure that the product reaches sufficient temperature, for a sufficient amount of time, to completely destroy the toxin."

It's destroyed by high temperatures, like you find in a pressure cooker. Slow cookers are a danger but pressure cookers aren't.
