Soaking them too long, probably.
If you store the beans in an air tight container, they can stay good for years. Dried beans are a good staple to have in your diet. Keep them dry until ready to cook.
Cooked string beans should not be left unrefrigerated for more than two hours, or only one if the ambient temperature is very warm.

Yes, they can eat raw green beans. It is not good for them to eat cooked vegetables. Long leafy greens are preferred.
Cooked chili beans can be left in the fridge for up to 3 days. The beans will need to be in a covered container to last for the 3 days.
Cooked beans should be used within 2-3 days.
I have never seen pinto beans spoil in less than a period of about two hours however in my years of cooking you would have to leave them out of the refrigerator for several hours before they would began to spoil. Beans are a staple food in the South and they would have to stay out all night in some cases before spoilage would sat in however If I intended on selling the beans to the public I would follow the 2 HOUR RULE and just cook a fresh pot.
