If the beans are bubbly, smell yeasty or of rotten eggs, they are likely bad. If they have been mishandled and left unrefrigerated for some time, you might not be able to tell if they are safe to eat since some pathogenic microorganisms can grow without leaving telltale signs.
Cooked pinto beans are a potentially hazardous food and should be treated as such. In other words, after cooking, they should be refrigerated within 2 hours or less. Use them up within a few days.

If there is any doubt, there's NO doubt; throw it away. There is no point in taking chances with spoiled food.
I would think so. If it is discolored it probably has gone rotten. If you are talking about dark red or black, it might just be over done. If you are talking about yellow or green with fuzz, then yes, It is spoiled. :)
They smell like ammonia after they're cooked. That's why lobsters are usually cooked alive, because they deteriorate very quickly after death. And obviously, if you only have the tail, the lobster is dead.
It usually goes into a solid block if it i spoiled.
Sliminess, off-odor and unusual colors will tell you if mashed potatoes are spoiled.
If several parts of the steak are black.
They are spoiled when they are brown and slimy.
To tell if a like is spoiled it will have browny Blacky large spots on it and will be really soft and easy to squeeze
You can tell if a smoked turkey leg is spoiled in a few ways. The biggest way is that it smells bad.
sounds weird, but you you can add a can of black beans to a brownie mix. That's it. Just black beans - put them in the blender for a bit first, then combine the beans and the mix and bake. Yeah, you can tell that it's not quite what it's supposed to be, but it is better for you.
I'm not quite sure what you mean by if soaked beans are spoiled. If you soaked them and forgot about them they are probably fine unless they look weird, smell bad or have mold. If you mean how to tell if they are old, I would just cook them. If they don't soften they are old.
If a pork loin is spoiled it will have a foul smell and color. Throw it away because it is unsafe to eat spoiled food.
