PSA: You don't want to eat uncooked soaked dried bean residue (especially red kidney beans). Uncooked it contains phytohaemagglutinin (plant lectin) which is toxic to humans. After cooking via boiling or pressure cooking it reduces the toxin to safe levels. Do not slow cook.

Canned beans are pressure cooked typically. I'd be more comfortable with the canned liquid.

Neither really seems likely to get me sick though.
