Canned beans contain no liquid? I recently opened two cans of pinto beans from the same brand (whole foods organic). One can looked perfectly normal with a fair amount of liquid and no visible beans until drained.

The second can however was quite dry. The beans looked hydrated and cooked, but there was almost no excess liquid in the can.

Any idea what caused this? Would these be safe? I threw them out, but curious for the future.

Thanks in advance
You were right to throw them out, no liquid was a sign that something went wrong in processing and therefore a safety concern. When it doubt, throw it out!
