I've been scouring the Core Rulebook and I can't find an answer to a question that's going to be crucial for a game I'm planning: is there any way to detect an ingested poison in food or drink other than magic? Is there a Perception check to smell it, for example, and if so, is the DC codified?
If this isn't in the rules, I think it might make a good feat. Maybe a skill feat or an ancestry feat.
