Oh my god. Is this your version of being a vegan now? A neurotic (this is redundant) vegan?
This is something they would obsess over.
You are bigger than this. Obsess over what is in Jack Daniel's. I don't think anything untoward can grow in that poison mash. So you are safe there, except, of course, that it's alcohol and poison.
As disgusting as it sounds, I have read on the internet (not that it makes it really REAL) that excrement of female beetles is used in both shellac used on wood floors and some food glaze. I am going to say, yes. It is.
