One of the basic principles of toxicology is "the dose makes the poison".

From an OSHA perspective, "toxic" means (amongst other things) a mean-lethal-dose (LD50) of up to 500 mg per kilogram of bodyweight when ingested orally in lab rats.

There's all kind of stuff that doesn't meet the standard of toxic that you still wouldn't want to eat.

That's a given, but this this is something where it comes in a small jar to sprinkle with and a single spoonful is dangerous.


And there's stuff that is toxic that you do want to eat. Check your multivitamin, there's stuff in there that would kill you at that level.


Also, for example, aspirin.


So at LD50 of 508 mg/kg you could call it "barely non-toxic"
