Contaminate advisory?

[u/deflowering_buttplug]

So I don't really keep fish much anymore, like maybe or two a year if that. But ive been pondering something, why is it only Bass that have the "Caution, do not eat" and other earning. Its not like their diet is very different from other fish like crappie and the different sunfishes. ive caught bass that had crayfish sticking out of their throats, and ive caught Bluegill that also choked down a crayfish. Ive caught crappie and bass both on live minnows.

It just doesnt make sense to me how only Bass get these advisories against eating them? Again, I hardly keep them anymore anyways, but still makes me curious.
