The issue for the males is that they have overactive testosterone glands that give the meat a rancid flavor.
Also, in some areas their meat is inedible because they've eaten too much repellant and animal poison.
These hogs have blue tissue and viscera from eating dyed rat poison and ingesting so much of the dye that it actually permeated their flesh.
Non-dyed poisons would have the same bioaccumulation, but invisibly.
