Irreversibly (or irrevocably) contaminated was a Peacekeeper term for an individual who had come into contact with an unknown life form, either willingly or unwillingly. When something of the like occurred, Peacekeepers risked being tagged "irreversibly contaminated". ("Premiere") If deemed as such, the Peacekeeper in question was executed or banished. ("PK Tech Girl")
The concept was also applied to Sebaceans who entered into unions with other species. ("Mind the Baby") However, the Peacekeepers did not have legal authority to take action in circumstances where the Sebacean was not a Peacekeeper themselves. While they once did, said laws were relaxed at around the same time as the formation of the Breakaway Colonies. ("Brotherly Hate")
