"Permitted as an antioxidant preservative in pet food."
Originally developed as a pesticide and rubber stabilizer. Banned for human food use in the US and EU. The FDA received enough adverse event reports (liver damage, immune disorders, cancer) that it asked manufacturers to voluntarily reduce use in 1997. It is still legal in pet food. It does not always appear on labels — if a manufacturer buys fish meal already preserved with ethoxyquin, they are not required to disclose it.
Our most serious tier: a documented carcinogen finding, an outright ban in at least one country or species, or an unspecified source that can legally include 4D (dead, dying, diseased, disabled) animals. -5 pts deducted.
