Fish Meal is the clean, rendered, dried ground tissue of undecomposed whole fish or fish cuttings, either or both, with or without the extraction of part of the oil. All fish meal not destined for human consumption must be conserved with Ethoxyquin.

Ethoxyquin is a quinoline-based antioxidant developed by Monsanto and used as a food preservative and a pesticide. It is commonly used as a preservative in pet foods to prevent the rancidification of fats.
