Confused by the ingredient list on your kitten’s food? You’re not alone. Marketing pet foods that have “human-grade ingredients” is becoming commonplace. While appealing to many pet owners, it is important to be aware that the term “human grade” has no legal definition and is used primarily for marketing purposes.
Foods, typically meats, are labeled either as “edible” or “inedible, not for human consumption.” Once a food leaves the human food chain, even if it is of outstanding quality, it has to be labeled “inedible, not for human consumption.” Therefore, meats used in pet food must be labeled as “inedible,” regardless of the source or quality of the meat. The only way to make a pet food with ingredients deemed “edible” is to never let the meat leave the human food chain and actually manufacture the pet food in a human food facility and transport it using human food trucks. Therefore, advertising a product as containing “human-grade ingredients” is untrue if it is not manufactured in a human food facility. However, just because a pet food isn’t marketed as being “human grade” does not mean that the ingredients are poor quality.
Ethoxyquin is a synthetic antioxidant (artificially manufactured from other elements) that is approved for various uses. It is approved and regulated by the Food and Drug Administration (FDA) and the Association of American Feed Control Officials (AAFCO) for use as a preservative in animal feeds. Pet food manufacturers have been using ethoxyquin to prevent rancidity and maintain the nutritional quality of their products for more than 35 years.
Ethoxyquin remains stable at the high temperatures required to process pet foods during extrusion. It is important in protecting fats and oils from degrading, losing available calories, and becoming rancid.
Despite the fact that all studies conducted to date prove that ethoxyquin is safe for use in all animal foods when used at approved levels, rumors continue to circulate to the contrary.
Individuals who seek to discredit the use of ethoxyquin will often cite certain studies that showed toxic effects in animals fed ethoxyquin. What these individuals fail to point out is that the animals in these studies were given excessive amounts of ethoxyquin—20 to more than 50 times the maximum limit—before negative effects were exhibited.
