Pentobarbital in Pet Food in Pet Food

Grade F-5 ptsThe Dark Side of the Industry

What It Is

"Not an ingredient — a contaminant. AAFCO does not address it."

Health Impact

Pentobarbital is the drug used to euthanize animals. The FDA confirmed its presence in multiple commercially sold dog foods in 2002 and again in 2017-2018. It can only get into pet food one way: rendered euthanized animals. The agency has never required a recall solely on this basis, citing levels as "unlikely to cause adverse effects" — a position many vets and researchers dispute. This is documented by the FDA itself.

Why This Grade

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.
