The Association of American Feed Control Officials, Inc. (AAFCO) announced to its members and to the feed industry on Aug. 4, 2003, that kava should not be used as an ingredient in animal feeds. An enforcement strategy event for kava in animal feeds, recommended to begin on Dec. 2, 2003, follows a notification period informing manufacturers and distributors of animal feed that many of the ingredients they are using might not be in compliance with federal and state commercial feed laws.

AAFCO’s Enforcement Strategy for Marketed Ingredients (ESMI) Working Group identified kava as a feed ingredient that could pose a health and safety concern when consumed by animals. The ESMI Working Group based its selection on published scientific information provided by the U.S. Food and Drug Administration’s (FDA) Center for Veterinary Medicine. Kava is banned in Canada and in some European countries due to reports of serious side effects in humans, primarily liver damage. A public health advisory for kava was issued by the FDA’s Center for Food Safety and Applied Nutrition on March 25, 2002
