The Association of American Feed Control Officials, Inc. (AAFCO) has recommended a nationwide enforcement event for comfrey in animal feeds to begin on March 3, 2003. At the AAFCO Annual Meeting in August 2002, AAFCO announced that comfrey, determined to be a health and safety concern in animals, is recommended for removal from all animal feeds.

This AAFCO-recommended enforcement event follows a lengthy notification period of informing manufacturers and distributors of animal feeds that many of the ingredients they are using may not be in compliance with federal and state commercial feed laws
