Since enactment of the Agricultural Improvement Act of 2018 (the “2018 Farm Bill”), confusion has run rampant over when and where hemp or hemp produced cannabidiol (CBD) can legally be used. Animal food and feed are no exception. Developments at the U.S. Food and Drug Administration (FDA), as well as the actions taken by the Association of Animal Feed Control Officials (AAFCO), should be of particular interest to animal feed and pet food manufacturers interested in expanding into the so-called green rush.  Industry participants should take notice of these changes and evaluate the impact they have on their businesses.
