The USDA Agricultural Marketing Services is taking comments on the voluntary label "naturally raised." You can find more information on the USDA AMS News Release or at the Federal Register. Comments must be submitted to USDA by January 28th for consideration.
Recently, other voluntary labels, such as antibotic free, have come under scruntiny. USDA revoked Tyson's use of the claim "antibiotic free" based on definiations of specific feed additive. 'Organic' has federal regulations, 'antibotic free' has specific definitions, and now, is your chance to comment on the development of a "naturally rasied" definition at the federal level.
