Currently, animal foods in the U.S. are only permitted to make claims relating to nutrition, taste, aroma or their technical effect.  Unlike the EU, any claims relating to production or performance, or to environmental benefits for example, are regulated as animal drugs.  Innovative products are therefore, often struggling to reach the market in the U.S.  An example of products impacted, are those making environmental claims such as reduced methane emissions.  Others such as probiotics are unable to convey the potential benefits on feed conversion rate, and milk or egg production to the end users.  Recognizing these limitations and that feed ingredients are evolving, the Center for Veterinary Medicine (CVM) is in the process of updating its Policy and Procedures Manual 1240.3604 for regulating animal foods with drug claims.  As part of this work, the CVM is hosting a virtual listening session on October 18, 2022 to allow stakeholders and the public to share information on this topic with the Agency.  Additionally, the CVM is accepting written comments on this topic until November 17, 2022.
