In the US, feed regulations are enforced by state and federal regulatory officials who provide subject matter expertise in animal science, animal nutrition, feed label compliance, field operations for inspection staff and program administration.  AAFCO provides a forum for these regulatory officials to come together and create model guidance to ensure that the regulation of animal feeds is as uniform as possible from state to state.  AAFCO Membership includes not only US state and federal regulatory officials but has grown to include international membership of Canada and Costa Rica.
