The National Animal Identification System (NAIS) has been a widely discussed concern of livestock owners and producers since it was first conceived. The movement of animals and their products has created a need to identify sources of disease outbreaks and to assure consumers of product quality and safety to reduce possible individual firm and industry losses. This issue is sometimes confused with COOL, Country of Origin Labeling, which is an economically motivated issue, and is focused on differences consumers might place on domestically produced beef. As a policy matter, NAIS is basic in concept but has many complex hurdles to its implementation.
