Few things have been more contentious in recent years within the U.S. meat and livestock industry than mandatory country of origin labeling (MCOOL). The debates around MCOOL have a long history now encompassing the originally implemented rule in 2009, the modified rule of 2013, and multiple rounds of WTO (World Trade Organization) assessment regarding international trade appropriateness. The on-going dispute has centered in large part around diverse views on underlying economic impacts on stakeholders throughout the meat and livestock supply chain.
