A report from the Kansas State University Department of Agricultural Economics found that 2009 mandatory country-of-origin labeling (MCOOL) legislation has not significantly impacted demand but has increased costs for producers.  The study used retail grocery scanner data, an online survey and in-person interviews to arrive at its conclusion. Only 23 percent of online survey respondents were aware of MCOOL, and nearly two-thirds of respondents did not know if MCOOL was a law. Given the lack of impact on demand and the significant cost of compliance, the report suggests, there has been an aggregate economic loss for the US meat and livestock supply chain.
