 In April 2012 , the USDA received requests from beef processors to allow voluntary labeling of products with the additive , and stated it plans to approve labeling after checks for label accuracy . Both BFI and Cargill made plans to label products that contain the additive to alleviate these concerns and restore consumer confidence . Following the USDA announcement to allow choices in purchasing decisions for ground beef , many school districts stated that they would opt out of serving ground beef with LFTB . By June 2012 , 47 out of 50 U.S. states declined to purchase any of the product for the 2012 – 2013 school year while South Dakota Department of Education , Nebraska , and Iowa chose to continue buying it .
