On June 23, 2016, Senators Pat Roberts (R-Kan.) and Debbie Stabenow (D-Mich.) introduced a compromise bill that would create a mandatory, national labeling standard for GMO foods. Although this bill is the first mandatory legislation introduced in Congress it falls short of what consumers expect — a simple at-a-glance disclosure on the package. As written, this compromise might not even apply to ingredients derived from GMO soybeans and GMO sugar beets.
