On June 23, 2016, Senator Pat Roberts (R-Kansas) and Senator Debbie Stabenow (D-Michigan) reached an agreement to solve the state-by-state labeling requirement for genetically modified foods (also referred to as genetically modified organisms, or GMOs) by setting a mandatory uniform national standard for biotechnology labeling of food. The senators' proposed bill would give several options to food manufacturers to comply with the mandatory disclosure requirements. The options include adding to the package certain text, a symbol, or an electronic link to a website. In the last case, the bill states the package could not include any denigrating text toward biotechnology and would require the use of the descriptive language, "Scan here for more food information." Very small companies would be exempt from compliance with the mandatory labeling requirement, and small companies would have the alternative of including a toll-free number and website instead of using a digital code. The disclosure requirement would apply to all human food, including some meat and poultry products, but would exclude foods where meat, poultry, and egg products are the main ingredient, or foods that are derived from an animal that ate bioengineered food. The mandatory requirements would also apply to dietary supplements. The bill also states that products certified GMO by USDA could be labeled as non-GMO, but products that are exempt from disclosure under the bill would not automatically be allowed to make non-biotech claims on their food.

The bill will need to pass the Agriculture Committee, the full Senate, and the U.S. House, which passed a bill last July establishing a voluntary labeling system for GMO foods. If the bill is finally approved, it will preempt other similar state laws, such as Vermont's law, which entered into force on July 1, 2016.
