Viewpoint: evaluating transparency and market consequences of the national bioengineered food disclosure standard in the United States

The 2018 National Bioengineered Food Disclosure Standard (NBFDS) mandated disclosure of bioengineered (BE) ingredients in regulated foods in the United States, with full compliance required by January 2022. The policy is intended to reduce information asymmetry by enabling consumers to infer BE status through mandatory labeling, alongside existing voluntary claims such as organic and non-GMO labels. This viewpoint paper concludes that the current design and implementation of the NBFDS do not fully support this transparency objective in practice. We show that several regulatory features weaken the inference mechanism linking disclosure to consumer understanding on which the policy relies, including evolving definition and terminology associated with BE foods, electronic and digital disclosure options, detectability-based exclusions for highly refined products, exemptions from mandatory disclosure, and limited ingredient specificity. As a result, under the current design, mandatory BE labeling increases consumer search costs and cognitive burden while creating implementation challenges for industry. These findings underscore the importance of careful policy design in achieving effective transparency. Continued evaluation and evidence-based refinement are needed to improve the effectiveness of the law.
