The rules that dictate how companies must tell consumers when they are buying genetically engineered food are open for comment. The U.S. Department of Agriculture is seeking input on a proposed rule to create the National Bioengineered Food Disclosure Standard, which was passed by Congress in 2016. Comments are due by early July. The standard will provide a uniform way to offer meaningful disclosure for consumers who want more information about their food and avoid a patchwork system of state or private labels that could be confusing for consumers and would likely drive up food costs, the agency said in a news release.
