Sixty-four countries around the world, including Australia, Japan, and all of the countries in the European Union, require genetically modified foods to be labeled. Canada does not require any GMO labeling.
GMOs are not currently labeled in the United States. However, the National Bioengineered Food Disclosure Standard (NBFDS) was published in the Federal Register on December 21, 2018. This law, which you may have heard called the DARK Act, is the start of mandatory GMO labeling in the United States. It means that some—but not all—products containing GMOs will have to be labeled by 2022. In its current form, categorical exemptions prevent this law from delivering the meaningful protections Americans deserve.
