Update: Current Legal Developments in Mandatory GMO Labeling  


Sponsored by the Agricultural and Food Law Consortium


Within the past decade, ballot initiatives and legislative proposals addressing the labeling of “Genetically Modified Organisms,” commonly known as “GMOs,” have been proposed in several states across the country, as well as on the federal level.  Primarily, the issue addressed is whether or not food products made with GMOs should be labeled as such.

The program will provide background to help the listener frame the discussion as well as an update of the current status of those proposals.  In addition, the program will address:

  • The historical development of GMO labeling debate;
  • A review the states’ laws that have been enacted;
  • The status of litigation involving the Vermont GMO labeling law;
  • Applicable ballot measures that voters have considered recently;
  • Federal legislation; and
  • An update on the AMS Process Verified Program
