Republicans and Democrats on the U.S. Senate Agriculture Committee have struck a deal that would create the first nationwide standard for foods containing genetically modified organisms. Under the agreement, consumers may still have difficulty figuring out if the food they are buying is genetically modified because it wouldn’t mandate printing “GMO” on the exterior. Instead, the agreement would offer three options for disclosure: text on the packaging, a symbol, or an electronic link that would direct consumers to a website for more information.
