Connecticut on [June 3] became the first state to pass a bill that would require food manufacturers to label products that contain genetically modified ingredients. Gov. Dannel P. Malloy has said he would sign the bill into law, after reaching an agreement with the legislature to include a provision that the law would not take effect unless four other states, at least one of which shares a border with Connecticut, passed similar regulations. This bill strikes an important balance by ensuring the consumers' right to know what is in their food while shielding our small businesses from liability that could leave them at a competitive disadvantage," Mr. Malloy said in a statement issued over the weekend after negotiations on the necessary provisions. The legislature passed the bill on Monday, 134 to 3. More than 20 other states are considering labeling laws, including New York, Maine and Vermont. Early polling suggests widespread support for a ballot initiative that would require labeling in Washington, as concern spread about the impact of genetically engineered salmon and apples on two of the state's marquee businesses. In 2005, Alaska passed a law requiring the labeling of all genetically engineered fish and shellfish, but Connecticut would become the first state to adopt labeling broadly. Andrew Kimbrell, executive director of the Center for Food Safety, called Connecticut's move an "important first step," and "a reminder of where the tide is going on this issue." Big food and seed companies like Monsanto and Dow spent tens of millions of dollars last fall to help defeat a ballot measure in California that would have required labeling.
