In January 2014, Walmart, the largest grocery retailer in the U.S., announced it was joining the Fair Food Program. In its agreement with the CIW, Walmart committed to help expand the Fair Food Program outside of Florida and into crops other than tomatoes. Alexandra Guáqueta, chair of the UN Working Group on Business and Human Rights, attended the signing ceremony and conveyed a statement on behalf of the Working Group. The statement praises the Fair Food Program for its "smart mix" of monitoring and enforcement tools, including "market incentives for growers and retailers, monitoring policies and, crucially, a robust and accessible mechanism to resolve complaints and provide remedy," adding, "Workers have no fear of retaliation if they identify problems." The statement concludes, "We are eager to see whether the Fair Food Program is able to leverage further change within participating businesses, and serve as a model elsewhere in the world."
