Dozens of states are working on legislation that would require labeling of food containing Genetically Modified Organisms (GMO). Groups like Food and Water Watch are working to make such a labeling law a reality. The risks of GMO foods are unclear, in large part because the research so far conducted has been inadequate in scope, duration, and independence, because the vast majority of the research has been conducted or funded by companies selling GMO crops. These companies use their patent rights to limit independent research on their products. Please take action by signing the Food and Water Watch petition demanding labeling of GMO foods in Pennsylvania.
