Organic food and farm groups ask Obama to require GMO food labels

Four U.S. lawmakers joined with more than 200 food companies, organic farming groups, health and environment organizations and other groups on Thursday to urge President Barack Obama to require manufacturers to label food products that contain genetically engineered ingredients. The groups delivered a letter to the president dated January 16 reminding Obama of a campaign pledge the groups said he made in 2007 as he campaigned in Iowa to work to label so-called GMO foods. The issue is hotly contested, with more than 20 states considering laws to mandate labeling of foods made with gene-altered corn, soybeans, sugar beets and other biotech crops. Advocates of labeling say consumers deserve to know if the food they eat contains GMOs.
