Compare this to what our friends in Washington are doing. The House of Representatives will vote on March 2 for a "national food uniformity" labeling law that will prevent states and localities from requiring labelling that specific foods or beverages are likely to cause cancer, birth defects, allergic reactions, or mercury poisoning. The bill would also prevent localities from requiring labelling on genetically engineered foods and ingredients.
