The U.S. Food and Drug Administration said it is having difficulty implementing expansive new rules to improve food safety, nearly two years after President Barack Obama signed them into law.

Reuters reports that FDA Commissioner Margaret Hamburg predicted yesterday that her agency “very soon” will issue new regulations needed to enforce the Food
Safety Modernization Act, a sweeping law enacted to upgrade the security of the U.S. food supply after a deadly salmonella outbreak in 2009.

Hamburg called on private industry to help finance the law’s provisions. The FDA regulates about 80 percent of the U.S. food supply. The Department of Agriculture oversees meat and poultry.
