Mind the gaps

A performance audit conducted by the U.S. Government Accountability Office between January and April shows that while the Food and Drug Administration has begun to take action to address weaknesses in food labeling and food safety research, gaps remain.

The G.A.O.’s task in conducting the audit was to examine ways in which the F.D.A. may use science to more effectively support its regulatory work and inform the public about food content and safety. As such, the report focused on three things: F.D.A.’s progress in addressing selected recommendations identified by the Science Board; incorporation of scientific and risk analysis into its oversight of the accuracy of food labeling, fresh produce, and the safety of dietary supplements; and a new computer screening tool that may improve its efforts to screen imports using a risk-based approach.

According to the G.A.O.’s findings, a lack of certain scientific information has hampered the F.D.A. in its ability to carry out some food safety responsibilities, including oversight of food labels, fresh produce and dietary supplements.

“For food labels, we found that F.D.A.’s research on their accuracy, consumers’ perceptions of them, and other labeling options was limited,” said Lisa Shames, director of natural resources and environment for the G.A.O., in a letter accompanying the G.A.O. report. “For fresh produce, we found that gaps in scientific knowledge have limited F.D.A.’s efforts to integrate science and risk analysis into its oversight. Finally, for dietary supplements, we found that F.D.A. lacked information to better identify safety concerns associated with dietary supplements.”

Inadequate labeling a concern

The G.A.O. report identified three areas in which the F.D.A.’s oversight has contributed to inadequate food labeling: accuracy of Nutrition Facts Panel information; misleading food labeling; and options for a front-of-package nutrition labeling system.

“F.D.A.’s research to determine the accuracy of nutrient information is limited and outdated and shows varying degrees of compliance,” Ms. Shames wrote. “F.D.A. has not conducted random sampling on food labeling since 1996.”

Ms. Shames noted that while the F.D.A. found most of the randomly selected products tested within allowable ranges, compliance rates varied for a few nutrients. While variances may contribute to impaired health, the F.D.A. said it has no plans for future studies, Ms. Shames said.

Misleading food labeling continues to be a problem because the F.D.A. does not have the empirical research on consumer perceptions to support enforcement against misleading food labels, Ms. Shames wrote.

The G.A.O. audit found more collaborative research is needed to help the F.D.A. sort out the options for a front-of-package nutrition labeling system. The G.A.O. has recommended that the F.D.A. collaborate with other federal agencies and stakeholders to evaluate options for a “simplified, empirically valid system that conveys overall nutritional quality and that mitigates labels that are misleading to consumers.” In addition, the G.A.O. recommended the F.D.A. maintain data on labeling violations and the corrective actions taken in a searchable format, analyze violation data in routine management reports, and track regulatory meetings on labeling violations to assess whether they are an effective use of resources.

In October 2009, the F.D.A. said it was in the process of developing a proposed regulation to define the nutritional criteria that would have to be met by food companies making front-of-package claims about a product’s nutritional quality. This past April, the agency sought comments about front-of-package labeling, specifically asking for data about the extent to which consumers notice, use and understand nutrition symbols on front-of-pack labeling of food packages or on shelf tags in retail stores; research that assesses and compares the effectiveness of particular approaches to front-of-pack labeling; graphic design, marketing and advertising data and information that can help develop better point-of-purchase nutrition information; and how point-of-purchase information may affect decisions by food manufacturers to reformulate products. The F.D.A. is accepting comments until July 28.
