The effects of consumer perceptions on attitudes toward the United States Food and Drug Administration (FDA)'s current labeling policy for GM foods are examined.  Results show that as beliefs regarding potential adverse effects of GM crops on wildlife and the environment increase, consumers are less likely to support the FDA's current labeling policy.  The perceived safety of GM foods was also found to be important.  As consumer perceive GM foods to be safe (unsafe), they are more (less) likely to support the current policy.  However, concerns regarding potential environmental damage of GM crops are more important relative to beliefs regarding the potential for negative long-term health effects.
