U.S. consumers see retail beef products with “no added hormones” (NAH) labels. However, similar labels appear on pork and chicken products, even though hormone use in their production is prohibited. This study assesses consumer perceptions of hormone use in different livestock species. Using choice experiment data, we then examine the impact of these perceptions on preferences for unlabeled meat products and willingness to pay for NAH-labeled meat products. Results suggest that consumer perceptions of hormone use in production are incorrect. Further, perceptions influence consumer preferences and willingness to pay for unlabeled products versus those with NAH labels.
