Consumer reactions to the use of EU quality labels on food products: A review of the literature

The EU promotes three types of food quality labels, PDO, PGI and TSG in order to protect producers of food with special qualities and to aid consumers in their decision-making. This papers reviews published research on how these labels affect consumers. 35 studies were identified and are reviewed based on a hierarchy of effects framework. While results are conflicting, some overall themes emerge, suggesting that the role of these quality labels in consumer decision-making at present is still relatively low. Suggestions for research are made that would provide a better basis for evidence-based policy formulation with regard to food quality labels.
