In this article，information attributes of traceable pork with pre-incident quality assurance and post-incident traceability were established. Firstly，consumer preferences for information attributes regarding pre-incident quality assurance and post-incident traceability，as well as the interrelationships between these attributes，were investigated for 604 consumers in Wuxi City，Jiangsu Province，China based on the MVP model，using sequential elicitation，which combined a Becker-DeGroot-Marschak（BDM）auction and menu-based choice experiment. The results suggest that attribute price was an important factor in consumer choice of supply chain traceability. Furthermore，under budgetary constraints，substitute or complementary relationships between attributes were identified，out of which pork quality inspection and supply chain + internal traceability were the two attributes most preferred by consumers for pre-incident quality assurance and post-incident traceability，respectively. Therefore，establishing information attributes should cover all risk processes throughout the pork supply chain to provide traceable pork with multi-level information attributes to the market. Moreover，traceable pork with quality inspection that allows pre-incident quality assurance should be provided to the market by customization. Such efforts will positively contribute to the development of a traceable pork market system in China.
