In this study, we adopt the Grounded Theory to encode the consumers’ bad reviews of online shopping food in three levels and systematically identify the safety risks from supply chain. Thereafter, the quantitative Borda Count method was used to evaluate the severity of the eight sub-risks. The results showed that the safety risks of the online shopping food include four kinds of core risks containing eight kinds of sub-risks. The most serious risk was the lackness or insufficient of supervision in the e-commerce sales link and the insufficient specialization of logistics and transportation services in the logistics and transportation link. The second most severe risk was quality risk of raw and auxiliary food materials in the processing link, asymmetric information in e-commerce sales link as well as unqualified storage and transportation conditions in the logistics and transportation link, etc. To ensure food safety in online shopping, e-commerce platforms should increase the punishment on speculative enterprises, and logistics companies should implement different standardized management for food transportation. Moreover,food companies should pay more attention to the quality of the raw and auxiliary food materials.
