Mapping the Pork Value Chain in Vietnam: a Systematic Review

In Vietnam, pork is the most commonly consumed type of meat, and the demand is expected to rise even further. Nevertheless, food safety is a major concern, as the country bears a high burden of food-borne diseases, including these caused by pork products. Knowledge of the flows of pigs and pork from producers up to the consumers is important; however, up to now, a comprehensive overview is lacking. We addressed this by conducting a systematic review on the pork value chain (PVC) mapping for the country. Four international and three Vietnamese databases were searched for data on the pork value chain in Vietnam, and the results were reported according to the PRISMA guidelines. Data obtained from the retained records showed that 10 main PVC types are present in Vietnam, comprising of five main actors including: producers, middlemen, slaughter men, retailers and consumers. Among the identified chains, the one involving producers, slaughter men, retailers and consumers is the most common one, with up to 75% of pork following this route. In cities or export routes to other countries, middlemen and/or traders are important additional actors in the PVCs. The small scale of PVC linkages is prominent. The presence of middlemen, pig traders and pork traders is contributing to further distribution of pork products in geographical terms. Transactions between actors in the traditional PVCs in Vietnam are characterized by the absence of official contracts; therefore, the linkages in the chains are loose and the origin of pork is not traceable. More industrial forms of PVCs are slowly developing; however, the traditional PVCs are still prevailing in Vietnam. The weak linkages between actors and poor hygienic practices in these chains form a risk to pork safety.
