Stakeholders’ practices in the pork value chain: Potential risks for Taenia solium and Toxoplasma gondii transmission in Burundi

Abstract

Pork is one of the most consumed meats in the world, including in Burundi. This study aimed to describe the pork value chain (PVC), stakeholders’ practices, and the implications for the transmission of T. solium and T. gondii in Burundi. A mixed methods approach was used to collect data from stakeholders along the PVC in Bujumbura city, Kayanza, and Ngozi provinces, including literature reviews and food safety regulations. A total of 386 participants took part in the interviews and 63 participated in FGDs and informal conversations. The five types of PVCs were identified. Extensive pig production farms were predominant (81 %) with one to three pigs per pig keeper. Potential risks for porcine cysticercosis and toxoplasmosis in the primary sector included unfit pen conditions, misuse of latrines, open defecation, pigs fed mainly with grasses and leftovers, unsafe water, and human stool for crop fertilization. Home and clandestine slaughters were common for pigs infected with T. solium cysts. Most slaughter slabs did not meet slaughter and carcass transport standards or meat inspection regulations. There was a lack of refrigeration equipment for pork, as well as inadequate pork handling and preparation at retail outlets and homes. Following the HACCP principles, effective ways to mitigate hazards before reaching consumers were identified. This study revealed inadequate practices and their implications for the transmission of T. solium and T. gondii infections in Burundi. Urgent actions targeting the strengthening capacities and multi-sectoral collaboration, raising awareness, and changing practices are essential to control these parasites.
