Abstract
Artisanal production of tapioca in Mbujimayi is an essential food activity but remains characterized by a strong variability in physicochemical and microbiological quality. Empirical processes, the absence of standardization norms, and the lack of hygiene training expose consumers to health risks, particularly related to the presence of pathogenic bacteria and molds. This study aims to evaluate the microbiological quality of locally produced artisanal tapioca and to propose improvement perspectives to ensure food safety. A cross-sectional descriptive survey was conducted between June and November 2024 among 36 Tapioca processors. Data were collected through questionnaires, interviews, and samples subjected to bacteriological analyses. A reasoned non-probabilistic sampling method was used to compare tapioca prepared by the researchers themselves (sweet and bitter cassava) with that purchased from local processors. Statistical analysis was performed using SPSS software. Results reveal that most processors respect the preparation steps and apply a 72-hour fermentation, but mainly use water from wells or rivers and have received no hygiene training. Microbiologically, tapioca prepared by the researchers showed a compliant lactic flora and remained free of major pathogens, although some opportunistic contaminations were observed. In contrast, tapioca purchased from local processors was heavily contaminated with enterococci, fecal coliforms, yeasts, molds, staphylococci, as well as Salmonella (44.4%) and Escherichia coli (100%), indicating a high health risk. In conclusion, the quality of artisanal tapioca depends on the control of critical processing steps. Improvement requires hygiene training for processors, the use of treated water, standardization of procedures, and the establishment of simple community-based controls. These measures would reconcile traditional know-how with modern sanitary requirements, making artisanal tapioca from Mbujimayi safer and more competitive.
