Knowledge, Hygienic Practices, and Toxi-Infectious Risks Associated with Ready-to-Eat Gbeli: A Particular Chip Derived from Cassava (Manihot esculenta Crantz) Tuber Vended in Streets of Abomey-Calavi Municipality, Benin.

Abstract

The lack of regulations relating to street food remains a real problem in most developing countries. To remedy this, it is essential to have reliable data on the actors and the conditions of streed food activity. The present study is aimed at (i) establishing the sociodemographic profile of producers and vendors of Gbeli in the municipality of Abomey-Calavi, (ii) developing the technical production diagram and assessing the adoption level of good hygienic practices during the production and sale of Gbeli, and finally, (iv) evaluating the microbiological contamination risks associated with Gbeli consumption. Direct observations followed by a semistructured survey on 92 Gbeli vendors were carried out in Abomey-Calavi municipality. A Gbeli sample was collected from each vendor for microbiological analyses according to standard microbiology analytical techniques. Forty vendors were assisted during Gbeli production. The results showed that the production and sale of Gbeli are activities carried out solely by women (100%), mostly adults (97.82%) and unschooled (58.69%). This trade generates income allowing the vendors to contribute to their household expenses and to save. No major difference was noted in the production process of Gbeli contrary to the sale modes (stationary, itinerant, and mixed). Production process, packaging form, and sale condition of Gbeli present enormous hygienic practice deficiencies. Some corrective measures were thus suggested. About 56% of Gbeli samples analyzed were microbiologically not up to standard. The prevalence and abundance of mycotoxinogenic molds, thermotolerant coliforms, and coagulase-positive Staphylococci in these chips are very worrying. The consumption of Gbeli therefore exposes its consumers to a permanent risk of food poisoning. Training of Gbeli vendors on good hygiene and production practices is indispensable.
