Analysis of post-harvest treatment practices for kola (Cola nitida) using the HACCP system in three cities of Côte d'Ivoire

The aim of this study is to propose a revised treatment scheme for fresh kola nuts (Cola nitida) using Hazard Analysis Critical Control Point (HACCP). Specifically, this will involve analysing the nut processing diagram used by the stakeholders, identifying critical points and proposing corrective measures for these critical points. A survey at kola producers and traders, coupled with an on-site diagnosis, was carried out in the cities of Anyama, Bouaké and Agboville. The verification of the preconditions was based on a checklist. In addition, the kola nut processing and storage system was evaluated according to the 12 steps of the HACCP system. The diagnosis of the sector revealed an informal organization and traditional practices. A revised diagram of the cola treatment process according to the HACCP system has been developed. This diagram includes three critical control points (CCPs) at the reception, sorting and biopesticide treatment level. A HACCP plan has been drafted to better monitor and control each critical point. The technical routes for processing cola do not guarantee good quality nuts. They do not comply with good hygiene practices (GHP) during the processing and storage process. The adoption and monitoring of the HACCP system would be beneficial for the kola industry.
