Influence of indigenous post-harvest handling practices on storage fungal contamination of common bean (Phaseolus vulgaris L.) in Cameroon

Common bean (Phaseolus vulgaris L.) represents a staple legume crop in many tropical and subtropical regions typically Cameroon, serving as a major source of protein, income, and food security for rural households. In Cameroon, Common bean is usually stored by most farmers after harvest as a source of food and for sale. From the stored bean, the surplus from that meant for food is sold by some small-holder farmers to earn income However, post-harvest losses due to storage fungi significantly compromise grain quality and safety. Traditional post-harvest practices; including manual harvesting, inadequate drying, and low-level storage structures create conditions favorable for fungal infection and proliferation. This review examines how prevailing indigenous post-harvest practices in Cameroon contribute to common bean infection by storage fungi. Evidence from studies carried out in Cameroon indicates that incidence of fungal infection increases substantially during storage and involves genera such as Aspergillus, Penicillium, Fusarium, and Xylaria spp. Poor drying, exposure to moisture and pests, and insufficient storage hygiene exacerbate these infections. Improved drying methods, sanitation, hermetic storage technologies, and farmer education are discussed as strategies to reduce fungal contamination and associated mycotoxin risks. The review underscores the need for targeted farmer education, accessible storage technologies, and contextualized extension services to reduce post-harvest fungal losses in common bean production systems. Strengthening post-harvest management practices is essential for reducing fungal contamination, improving food safety, and enhancing the overall value chain of common beans in Cameroon. It is paramount that effective common bean fungal management strategies be implemented by farmers.
