Abstract: The methods of cowpea storage using biopesticides, without risk to human health and the environment, could be an alternative in the fight against pests. The leaves of savanna tea (Lippia multiflora Moldenke) were tested for their antifungal properties, anti-pest infestations on stocks of cereals and legumes. Thus, the evolution of aflatoxins (B1, B2, G1 and G2) during the storage of cowpea (Vigna unguiculata L Walp) in PICS bags containing a biopesticide was studied. The risk of exposure associated with the consumption of cowpea was also studied. The results show the presence of total aflatoxins in 29.41 % of the samples, with 8.82 % of aflatoxin B1 at levels above the reference values. PICS bags ensure a longer shelf as control polypropylene bags. Adding Lipppia multiflora makes this even more effective conservation and allows the preservation of the health quality of cowpea to 8 months. The risk of aflatoxin exposure is lower when cowpeas stored in PICS bags with biopesticide that when stored in PICS bags without biopesticide or polypropylene bags.
