“…The combination of plants and the triple bagging system would reduce the metabolism of insects and molds thanks to the reduction of oxygen (O2) and the insecticidal and fungicidal activity of plants [29]; [30]. These results are in agreement with those of [31] who also observed a small change in OTA concentrations in cowpea stored in triple bags with the addition of L. multiflora in different proportions after eight months. The results of our study are equally agreement with the work of [16].…”

“…For the prevention of fungal development, the corn grains must have an Aw lower than 0.65 being the accepted limit value [32]. In addition, authors have shown the correlation between the evolution of Aw and mycotoxins (OTA, FB1, ZEA) in studies on the storage of corn in granaries in the presence of L. multiflora and H. suaveolens [33] and storing cowpeas in bags with triple bagging in the presence of L. multiflora [31]. The mycotoxins contamination observed in this study was revealed in previous studies in Côte d'Ivoire [10]; [11].…”

In Côte d’Ivoire, maize is second cereal most cultivated and consumed after rice. In bad storage conditions, corn may be contaminated by mycotoxins (aflatoxin B1, total aflatoxins, ochratoxin A, fuminosin B1, zearalenone). The aim of this study was to assess the exposure risk of these mycotoxins for maize stored in triple bags in presence of aromatic plants leaves (Lippia multiflora and Hyptis suaveolens). The contents of water activity, aflatoxin B1 (AFB1), total aflatoxins (AFT), ochratoxin A (OTA), fuminosin B1 (FB1) and zearalenone (ZEA) were studied and monitored. The levels of AFB1, AFT, OTA, FB1 and ZEA resulted from maize grains treated with plants leaves were significantly lower than those recorded with untreated maize of control bags. The estimated daily intakes in AFB1, AFT, OTA, FB1 and ZEA, deriving with consumption of maize from experimental batches stored for 18 months are respectively 1.69 ± 0.00 - 2.09 ± 0.01 ng/kg bw/day, 8.66 – 10.91 ng/kg bw/day, 1.86 ± 0.01 - 2.47 ± 0.01 ng/kg bw/day, 2.01 ± 0.05 - 3.01± 0.05 ng/kg bw/day and 1.89 ± 0.12 - 3.56 ± 0.04 ng/kg bw/day. These levels are lower than the estimated intakes from maximal reference value (EDILM) for OTA, FB1 and ZEA. For aflatoxin B1 and total aflatoxins, the estimated daily intakes are lower than the estimated intakes from maximal reference value (EDILM) during, respectively, 15 storage months and 10 storage months. However, after 18 storage months, exposure risk of aflatoxin B1 is higher than the estimated intakes from maximal reference value. This inexpensive and easy-to-use treatment should be popularized among farmers
