The use of hermetic storage for the protection of grain from aflatoxin accumulation has been tested multiple times, often with conflicting results. Williams et al. (2014) demonstrated the use of PICS bags for the storage of maize at 27 °C in laboratory conditions, showing that PICS bags mitigate the growth of A. flavus and the accumulation of aflatoxin during storage as well as maintaining the initial moisture content of the maize. Similar results were reported for the storage of shelled peanuts in hermetic bags at 30 °C (Navarro et al., 2012). However, Fusseini et al. (2016) found an increase in maize moisture content as well as aflatoxin levels during storage in triple-layer hermetic bags across multiple temperatures under laboratory conditions. Their results also indicated that cooler temperature (16 °C) resulted in the largest increase in aflatoxin accumulation. This conflicting evidence furthers the debate on the efficacy of hermetic storage for the mitigation of accumulation of aflatoxin. Under field conditions in Brazil and Kenya, the number of Aspergillus spp. increased during storage, even in hermetic storage systems (Di Domenico et al., 2016, Maina et al., 2016, Viebrantz et al., 2016). However, aflatoxin accumulation during these storage experiments did not provide conclusive evidence about the efficacy of the hermetic systems.
