Front cover: In southern Nigeria, farmers may store dehusked maize on the floor in a room of the house. This storage method was associated with high levels of alfatoxins.

Small scale farmers across sub-saharan Africa cultivate as much maize as they can physically work by hand. Crop husbandry practices which reduce stress to the maize as it develops help lower the amount of pre-harvest contamination with mycotoxins.

In the northern Nigeria, maize is dried in the field. Research has shown that the more time maize is left in the field after maturity, the greater is the risk of significant contamination with mycotoxins.

In the northern Nigeria, maize grain is separated from husk and cob in the field by the women hired to thresh, and then it is stored as loose grain in bags. The procedures used to move the crop from field to storage vary widely from region to region. Processes which clean the maize before storage tend to reduce subsequent mycotoxin build up in storage.
