Two different ways of finishing maize, one intensive (industrial) and one extensive, were compared to establish what postharvest losses occur and how great the losses are, as well as to determine the quality and hygiene status of maize as a raw material for industrial uses, i.e. processing either into animal feed or human food. Data show that the damage suffered in the silo-bin can be mechanical or thermal. Intensive maize kernel thermal treatment increases postharvest losses. This problem could be eliminated by harvesting maize with a moisture content below 30% and by applying multiple stage drying, which in turn increases the cost of finishing. Although drying and mechanical transport cause considerable physical kernel damage, the stored maize remains satisfactory in a sanitary sense for more than 8 months, i.e. it is stable from a microbiological point of view and is suitable for further processing. Sources of kernel damage in maize cribs are the long-term drying process required for maize on

 the cob, the immovable mass, and poor crib aeration, i.e. faulty crib location. As regards sanitary status (especially microbiological aspects), maize can only be safely stored for 6 months if there is a severe winter with low temperatures.
