Using layers of irradiated but still fertile maize grain, the effects of water activity (aw) and temperature on interspecific interactions between Aspergillus ochraceus and five other spoilage fungi were examined. At 18ºC, ochratoxin production by A. ochraceus was inhibited significantly by A. candidus (0.995 and 0.95 aw) and A. niger (0.995 aw). When grown on maize grain at 30C, ochratoxin production by A. ochraceus was significantly inhibited by other spoilage fungi when both were grown on maize grain, especially by A. niger and Eurotium amstelodami at 0.995 aw and A. flavus at 0.95 aw.
