    Abstract:
    The mycotoxin ochratoxin A (OTA) is known to be the main contaminant of cereal grain and has become increasingly important in recent years. Therefore, a survey of ochratoxigenic fungi and OTA contamination in China is a special challenge. This paper summarises data on cereals and moulds (Aspergillus niger, Penicillium verrucosum, Aspergillus ochraceus, for example) and on grain and OTA from 1973 by searching Chinese information databases (NCKI, VIP, DuXiu etc.), calculating the OTA-producing mould detection rate, referring to sampling locations, latitude and temperature, and also combining six grain-producing areas of ochratoxigenic fungi and OTA positive rate through a comprehensive analysis. It is concluded that in China rice (excluding shell rice) has less OTA contamination than wheat or maize. The contamination of cereal grains with Aspergillus section Nigri (formerly of the A. niger group) is a serious problem in China, and these fungi may be the main ochratoxigenic fungi on cereals.
