Abstract

Ochratoxin A is a common contaminant in Danish cereals, and surveillance of ochratoxin A in cereals has been a part of the Danish monitoring system since 1986. Occurrence of ochratoxin A is highly related to the climatic conditions during harvest. Rye is the crop which is most often contaminated and contains the highest levels of ochratoxin A. The result of the survey period from 1986 to 1992 (total of 1431 samples) together with food consumption data is the basis of intake calculations. Especially in years with wet weather during harvest, the daily intake of ochratoxin A for some individuals in the Danish population could reach levels which exceed the tolerable daily intake (TDI) for ochratoxin A of 5 ng/kg bw suggested by The Nordic Working Group on Food Toxicology and Risk Evaluation. A maximum limit of 5 mu g ochratoxin A per kg cereal would keep the daily intake below 5 ng/kg bw.
