The occurrence of deoxynivalenol in Norwegian cereals : differences between years and districts, 1988 –1996.

The amount of DON was determined in about 5000 samples of barley, oats and wheat grown in Norway from 1988 through 1996. Of all samples analysed, 68.9% contained DON concentrations exceeding 30 mg/kg; 61.3% of the barley, 81.4% of the oats and 61.5% of the wheat samples. The percentages of barley, oats and wheat samples containing 1,000 mg/kg or more were 6.6, 12.5 and 3.1, respectively. Oats produced in commercial fields were found to be significantly more contaminated with DON than barley and wheat. A strong positive correlation was found between the mean DON content and the amount of precipitation in July. In the most northern grain growing area in Norway, oats generally were more exposed to DON contamination than oats from the rest of the country, while the opposite seemed to be the case for barley.
