Abstract
Contamination with ochratoxin A and citrinin, penicillic acid and sterigmatocystin was observed in modly cereal grain samples (wheat, rye and barley), during 1975-1978. Levels of cereal grain contamination in various years were different. Usually 2 mo. after harvest percentage of contaminated samples was 5-7% and ochratoxin A content < 140 .mu.g/kg. During storage of grain with high moisture content, a slow increase of contamination level was observed during Jan. and Feb., to 1-3 mg/kg. Cereal grain from commercial channels was contaminated with fungi spores up to 109 spores/g. Aspergillus and Penicillium were predominating species. Between 69 fungi isolates typical for barley kernels, 13 were producers of ochratoxin, sterigmatocystin, penicillic acid and F-2 toxin. Results for wheat and rye will be published later.
