Mycotoxins in grain for animal feeds.
A total of 302 crushed grain samples of barley, wheat, rye, corn and oats from the crop year 1974 were collected from commercial feed processing plants situated in all the provinces (voivodeships) of Poland. For the mycotoxin survey, performed according to the multimycotoxin detection method by Stoloff et al (1971), 150 grain samples were taken. The positive samples were analysed thereafter by the procedures for the individual mycotoxins and chemical confirmatory tests. Of the 150 samples tested by the multimycotoxin detection method, 77 (51 p. 100) showed fluorescing spots and Rf values of aflatoxins, 24 (16 p. 100) were of ochratoxins, 11 (7 p. 100) of zearalenone and 5 (3 p. 100) of sterigmatocystin. However when these samples were assayed by the specific methods and confirmatory procedures, only 8 (5 p. 100) samples were found to be positive, containing ochratoxin A at the level ranging from 50 to 200 microgram/kg.
