Abstract: | To detect ochratoxin in grains and some feed mixtures the method described by Nesheim et al. (1973) was chosen out of a large number of analytical procedures. No ochratoxin was assayed in any of 41 samples (barley, corn, wheat, oats, complete feed mixtures, degraded straw) which were obtained from the current operation of feed-processing plants, did not contain any macroscopically detectable molds, were taken from storehouses with safe store conditions and they were evaluated by agricultural enterprises as safe. This method can be recommended to assay grains for ochratoxin in Czechoslovakia. |
