Mycotoxin determinations on animal feedstuffs and tissues in Western Canada.
Results of examination of specimens of plant or animal origin for various mycotoxins are presented. Analyses for aflatoxins and ochratoxins were most frequently requested, usually on the basis of visible mouldiness. Aflatoxin B1 was found in one of 100 specimens at a level of 50 ppb in a sample of alfalfa brome hay. Ochratoxin A was detected in seven of 95 specimens comprising six samples of wheat at levels between 30 and 6000 ppb and one sample of hay at a level of 30 ppb. An overall detection rate of 4.2% involving significant levels of potent mycotoxins suggests that acute or chronic mycotoxicoses may occur in farm livestock or poultry more frequently than presently diagnosied.
