title: A survey of cereals, cereal products, feedstuffs and porcine kidneys for ochratoxin A by radioimmunoassay.
abstract: A commercial kit for the radioimmunochemical determination of ochratoxin A has been validated for application to various foods and feedstuffs. Using this kit a survey was carried out for the occurrence of ochratoxin A in Czechoslovak cereals, cereal products, feedstuffs and pig kidneys. The results show that the most contaminated are feedstuffs and cereals, in 26.7% and 8.8% of the samples of which, respectively, the ochratoxin A level exceeded 20 micrograms/kg. None of the cereal products and 4.2% of the pig kidneys unfit for human consumption by visual examination possessed ochratoxin A concentration higher than 5 micrograms/kg. Of all the samples analysed, 57% contained no detectable toxin (less than 1 microgram/kg).
