title: [Ochratoxin A: study of grain contamination].
abstract: Ochratoxin A was quantitatively monitored in grain extracts by indirect solid-phase enzyme immunoassay with the use of an immobilized conjugate of the toxin with gelatin and polyclonal rabbit antibodies raised against the ochratoxin A-BSA conjugate. This monitoring found that 1.7 to 18.5% of the samples were contaminated with the toxin at a concentration of 25.9-291.7 micrograms/kg. An analysis of forage grain found ochratoxin A at concentrations of 440-3250 micrograms/kg.
