title: [Use of the radioimmunologic determination of ochratoxin A mycotoxin in the screening of foods and animal feed of plant origin--cereal type].
abstract: Trials were conducted to verify a simple procedure of preparing food and feed samples of plant origin for the radioimmunological assay of ochratoxin A. All 27 food samples subjected to testing met the general hygienic regulations for foods (NPK - ochratoxin A 20 micrograms.kg-1), and so did all 23 samples of the tested feeds. The proposed method of sample preparation is not suitable for the examination of animal-origin foods because some proteins (albumin) might interfere.
