title: Mycotoxic porcine nephropathy and spontaneous occurrence of ochratoxin A residues in kidneys and blood of Polish swine.
abstract: Kidneys showing renal changes characteristic for mycotoxic porcine nephropathy were collected during the period 1 April 1982 to 31 March 1983 from 225,000 swine processed in a large slaughterhouse in the district of Poznań, Poland. Of 113 kidneys suspected of mycotoxic porcine nephropathy, 27 exhibited ochratoxin A levels from traces to 23 ng/g. In 17 kidneys the level of the toxin was lower than 2 ng/g. Increased frequency of ochratoxin A presence and its level in kidneys were observed during the spring. Of 195 porcine blood samples collected at random, 36 exhibited toxin levels from 3 to 270 ng/ml.
