Ochratoxins are fungal secondary metabolites that contaminate grains, legumes, coffee, dried fruits, beer, wine, and meat. Ochratoxins are considered powerful nephrotoxins, carcinogens, teratogens, and immunotoxins in rats and likely in humans. In 2006 during a pilot program of Hazard Analysis Critical Control Point in the Apulian region, Southern Italy, ochratoxin A (OA) was detected in commercial feed for laying hens in 2 farms. The OA-contaminated feed had been administered to animals for at least 2 mo. Analysis by HPLC with fluorometric detection of the tissues of 4 layer hens that displayed gross and microscopical lesions identified OA in the kidney (8.7 to 16.9 g/kg, average 13.65 ± 3.58 g/kg) and liver (3.7 to 5.1 g/kg, average 4.43 ± 0.64 g/kg) but not in the other tissues.

Abstract
Ochratoxins are fungal secondary metabolites that contaminate grains, legumes, coffee, dried fruits, beer, wine, and meat. Ochratoxins are considered powerful nephrotoxins, carcinogens, teratogens, and immunotoxins in rats and likely in humans. In 2006 during a pilot program of Hazard Analysis Critical Control Point in the Apulian region, Southern Italy, ochratoxin A (OA) was detected in commercial feed for laying hens in 2 farms. The OA-contaminated feed had been administered to animals for at least 2 mo. Analysis by HPLC with fluorometric detection of the tissues of 4 layer hens that displayed gross and microscopical lesions identified OA in the kidney (8.7 to 16.9 g/kg, average 13.65 ± 3.58 g/kg) and liver (3.7 to 5.1 g/kg, average 4.43 ± 0.64 g/kg) but not in the other tissues.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
