  ABSTRACT
  Ocratoxin (OTA) occurs naturally in different foodstuffs, including grapes and their derivatives. OTA is a secondary fungal metabolite produced naturally by Aspergillus and Penicillium species. The purpose of this work was to estimate the occurrence of OTA in wine produced in Sicily to obtain a risk assessment of these substances. A total of 470 wine samples were quantitatively analysed by screening analysis method based on immunoenzymatic assay (ELISA) for ochratoxin. Results confirmed the presence of contamination by OTA in only one sample of red wine “Nero D’Avola” from south-oriental Sicily.
