In order to establish their ability to produce the ochratoxin A (OCTA), seven species and three varieties of Aspergillus section Nigri were examined using malt-yeast extract agar (MYA) and rice cultures at 25 °C for 21 days. MYA cultures and moldy rice were extracted with CHCl3, and OCTA in the extracts was confirmed by HPLC and TLC. Only one strain of Aspergillus carbonarius was positive for OCTA. The levels of OCTA produced were 6.78 µg per ml of MYA and 0.4 µg per g of rice, respectively. This is first report of production of OCTA by Aspergillus carbonarius.
