Aspergillus strains were isolated from green coffee beans of different origin, and their ochratoxin producing ability was examined. The most prevalent species found in most samples was A. niger; some isolates of this species produced ochratoxins A and B. A. ochraceus strains were also isolated, some of which produced ochratoxins. The other Aspergillus species found in green coffee beans include A. flavus, A. fumigatus, A. tamarii, A. oryzae and A. parasiticus, none of which produced ochratoxins. Our results indicate that A. ochraceus is not the only Aspergillus species responsible for ochratoxin contamination of green coffee beans.
