Aspergillus species and mycotoxins in figs from California orchards.

In Californian orchards, figs naturally infected with A. alliaceus, A. melleus, A. ochraceus and A. sclerotiorum contained ochratoxin at up to 9,600m/kg.  High levels of aflatoxin (>100m/kg) were detected in 83% of the figs infected by A. flavus.  Aflatoxins were not detected in figs infected with A. tamarii.  Of fungi isolated from fig orchard soils, A. parasiticus isolates always produced aflatoxin but never cyclopiazonic acid, while A. flavus strain S (producers of small sclerotia) isolates always produced both aflatoxin acid and cyclopiazonic acid, but strain L (producers of large sclerotia) isolates frequently did not produce aflatoxin or cyclopiazonic acid.  A tamarii isolates never produced aflatoxin but always produced cyclopiazonic acid.
