Fungal contamination of rice from south Vietnam, mycoloxinogenesis of selected strains and residues in rice.

Twenty-five samples of Vietnamese rice coming from the Mekong delta were analysed for fungal contamination. Aspergillus was the most important genus (43.75% of isolates) followed by Fusarium (21.8%) and Penicillium (10.9%). Isolated strains of Aspergillus flavus, A. ochraceus and Penicillium curinum were tested for their toxigenic potential on either YES liquid medium of on autoclaved rice. Eighty percent of A. flavus strains were able to produce cyclopiazonic acid and all strins of A. ochraceus synthesised OA. The P. citrinum isolate produced citrinin. Two rice samples were found to be contaminated with OA at 21.3 and 26.2 mg/kg.
