To investigate the occurrence of potential ochratoxin A (OTA) producing moulds in foodstuffs, 11 food samples from the south-west part of France have been studied: 8 were contaminated with OTA (0.6 to 12.8 μg/kg). 120 filamentous fungi and 10 yeasts were isolated from these foodstuffs. Among the 30 genera isolated, the Mucedinacex (44%) were the most frequent, followed by Dematiaceæ (26%) and Ascomycetes (10%). 20 strains were potential producers of OTA: Penicillium aurantiogriseum(10 strains), P. chrysogenum(1 strain), P. variabile(6 strains) and Aspergillus ochraceus(3 strains). Only 8 of these strains produced OTA in vitrowhen cultured in liquid complex medium, indicating that they are rather adapted to solid phase. These findings are to be related to the OTA contamination of human blood in these areas and in other parts of France. |
