Occurrence of ochratoxin A – producing fungi in raw Brazillian coffee.

OA – producing fungi were identified in coffee at different stages of maturation and OA was quantified in coffee during terrace drying and in coffee stored in barns. A high level of contamination (100%) was found in the coffee beans studied, with the genus Aspergillus representing 33.2% of isolates, of which Aspergillus ochraceus and Aspergillus niger represented 10.3 and 22.9%. respectively. Among 155 strains of A. ochraceus and A.niger, the capacity to produce ochratoxin was demonstrated in 88.1 and 11.5% of strains, respectively. Analysis for OA in the terrace and barn coffee samples showed that, independent of cultivar, year harvested or production region, all except one of the samples analysed showed OA levels below the limit suggested by the European Common Market.
