The aim of this study was to determine the amount and type of aflatoxinogenic fungi on samples of
pistachios collected from warehouses in Kermanshah, Iran. Overall, a total of 632 samples were randomly collected
and based on their physical properties the samples were categorized into following groups: (i) raw pistachio with
intact shells, (ii) raw pistachio with broken and damaged shells, (iii) salted pistachio with intact shell, and (iv) salted
pistachio with broken and damaged shell. Then 158 subsamples were chosen from each category. The overall
contamination rate was 66%. The fungus contamination rates were significantly lower in salted in compared to raw
samples (p<0.05). The percent contaminated samples recorded 45.6% and 33.3% in salted pistachio with intact shell
and salted pistachio with damaged shell, respectively. The most fungal contamination rate was recorded for
Aspergillus niger followed by Aspergillus flavus and Aspergillus terreus in all categories. The percent
contamination of samples by Aspergillus niger was significantly higher in raw samples in comparison to salted
samples. The salted pistachio with damaged shell was significantly lesser contaminated to Aspergillus niger when
compared with the salted pistachio with intact shell (p<0.05). The Penicilium spp. contamination rates were
significantly higher in damaged shell samples compared to intact shell samples and apparently this type of
contamination did not decrease in salt-treated samples while, the salted, intact shell samples have shown
significantly more Aspergillus flavus contamination rates than salted, damaged shell (p<0.05). The Aspergillus
terreus contamination rates were significantly higher in intact shell samples compared to damaged shell samples.
These toxigenic fungi isolated raises concerns on the potential of pistachio products as a natural substrate prone to
the mycotoxin formation.
