Investigation of mycotoxin Patulin in some types of dried fruits in Baghdad governorate

The results of mycotoxin Patulin ( PAT ) detection in 21 samples of dried fruits (grape and apricot) collected from different locations at Baghdad governarate and one sample from Karbala province revealed that all tested samples were contaminated with PAT ,samples K , D and C which collected from Karbala , Al-shoala and Palestine Street showed the highest contamination levels which recorded (30499.5, 2836.3 and 1795.3) µg/ml , while the samples I, S and G which collected from Al- Harthiya , Al- Sadr City and Al- Harthiya (2) showed the lowest contamination level which recorded (7.8 , 11.7 and 19.8) µg/ml. The results also showed that Aspergillus spp. recorded the high percentage of occurancy 100% in H sample and in samples (N , K , U , A , J) the percentage of occurancy is (94.12 , 94.44 , 95.45 , 95.56 , 96.55)% respectively. Also the percentage of Penicillium spp. occurancy rated from 0.0 to 46.15% , sample (H) recorded the lowest percentage of occurancy 0.0% while sample (M) recorded the highest percentage 46.15% . The results of toxigenic ability of 5 isolates include A.flavus and A.fumigatus and 3 isolates of P.expansum from three different samples include K , S and Z. Regarding A.flavus and A.fumigatus were not produced PAT, while P.expansum isolate from S and Z recorded the ability to produced PAT after 5 days , while P.expansum isolated from K produced PAT after 15 days. The highest ability to produce PAT recorded in S 16.5 µg/ml, and the lowest ability in K 13 µg/ml.
