Abstract:

Aflatoxins and ochratoxin A are mycotoxins produced by fungi belonging to the Aspergillus and Penicillium genera. The present study was carried out to study the natural occurrence of aflatoxins (AFS) and ochratoxinA (OA) in 90 nut samples collected from Tripoli, Libya during 2013 were determined by using a high-performance liquid chromatography technique. Aflatoxins B1, B2, G1 and G2, in the local market in Tripoli Libya during summer, 2013. Natural occurrence of aflatoxin B1, B2, G1 and G2 in almonds, Br. almonds, hazelnuts, cashews, walnuts and peanuts samples collected from local market in Tripoli. The percentages of positive samples with aflatoxins were 33.3, 40.0, 20.0, 13.3, 26.6 and 53.3% for almonds, Brazilian almonds, hazelunts, cashews, walnuts and peanuts, respectively. The concentrations of aflatoxin B1 were ranged between (0.9-5.3, 1.4- 7.8, 1.2 -5.4, 2.1- 3.4, 1.6-7.8 and 2.4-10.9 µg/kg) for almonds, Brazilian almonds, hazelunts, cashews, walnuts and peanuts, respectively. Aflatoxin B2 were found in Brazilian almonds ranged from (2.2-3.5 µg/kg) and in peanut (7.6-8.4 µg/kg). These results indicate the contamination of nuts with aflatoxins B1 and B2 were in various concentrations, this difference depends on type of nuts and environmental conditions, as well as the availability of nutrients to the fungus. The percentages of nut samples (almonds, Brazilian almonds , hazelunts, cashews, walnuts and peanuts) were contaminated with ochratoxin A 26.6, 33.3,  13.3, 20.0, 13.3 and 33.3%, respectively, also the concentrations  were ranged between (3.5-5.0,1.5- 2.2, 1.2 -3.7, 1.3- 2.5, and 4.0-6.5 µg/kg) for Brazilian almonds, hazelunts, cashews, walnuts and peanuts, respectively. However almonds free of ochratoxin A. The highest concentration found in peanut samples (6.5 µg/kg). The difference concentration of AFS or OA may be depends on type of nuts and environmental conditions, as well as the availability of nutrients to the fungus.
