• Dry fruits
• Edible nuts
• HPLC

A total 307 samples of dry fruits and edible nuts from Northern areas and Khyber Pakhtunkhwa, Pakistan were evaluated for the presence of aflatoxins (AFs). The samples were analysed using a reversed phase HPLC, equipped with fluorescence detector. Results have revealed that 132 out of 307 samples of dry fruits and nuts were found positive with aflatoxin B-1(AFB(1)) and total AFs. The highest mean level of total AFs i.e. 7.89 +/- 0.99 mu g/kg was found in peanuts without shell and lowest mean level (2.45 +/- 0.11 mu g/kg) was found in watermelon seeds without shell samples. Samples 75 (24%) were found contaminated with AFB(1), ranged from 8 to 10 mu g/kg and 41(13%) samples were found above the level of 10 mu g/kg for total AFs. The high occurrence of AFs may cause health hazards for consumers and limit exports.
