Abstract

Altogether 360 samples of Chilli, maize and groundnut (120 from each commodity) were collected from Kathmandu Valley in four different seasons from April 2007 to January 2008, for the determination of Aflatoxin B1­ (AFB1). TLC Method was used for estimation of AFB1). Out of 360 samples, 88 (26 chilli, 30 maize and 32 groundnut) samples were found to be contaminated with AFB1 at the level of more than 10 µg/kg and average concentration of  AFB1  in three commodities was found to be 50.8 µg/kg. Among the contaminated samples, chilli showed least amount of AFB1 i.e. 34.87 µg/kg on average; maize showed 50.17 µg/kg and ground nut showed the highest amount i.e.64.23 µg/kg of AFB1 contamination. Among the  analyzed samples, 14 chilli, 18 maize and 24 ground nut were found to be contaminated with the AFB1 at more than 20 µg/kg (i.e. recommended maximum permissible level in Nepal) .Based on the seasonal variations, maximum number (26) and maximum amount (64.99 µg/kg) of contamination was found in April and January respectively among three commodities.
