Ajlaloxin conlaminalion of lef! in Erhiopia lVas reporled in 1987, indicaling Ihal ill!;her probabililY of conI aminal ion of leff, sampled Fom differenl parI of Erhiopia. The objeclive oflhis sludy lVas 10 invesligale occurrence of lola I ajlaloxin in lef!prodllced by commercial farms of Elhiopia and Ihe ef!ecl of slored lemperallire and relalive humidilY lVas also invesligaled In addilion, KAP sllldy lVas also conducled on OlVners and employees of commercial farmers. A IOled of Eleven commercial lef! producing farms lVere randoml)! selecled and, Ajlaloxin B1, B2, C I and C2 were delermined al microgram per kilogram (JIg/kg) levels by immllno-ajjinily column clean lip and reversed-phase liquid chromatography lVilh fluo rescence defection. The result showed all of Ihem were below the maximllm (4 Ilg/kg) ,olerable level of Elhiopion lef! jlollr slandard The highesl AF concenlralion lVas 3.99 JIg/kg and Ihe 10IVesl concenlralions lVas 0.5 JIg/kg.

From Ihe samples analysec/, 13. 88%, 0%, 8.38% and 77.73% were conlaminaled lV ilh qllanlifiable concenlralions of ajlaloxin C2, C1, B2 and 81 respeclively.
