Aj/atoxin, a contaminant produced by the fungi Aspergillus j/avus and Aspergillus parasiticus in severalrnagricultural commodities, is a known human liver carcinogen. Red pepper is widely consumed inrnEthiopia and this agricultural commodity is known to be susceptible to aj/atoxin contamination. In thisrnresearch, aj/atoxin contamination of whole and ground red pepper in relation with storage duration andrnquality grading and the magnitude of the contamination in grounded red pepper were studied. Samplesrnwere collected from farmers and wholesalers and Aj/atoxins were determined using HP Le. Whole redrnpepper samples stored for three months shows low aj/atoxin contamination compared to red pepperrnsamples stored for six months (p
