Summary:-One hundred samples of poultry meat products were collected fromdifferent supermarkets at Kalyobia and Cairo governorates and examinedfor detection of mould, yeast contamination as well as aflatoxins productfrom Aspergillus flavus species isolated from the same samples.In chicken burger the percentages of contamination with mould andyeasts were 650/0 and 100%, with mean values of 1.30 x 104± 0.6 x 104and 5.38 x 104± 1.17x104, respectively. The mould genera isolated fromchicken burger were Aspergillu (which further identified into A. niger, A.ochraceus and A. flavus), Pencillium, Mucor, Scopuloropsis,Cladosporium, Geotrichum, Fusarium and Alternaria. While the yeastgenera isolated were candida, Rhodotorula, Saccharomyces andTrichosporon. All the isolated strains of Aspergillus flavus from chickenminced meat could produce aflatoxine BJ,B2,G] andG2 in Yeast ExtractSucrose media (YES).In chicken frankfurter, the percentage of contamination with mouldand yeasts were 1000/0 (of each) with a mean values of 5.96 x 103±3.08x103and 1.16 x 105 ± 0.46x105 respectively. The mould generaisolated from chicken frankfurter were Aspergillus (which furtheridentified into A. niger, A. ochraceus, A. flavus, A. fumigatus and A.candidus), Penicillium, Cladosporium, Geotrichum, Fusarium andAlternaria. While, the yeast genera isolated were Candida, Rhodotorula,Saccharomyces, Trichosoporom and Debaromyces.. All the isolatestrains of Aspergillus flavus from chicken minced meat could producedaflatoxine B],B2,G] andG2 in Yeast Extract Sucrose media (YES).
