Mycoflora And Natural Occurrence Of Mycotoxins Of Chicken Stock

Abstract

Twenty four species and one species variety (belonging to 11 genera) and 20 species with the addition of two species varieties (belonging to 7 genera) were isolated on glucose-Czapek's agar and glucose-Czapek's agar medium fortified by 10% sodium chloride respectively, from 45 samples of manufactured chicken stock collected from Egypt. Aspergillus (10 species), Eurotium (6 species) Penicillium (6 species) and Emericella (one species) were the most common genera isolated from the two different media. Thin layer chromatographic analysis revealed that 19 samples were contaminated by aflatoxin zearalenone and/ or zearalenol.
