| A total of 40 Imported hen's eggs collected from Giza market were subjected to physi cal and mycological examinations. The defects met with in this investigation, included faulty shell (100%), aged egg (95%), cracked shell (7.5%) and leakered egg shell(5%), 38 samples showed a sided yolk where 2 only had a spready yolk. The mycological study revealed that, all the examined eggs were contaminated. Croup analysis of isolates showed that they belonged to 6 different species of molds: Peni cillium (65%), Asp < /strong>ergillus (37.5%), Mucor (10%), Cladosporium (7.5%), Paeoilomyces (7.5%) and Alternaria (2.5%). Identification of isolated Aspergillus spp. showed that, the A. flavus Link was the most prevalent constituting (17.5%) while A. nidulans (Eldam) wint, and A. clavatus Des. were the least (2.5%). A. amstelodami (angin) Thom and Church and A. fumigatus Fresenius lie in between with a frequency percentage of 7.5% and 5%, respectively. Penicilium verrucosum var.cyclopium (Westling) Samson,Stolk and Hadlok, P.chrysogenum Thom, P.candidus Link and P.frequentans Westling could be isolated from contaminated eggs with an incidence percentage of 35%, 20%, 7.5%, and 2.5% respectively. Hygienic significance of Isolates and the control measures for improring the.qqality of the product were discussed. | ||||
