ABSTRACT

A total of 135 egg samples were collected from Kafr El-Sheikh and El-Gharbia Governorates markets [80 and 55 samples, respectively] for determination of their quality. The obtained results showed higher mean T.C.C. and yeast count values in egg shell samples collected from Kafr El- Sheikh Governorate than those in EL-Gharbia Governorate, while, the mean mould count values were higher in EL-Gharbia Governorate. Moreover, the egg content samples collected from Kafr El-Sheikh Governorate showed lower mean T.C.C. and mould count values and higher mean yeast count values than those in EL-Gharbia Governorate. Serological typing of the 8 salmonella isolates, 4 from each Governorate, revealed the presence of two serotypes; with an incidence percentage ranging from 25% to 75%. Residues of inhibitory substance were detected in 5% and 9.1% of the examined egg samples collected from Kafr EL-Sheikh and EL-Gharbia Governorates, respectively.
