study on the fungal contamination and prevalence of Aflatoxins and some antibiotic residues in table eggs

ABSTRACT

A total of fifty random table egg samples were collected from EL-Beida city markets and subjected to mycological examination as well as the detection of residues of aflatoxin and inhibitory substances. The mean total mould and yeast counts of optically clean egg shell and soiled egg shell were 2.7 X 10[4] +/- 2.2 X 10[4] and 3.7 X 10[5] +/- 3.2 X 10[5], respectively. The mean mould and yeast count in egg content were 6.6 X 10[3] +/- 3.1 X 10[3] and 2.5 X 10[4] +/- 1.1 X 10[4], respectively. Aflatoxin residues were detected only in 7 samples and the mean aflatoxin content residues was 0.542 +/- 0.226 ppb. Residues of inhibitory substance were detected in 4% of the examined egg samples
