Abstract

This study was conducted to record the potential risk of some pathogens in table eggs in Beni-Suef city, Egypt. A total of 100 table eggs samples (Farm and Baladi eggs) were randomly collected from poultry farms, markets, supermarkets and groceries in Beni-Suef city, 50 farm eggs samples (each of 3 eggs) and 50 baladi eggs samples (each of 5 eggs) were examined for the presence of coliforms, E.coli, Salmonella, coagulase positive Staphylococcus aureus and Staphylococcal enterotoxins. Isolates were identified by biochemical, serological and molecular (PCR) methods. The obtained results in the present study revealed that (22%) of the examined samples were contaminated with Coliforms. The other identified genera were Citrobacter freundii, Citrobacter diversus, Edwardsiella tarda, Enterobacter spp., Morgonella morganii, Klebsiella oxytoca, Providencea spp., Serratia fonticola and Yersinia intermedia. E.coli (atypical type) was detected in a percentage of 27.27%. True  fecal E. coli and Salmonella spp.  failed to be detected in any of the whole examined 100 eggs samples. Additionally,  Staphylococcus spp. was detected with incidence rate of (13%), out of  them, 8 (61.5%)  isolates were accounted for coagulase positive Staphylococcus aureus. Enterotoxin profiling revealed that two classical enterotoxin genes (SEA and SED) were detected either singly or in combination. The potential health hazards and the suggested control measures of the isolated strains had been discussed.
