Abstract

ONE hundred random samples of cattle meat, liver, kidney and heart (25 of each) were collected from Shibin el kum abattoir, Menoufia, Egypt. All the collected samples were examined for demonstration of E. coli, Salmonellae and S. aureus.
The achieved result in this study indicated that incidence of E coli, salmonella and S. aureus were 36%, 28% & 56% for meat samples; 40%, 36% and 60% for heart samples; 52%, 44% and 72% for liver samples and 68%, 48% and 80% for kidney samples, respectively. Further, E. coli, Salmonellae and S. aureus were serologically identified.
The incidences of S. aureus enterotoxins in the examined samples of cattle were recorded. Enterotoxin A was detected in meat, liver and kidney samples and enterotoxin B from the kidney sample, enterotoxin D from the meat samples, A & C from heart and kidney and C & D from liver samples. Accurately, E coli strains were the resistant antibiotics against Erythromycin and Streptomycin. While, Salmonellae was resistant to Oxacillin and Streptomycin, however, S. aureus strains were resistant to Neomycine and Kanamycine.
