Abstract
Contamination of meat at the retail level is very common. The presence of enteric pathogens on the meat surface will render the meat unsafe to the consumer as they are encountered in causing food poisoning and also they reflect the hygienic standard of the butchers’ shop. In recent study a total of 150 random samples of retailed sheep and goat meat, liver and kidney (25 samples of each) were collected from different butcher’s shops and abattoirs at El Gharbia Province. The collected samples were examined bacteriologically for detection of some enteric pathogens as E coli,Salmonella, Shigella spp., Yersinia spp., Vibrio spp. and Aeromonas hydrophiliaThe obtained results could be summarized in the following points:
1. Detection of enteric pathogens in the examined samplesof sheep:• E. coli was detected in sheep muscle, liver and kidneys on (13) 52 %, (10) 40% and (9) 36% of the examined samples, respectively.

On the basis of the previously mentioned results, enteric pathogens still constitutes common contaminants of meat and meat products and its presence in meat is very important due to its public health significance, good hygienic measures must be applied to obtain safe and wholesome meat.
