Abstract

A total of 100 swabs, 50 swabs were taken from non closed esophageal and anal opening cattle carcasses and other 50 swabs taken from closed sophagus and anal opening cattle carcasses, were collected randomly from different places of cattle carcasses (neck, chest, abdomen and pelvic regions) in an moderate abattoir at Elbehaira governorate (abohomos abattoir) were they examined bacteriologically for total aerobic bacterial, psychrophilic bacterial, Enterobacteriaceae, Enterococcal, Staphylococcal and Mould and Yeast. Microbiological investigations of non closed esophageal and anal opening cattle carcasses revealed that the mean value of total aerobic bacterial count, psychrophilic bacterial count, nterobacteriaceae count, Enterococcal count, Staphylococcal count, Mould and Yeast count were 63.06×105 ± 2.23 ×105, 60.04 ×103±1.57×103, 65.64×104±1.72×104, 58.59×103±1.92×103, 12.32×103±0.50×103 and 7.69×104±0.67×104 cfc/g; respectively. While Microbiological investigations of closed esophageal and anal opening of cattle carcasses was 28.30×104±0.63× 104, 28.78 ×102±0.70×102, 28.75×103±0.81×103, 33.25 ×102± 0.66×102, 7.58 ×102 ±0.43×102 and 3.23×103±0.26×103 cfc/g; respectively. The present study indicated significance reduction in all microbiological counts on closed esophageal and anal opening cattle carcasses samples than on non-closed esophageal and anal opening cattle carcasses samples.
