Abstract

A total of 120 random samples of cattle shoulder meat, liver, kidneys and lungs (30 of each) were collected from two traditional abattoirs of Elbehira province. All collected samples were subjected to organoleptic, chemical and microbiological examinations to determine their quality. The results showed that the sensory characters (color, odor and consistency) and chemical parameters (pH with the mean of 5.70 ± 0.04, 6.45 ± 0.02, 6.49 ± 0.01, 6.48 ± 0.02, TVN with the mean of 12.68± 0.02, 13.06 ± 0.04, 12.76 ± 0.03, 12.98 ± 0.04 and TBA with the mean of 0.24 ± 0.01, 0.16 ± 0.01, 0.25 ± 0.01, 0.24 ± 0.01) for shoulder meat, liver, kidneys and lungs respectively were normal and accepted. On the other hand the results of microbiological examination in examined samples of shoulder meat, liver, kidneys and lungs revealed that the mean of total APC were 2.36×105 ± 48×103 , 20.1×104 ± 37×103,3.43×105 ±1.97×105 ,18.9×104 ±3.8×104, respectively. While the mean of Enterobacteriaceae count were 10.8×104 ± 2.6×104 , 84×103 ± 18×103 , 69×103 ± 17×103 , 84×103 ± 21×103, respectively, coliform count with the mean of 44×103±12×103, 34×103±7×103, 22×103±5×103, 32×103±8×103 respectively, total Staphylococci count with the mean of 28×103±5×103, 23×103±4×103, 23×103±5×103, 20×103±4×103 respectively, total mould with the mean of 1.24×102±0.64×102, 0.46×102±0.9×102, 0.49×102±0.1×102, 0.87×102±0.22 ×102, respectively and total yeast count with the mean of 2.59×102±1.41×102, 0.85×102±0.36×102, 0.23×102±0.07×102, 1.62×102 ± 0.8×102, respectively, were higher than the permissible limits and the examined samples failed to be accepted.
