Abstract EN

The study aimed to evaluate the bacterial quality of marketed poultry meat in five areas in Benghazi during the summer season by estimating the number of some evidence of contamina- tion, including the total number of bacteria, coliform bacteria, Staphylococcus aureus and identifi- cation of Salmonella.

The results showed that the total number of bacteria in all the studied areas on domestic chicken meat was between 3.84 and 7.22, with an average of 6.02 logioCFU/g, and in im- ported poultry between 4.49 and 6.73 and an average of 5.94 logioCFU/g.

Coliform bacteria was in local chicken meat between 3.5 and 6.80 averaged 5.53 logioCFU/g, and in imported poultry be- tween 3.0 and 6.80 and averaged 5.5 logioCFU/g.

Staphylococcus aureus in the five sectors be- tween 4.5 and 7.3 in domestic poultry meat, and in imported poultry meat was between 6.03 and 6.50.

Biochemical tests for 22 bacterial isolates found E.

coli 40.9%, Citrobacter spp.

18.2%, Klebsiella spp.

13.6%, Salmonella spp 9.1% and Pseudomonas spp 18.2%.

The results of this study indicate that there was a high percentage of contamination in chicken carcasses, especially local chicken carcasses, with pathogenic bacteria which reflect the low health quality of this meat due to the lack of good sanitary procedures during the preparation of chicken carcasses, storage, and dis- play of carcasses when selling.
