Abstract
The research aimed to evaluate the thighs meat of the imported frozen chicken (chemical, specific and microbial) in Diwaniya city .The results of chemical analysis showed that Brazilian thighs meat for Sadia mark has recorded the highest percentage of Dry matter and Carbohydrates were 31.640% and 0.780% respectively, while American Tyson mark recorded the highest percentage of Ash and Fat were 0.975% and 10.390% respectively, and the highest percentage Moisture and Protein were for Brazilian mark of the Alkafil attain to 68.443% and 19.647%, also the specific estimates which included pH, total volatile nitrogen and the peroxide value were done and the highest rate in Sadia mark were 5.900 and 9.533mg/100g and 5.133 respectively, and the microbiological test pointed to the level of the microbial contamination through the content of total aerobic bacteria count where the results showed that the American meat recorded most contamination 12.6×104CFU/gm,while the coli form bacteria was more contamination for Alkafil meat which was 9.6×10³ CFU /gm.The results appeared that the highest rate of proteolytic bacteria and psychrophilic bacteria were for the thighs meat of Sadia mark were 10.46×104 CFU/gm and 10.6×105 CFU /gm respectively, and Alkafil mark was recorded the highest rate for fungi 57×10² CFU/gm, whereas concerned with pathological bacteria, Alsadia meat recorded the highest percentage of Salmonella and Listeria were 95% and 88% respectively, while appeared American Tyson mark the highest percentage of Brucellosis was 22%.
