Microbiological Analysis of Dried Goose Carcasses

“…Coliform bacteria were counted at the average number of log 10 2.67 CFU g -1 in 58% of the goose wing samples. Other investigators (47) counted coliform bacteria in the range numbers of log 10 3.49 to 5.42 CFU g -1 which are higher than the result found in this study. Enterococci were detected in all goose wing samples at the average number of log 10 4.34 CFU g -1 , while clostridia were isolated from 42% of the wing samples at the average number of log 10 0.69 CFU g -1 .…”

“…Clostridia was detected in only one of the goose thigh samples at the average number of log 10 0.11 CFU g -1 , whereas other researchers (38,46) found clostridia at higher numbers of 2.2x10 2 and log 10 1.00 CFU g -1 respectively in the chicken thigh samples. No coagulase positive stahylococci were detected in the goose thigh samples, same as Ucar et al (13) who could not isolate any staphyloccus in the goose thigh samples, while other authors (44,45,47) isolated staphylococcus at the numbers of 3.6x10 2 CFU g -1 , log 10 2.47 to 3.48 CFU g -1 and 6.2x10 2 CFU g -1 in the chicken thigh samples, respectively. Yeasts were detected in 100% of thigh samples at the average number of log 10 5.19 CFU g -1 , whereas moulds were isolated only from 25% of the goose thigh samples at the average number of log 10 0.82 CFU g -1 .…”

“…However, it is reported that there is no isolate of staphylococci in goose wing samples (13). In other studies (45,47) Staphylococcus aureus were found at the max. number of 3.48 CFU g -1 and 8.8x10 2 CFU g -1 respectively, which is quite higher than the number of staphylococci in our study.…”

“…Wing samples: In the twelve goose wing samples, aerobic mesophilic bacteria were enumerated at the average number of log 10 6.85 CFU g -1 . It was reported (13) a lower number of log 10 3.82 CFU g -1 aerobic mesophilic bacteria in their goose samples, while some researchers (45,47,50), isolated aerobic mesophilic bacteria at the numbers of 6.41 CFU g -1 , log 10 5.56 to 7.28 and 1.3x10 8 CFU g -1 in the chicken samples, respectively. These results are lower than our result in this study.…”

“…Enterobacteriaceae were isolated in 100% of thigh samples at the average number of log 10 5.29 CFU g -1 , while coliforms were detected in 75% of the thigh samples at the average number of log 10 3.09 CFU g -1 . Likewise, Astorga et al (47) reported the numbers of log 10 3.49 to 5.42 CFU g -1 coliform bacteria in their chicken thigh samples, whereas Kundakci et al (46) counted the numbers of 3.7x10 3 CFU g -1 coliforms in the chicken thighs. The number of coliforms in the goose thigh samples showed similarity with these results, but higher numbers of coliforms in the chicken thighs have also been reported at the average numbers of 4.1x10 3 and 1.9x10 4 CFU g -1 in two studies (38,49).…”
