Abstract
One hundred samples of ready to eat meat (25 each of fresh meat,
beef burger, luncheon and pasterma) collected from butchers’ shops and
markets located in Damanhour town and were subjected for bacteriological
examination.
The results obtained from bacteriological examination can be summarized
as follows:
- Total aerobic bacterial count. The count was ranged from 5.5 x 106 to
1.7 x io with a mean value of and 5.4 x 107 ± 8.9 x 106 CFU/g of
examined samples of meat. In beef burger, the count was 1 x io to
2.4 x 1O with an average value of 4.1 x 106 ± 1.4 x 106 CFU/g. For
luncheon samples, the range was 1 x 105 to 3.6 x 107 with a mean
count of 6.9 x 106 ± 1.7 x 106 CFU/g. While, in pasterma the total
aerobic count ranged between 2.9 xiO3 and 1.7 x 105 with a mean
value of 6.0 x io ± 1.0 x i0 CFU).g.
- Total psychrotrophic bacterial count. The average in examined meat,
beef burger, luncheon and pasterma was 7.0 x iO ± 1.4 x i07 2.4
x 106 ± 4.4 x 105; 6.9 x 106 ± 1.6 x 106 and 5.2 x 104 ± 1.2 x
CFU/g, respectively.
- Incidence of Pseudomonas species. The incidence of Pseudomonas
species in examined meat was found to be 8, 72 and 8% for
Pseudomonas a/cal/genes, Ps. fluorescens and Ps. frugi, respectively. While the incidence in beef burger was 8, 12, 60, 16 and 4%, respectively for Ps alcaligenes, Ps th,vnuta, Ps fluorescens, Ps frugi and Ps. pseudoa/caligenes, respectively. In luncheon, it was 12,4,48, 8 and 8% for Ps. a/cal/genes, Ps. diminuta, Ps. fluorescens, Ps. frugi and Ps putrefaciens, respectively In examined samples of pasterma, the incidence was 16, 52, 12, 4, and 4% for Ps. a/ca//genes, Ps. diminuta, Ps. fluorescens, Ps. pseudoalcaligenes, Ps. putrefaciens and Ps. vesicularis, respectively.
Incidence of Aeromonas species. The incidence of Aeromonas hydrophila and Aeromonas punctata was 72 and 16% in examined meat samples, 24 and 12% in beef burger, 44 and 24% in luncheon and 88 and 4% in samples of pasterma, respectively.
Incidence of Proteus species: The incidence of Proteus mirabills, P. morgan/i, P. rettgeri and P. vu/garis was 12,48, 8 and 4% in examined samples of meat, 16, 56, 8 and 8% in beef burger samples, 4, 4, 0 and 0% in examined samples of luncheon, and 36, 2, 12 and 0% in examined samples of pasterma, respectively.
The public health importance of isolated potential bacteria as well as suggested measures for protection of the consumer and improving the quality of meat and rheat products were discussed.
