- Abstract
In this study, microbiological properties of chicken breast and thigh sold in Tokat were determined. For this purpose, 25 chicken breast and 25 chicken thigh samples obtained from butchers and markets were analyzed for total mesophilic aerobic bacteria, total psychrotrofic aerobic bacteria, yeasts-molds, total coliform, fecal coliform, Staphylococcus aureus, Bacillus cereus, and Clostridium perfringens. The presence of Escherichia coli, E. coli 0157:H7, Listeria monocytogenes and Salmonella spp. were also investigated in these samples. The counts for total mesophilic aerobic bacteria were 8.50x104-9.70x108 cfu/g and 2.70x105-4.84x108 cfu/g in the chicken breast and thigh samples, respectively; for total psychrotrofic aerobic bacteria 1.70x104-9.35x108 cfu/g and 1.74x105- 2.06x108 cfu/g; for yeasts and moulds 2.50x103-3.20x104 cfu/g and 2.50x103-1.35x105; for total coliform 4.30x101-2.30x106 cfu/g and 2.30x101-9.30x105 cfu/g; for fecal coliform 10.36x101-9.30x103 cfu/g and 2.30x101-2.30x104 cfu/g; for Staphylococcus aureus <102-3.52x105 cfu/g and <102-2.02x105 cfu/g; for Bacillus cereus 1.10x103-1.10x105 cfu/g and 2.20x103- 7.40x104 cfu/g, and for Clostridium perfringens 1.90x103-4.90x103 cfu/g and 2.00x103-5.70x104 cfu/g. Based on confirmation and identification tests, E. coli biotype 1 was found in 21 (84%), E. coli biotype 2 in 2 (8%), E. coli 0157:H7 in 6 (24%), Listeria monocytogenes in 3 (12%), and Salmonella spp. in 11 (44%) chicken breast samples. Of the 25 chicken thigh samples, 24 (96%) contained E. coli biotype 1,2 (8%) E. coli biotype 2, 6 (24%) E. coli 0157:H7, 4 (16%) Listeria monocytogenes and 13 (76%) Salmonella spp. In conclusion, chicken breast and thigh samples examined could threaten human health due to very high microbial counts and the presence of many food borne pathogens.
