Abstract from a total of 100 random samples of chicken meat “50 of both types rural and industrial poultry meat” were collected from different private poultry shops, supermarkets and retailing shops in Alexandria province, where these samples were subjected to microbiological examination for counting of total (mesophilic bacterial count, total enterobacteriaceae count and total mould and yeast counts) and isolation and identification of (Salmonella, E.coli and Staphylococcus aureus). The obtained results revealed the following: Total mesophilic bacterial count: All examined samples of both rural and industrial meat contaminated with mesophilic bacterial count. In rural poultry meat ranged from 1.3 x104 to 8.3 x105, with a mean value 1.7x105± 3.1x104 cfu/g, but in industrial poultry meat ranged from 9.0x103 to 6.3x105, with a mean value 1.19 x105± 2.3x104, respectively. Total enterobacteriaceae count: Incidence of enterobacteriaceae was 100 % in all examined poultry meat, total Enterobacteriaceae count in the examined samples of rural poultry meat were ranged from 3.1 x104 to 1.15 x105,with a mean value of 6.4x104± 2.9x103 cfu/g and industrial type from 6.4x104 to 5.8x105,with a mean value of 2.34 x105± 3.0x104 cfu/g, respectively. Total moulds and yeasts counts: The total yeast and mould count in the examined samples of rural poultry meat were ranged from 3.8 x104 to 7.1 x105,with a mean value of 2.6x105± 2.2x104 cfu/g and industrial type from 1.9x104 to 3.4x105,with a mean value of 1.9 x105± 1.18x104 cfu/g, respectively. Isolation and identification of Salmonellae: The obtained results indicated that Salmonellae were isolated from both rural and industrial poultry meat samples with an incidence of 18 % and 12 %, respectively. Isolation and identification of Escherichia coli: The obtained results indicated that E.coli organisms were isolated from both rural and industrial poultry meat samples with an incidence of 58 % and 36 %, respectively. Isolation and identification of Staphylococcus aureus: Incidence of +ve Coagulase positive Staphylococcus aureus is 62 % and 32 % from both rural and industrial poultry meat samples. The significance of isolated enteropathogens and their possible sources of contamination as well as some recommendation to avoid their presence in poultry meat either from rural and industrial poultry were discussed. |
