Abstract
This study was carried out to investigate the microbial count of carcasses slaughtered inside and outside the abattoir and to investigate the effect of seasonal variation on different microbial categories, also to explore the effect of sampling sites on different microbial count. Our results indicated that aerobic Plate count of carcasses slaughtered inside and outside the abattoir from different sites were ranged from 5.803 ± 0.584 to 6.0343±0.0614/cm2, respectively.
The significant difference was found between winter and spring for abdomen and found in winter only between thigh samples. Significant difference between shoulder samples was also found in winter while no significant difference was found among all four seasons for neck. For enterobacteriaceae count, significant difference was found in shoulder region in winter season only. For mould and yeasts counts, there were no significant difference among all sites during all seasons. Our study revealed that microbial counts were within the recommended permissible limits. Under the non-satisfactory hygienic conditions followed in the Egyptian abattoirs no difference in the bacterial load was found between carcasses slaughtered in the municipal abattoirs and that of home killed animals. Hygienic standards should be strictly followed in Egypt.
