Abstract:
Background and Objective: Fungi and their spores are everywhere in the environments and most of them are mycotoxigenic. These micro-organisms can possibly contaminate the meat during processing chain such as slaughtering, feather plucking, evisceration and storage. Thus, this study was conducted to assess the effect of dietary garlic (Alliumsativum) supplementation on the meat quality of quail carcasses through evaluation of mycological contamination that of public health concern. Materials and Methods: A total of 101 day old Japanese quail chicks were divided into two groups (n = 50/group): Control group without garlic supplement and treated group with garlic supplement for 42 days. After slaughter, surface samples were collected from breast and thigh muscles of fresh and frozen quail carcasses. Results: The results showed that total mold and yeast counts in garlic supplemented group were lower in breast and thigh muscles than control group. Moreover, a lower incidence of molds and yeasts were detected in garlic supplemented group (either breast or thigh muscles) as compared to control group. In particular, the mold and yeast contamination was higher in fresh quail carcasses than frozen ones. The isolated mold species were Aspergillus spp. (37, 22) Mucor (19, 11), Penicillium spp. (45, 29), Fusarium spp. (10, 5), Rhizopus (1, 1), Alternaria (2, 0) and Absidia spp. (1, 0) from control and garlic supplemented groups, respectively. The isolated Aspergillus strains were A. flavus (17, 9), A. fumigatus (9, 6) and A. niger (11, 7) from control and garlic supplemented groups, respectively. Conclusion: This study confirmed the importance of garlic supplementation as antifungal agent in the quail diet for a clear and significant reduction of mold and yeast loads in quail carcasses.
