Since the food safety and the foodborne diseases are becoming a main health concern in developing countries, the aim of this study is to determine, in accordance with the specific international standards, the compliance of the main frozen imported fish and fresh chilled fishes marketed and consumed in Northern Benin. From December 18 to March 5, 2019, the microbiological quality of the two main imported frozen fish (Scomber scombrus and Trachurus trachurus) and the two main freshwater fish locally produced (Clarias gariepinus and Oreochromis niloticus) and marketed in Benin were analysed in accordance with ISO standards specific to each germ counted as Colony-Forming Units (CFU). The Mesophilic aerobic flora and fecal coliforms loads in fresh chilled fishes (256,577 and 349.6 CFU, respectively) are significantly higher (p<0.05) than in the frozen fish (143,620 and 157.0 CFU, respectively) marketed in the northern Benin. T. trachurus seems more contaminated (p<0.01) by these germs than S. scombrus, and O. niloticus showed significantly higher loads (p<0.01) of these bacteria than the C. gariepinus. No salmonella colony was observed in all the samples, and in the fresh and frozen fish, Staphylococcus aureus (11.27 and  10.77 CFU, respectively) and Sulfite-Reducing Anaerobes (0.38 and  0.38 CFU, respectively) loads showed no significant differences (p>0,05) both between origin and between species. However,  the microbiological quality of all fish both imported frozen  fishes and fresh fishes analysed during this study have not comply with the requirements of the standard AFNOR (2000) specific to frozen fish and fresh chilled fish. They are so classified as “unsatisfactory hygienic” due to their very high fecal coliforms loads. It would therefore be interesting to raise awareness among stakeholders in the marketing system for fish products on good hygiene practices and the HACCP approach.

This study aimed to determine the effect of ovaprim hormone, aromatase inhibitor and pituitary on the quality of the catfish eggs (Clarias gariepinus). Experimental Design used was Completely Randomized Design (CRD) with four treatments, each with three replications. Treatment A: ovaprim; treatment B: Aromatase inhibitors, treatment C: hypophysis and treatment D: Control. The results showed that the difference in treatment gave highly significant effect on fertilization and hatching eggs but no significant effect on the survival rate of larvae. Aromatase inhibitor hormone was the best because it provided highly significant effect on fertilization (92.66%), hatchability of eggs (95%), and surviva rate (81.33%) of fish larvae.   Keywords : Clarias gariepinus.

Domiati cheese is the most popular brand of cheese ripened in brine in the Middle East in terms of consumed quantities. This study was performed to investigate the impact of the microbiological quality of the used raw materials, the applied traditional processing techniques and ripening period on the quality and safety of the produced cheese. Three hundred random composite samples were collected from three factories at Fayoum Governorate, Egypt. Collected samples represent twenty-five each of: raw milk, table salt, calf rennet, microbial rennet, water, environmental air, whey, fresh cheese, ripened cheese & swabs from: worker hands; cheese molds and utensils; tanks. All samples were examined microbiologically for Standard Plate Count (SPC), coliforms count, Staphylococcus aureus (S. aureus) count, total yeast & mould count, presence of E. coli, Salmonellae and Listeria monocytogenes (L. monocytogenes). The mean value of SPC, coliforms, S. aureus and total yeast & mould counts ranged from (79×102 CFU/m3 for air to 13×108 CFU/g for fresh cheese), (7×102 MPN/ cm2 for tank swabs to 80×106 MPN/ml for raw milk), (9×102 CFU/g for salt to 69×106 CFU/g for fresh cheese) and (2×102 CFU/cm2 for hand swabs to 60×104 CFU/g for fresh cheese), respectively. Whereas, E. coli, Salmonella and L. monocytogenes failed to be detected in all examined samples. There were significant differences in all determined microbiological parameters (p ≤0.05) between fresh and ripened cheese which may be attributed to different adverse conditions such as water activity, pH, salt content and temperature carried out to improve the quality of the product.
