Thirty (30) samples were analyzed for anti-microbial resistance (AMR), total and fecal coliforms, Staphylococcus aureus, and Salmonella spp. using standardized methods during the period from March to September 2016. Antibiotic sensitivity was determined using the agar diffusion method. The total mesophilic aerobic flora ranged from 3.65,10⁵ to 3.68,10⁶ CFU/g. Total coliform ranged from less than 10 to 4.44,10³ CFU/g, while fecal coliform ranged from less than 10 to 3.91,10³ CFU/g. As for Staphylococcus aureus, the loads ranged from 1.20,10² CFU/g to 2.34,10³ CFU/g. No salmonella colonies were detected. Microbiological analyses showed that 36.70% of samples were unsatisfactory for TAMF bacteria, 46.70% were unsatisfactory for fecal coliforms, 76.70% were unsatisfactory for total coliforms, and 6.66% were unsatisfactory for Staphylococcus aureus. Research into antibiotic-resistant bacteria showed that all Pseudomonas aeruginosa were resistant to nalidixic acid, amoxicillin-clavulanic acid, ceftriaxone, and tetracycline, and 50% were resistant to trimethoprim-sulfamethoxazole. About Staphylococcus aureus, all isolated strains showed intermediate or absolute resistance to nalidixic acid, amoxicillin-clavulanic acid, ceftriaxone, and trimethoprim-sulfamethoxazole, while 75% were resistant to tetracycline. All strains of Escherichia coli and Enterobacter cloacae were resistant to amoxicillin-clavulanic acid, while 50% showed intermediate or absolute resistance to nalidixic acid and tetracycline. All strains of Enterobacter cloacae showed intermediate or absolute resistance to ceftriaxone. These results show that grills fish, Kanda, and fish rice are mostly contaminated and harbor antibiotic-resistant bacteria that can be transmitted to humans through food.]]> Abdoullahi Hissein Ousman, Bougma Sanogo, Ouédraogo Nicolas, Djimbo Adjam, Valery Mbaigolmem Beral, Tapsoba François, Savadogo Aly, Tidjani Abdelsalam 2026-01-19 Science and Education Publishing 2026-01-19 1 14 1 7 10.12691/ajidm-14-1-1
