Prevalence and Antibiogram Assessment of Staphylococcus aureus in Chicken Carcass Rinse Water at Artisanal Slaughterhouses in Abidjan District, Côte d’Ivoire

Aims: The aim of the current study was to determine the antibiotic resistance profile of Staphylococcus aureus strains isolated from rinse water of chicken carcass in artisanal slaughterhouses in Abidjan.

Place and Duration of Study: Chicken’s rinse water samples were collected between January and March 2020 in three areas of Abidjan district.

Methodology: A total of 75 rinse water samples were collected from three markets of Abidjan district. Enumeration and isolation of S. aureus were carried out on Baird Parker agar supplemented with egg yolk tellurite emulsion followed by morphological and biochemical identification. Antibiotics resistance profiles were performed by using disks diffusion methods.

Results: Out of 75 samples, 21 (28%) were contaminated with S. aureus. Among the isolates, 21 (one by positive sample) were tested for antimicrobial resistance against 14 most commonly used antibiotics. All strains were resistant to two antibiotics (minocyclin and fusidic acid). However, some drugs such as gentamiycin, norfloxacin, and Tigecyclin showed great activity on tested isolates.

Conclusion: Results of this study suggest that rinse water could consist of a major critical point of chicken carcass contamination by S. aureus with high drugs resistance capacity. Therefore periodic control is need to good hygiene practice and improving the poultry meat sanitary quality produce from these slaughterhouses.
