Screening of antibiotics residues in beef consumed in Ouagadougou, Burkina Faso

Abstract

The anarchic use of antibiotics for therapeutic purposes or as a growth factor in Burkina Faso’s breeding is the origin of their residues present in consumed meat. These antibiotics residues have health, technological and microbiological consequences. The objective of this first study is to highlight the antibiotic residues in meat consumed in Ouagadougou, Burkina Faso. A survey was carried out to make an inventory of antibiotics used for animal treatment intended for production and the consequences of such use. Thus, a total of 100 samples of bovine kidney were deducted from the refrigerating slaughter house of Ouagadougou aseptically to test the presence of drug residues with the Premi®Test kit and the microbiological method with Geobacillus stearothermophilus var. calidolactis ATCC 10149. According to this analysis, 31% of the kidney samples contained aminoglycosides, quinolones, macrolides and beta-lactam, sulfonamides and/or tetracyclines causing the zones of inhibition 3 to 15 mm. This reflects the anarchic use of antibiotics in Burkina Faso cattle breeding. Measures must be taken to ensure consumer safety and reduce the impact of these antimicrobials on selection of resistant pathogenic bacteria strains. Key
