Abstract

The presence of antibiotic residue in chicken and animal meats is a serious threat to human health due to its harmful effects. This study aimed at identifying the antibiotic resistance patterns of the isolates as well as antibiotic residues in chicken, cattle, buffalo and goat meats in different southern districts of Bangladesh. A total of 205 meat samples, including 70 chicken meat, 60 cattle meat, 50 buffalo meat and 25 goat meat were aseptically collected and analysed for the detection of antibiotic residues by thin layer chromatography and the isolates obtained from these samples were subjected to antibiogram study against 16 commonly used antibiotics. The isolates found in this study were Staphylococcus spp., Streptococcus spp., Escherichia coli, and Salmonella spp. and their prevalence were 37.5% (77/205), 22.1% (48/205), 29.7% (61/205), 8.7% (19/205), respectively. The isolates showed different degrees of sensitivity to the antibiotics used in the study. The most resistant phenotype was against cefradine, amoxicillin, penicillin, oxytetracycline, erythromycin, and enrofloxacin. 18.5% (38/205) meat samples were found to be positive for antibiotic residues and the highest prevalence was observed in chicken meat compared to other meat types. Overall, the findings of the study suggest that it is important to take controlling measures for the emergence of antibiotic resistance and also for ensuring healthy meats for human consumption.

Highlights

In veterinary medicine antibiotics are commonly used, foods derived from animals may contain antibiotic residues, which can adversely affect the human health (Chanda et al, 2014)
Each sample was divided into two aliquots, one aliquot was shipped to the laboratory of the Department of Microbiology and Public Health, Patuakhali Science and Technology University for isolation and characterization of isolates and another aliquot was shipped to the laboratory of the Department of Microbiology and Veterinary Public Health, Chittagong Veterinary and Animal Sciences University, Chittagong for antibiotic residue detection by thin layer chromatography (TLC)
The antibiogram study revealed that the isolated Staphylococcus spp. were highly resistant to cefradine followed by amoxicillin, penicillin, chloramphenicol, erythromycin

Summary

Introduction

In veterinary medicine antibiotics are commonly used, foods derived from animals may contain antibiotic residues, which can adversely affect the human health (Chanda et al, 2014). Administration of antibiotics to farm animals may impose certain hazards to human and animal health, including increased resistance of bacteria to antibiotics as well as allergic reaction (Walton 1988; Mathew et al, 2001). Worldwide farmers use antibiotics for therapeutic and prophylactic purposes, and as growth promoter (Jinap et al, 2010; Wadoum et al, 2016). Antibiotics belonging to tetracycline, aminoglycoside, sulphonamide and potentiated sulphonamide, macrolide and lincosamide groups are commonly used as growth promoter at sub-therapeutic doses in poultry
