Abstract
Chicken meat is highly preferred protein food worldwide. To meet the demand, huge poultry farms are established and using antibiotics as prophylaxis and treatment against the bacterial diseases. Uncontrolled usage of antibiotics has led to development of antibiotic resistance in poultry and antibiotic residues in poultry chicken. Fifty one chicken meat samples were collected from various retail outlets. Antibiotic residues were quantified by HPLC, total microbial load was measured by growth of bacteria on growth medium and antibiotic resistant profile of Escherichia coli, Salmonella spp, Staphylococcus aureus and Campylobacter spp was determined by well diffusion method. Except neomycin, all tested antibiotics were present in the range of 10-978 ppm, the average microbial load was in the range log 10 of 7.32 per gram of chicken sample, E. coli, Salmonella spp, Staphylococcus aureus and Campylobacter spp were resistant to several antibiotics studied. Hence there is a need of appropriate usage of antibiotics in poultry and proper handling of chicken during farming and slaughtering.
