Screening of Veterinary Growth-Promoting Agent and Antibacterial Residues in Beef Cattle and Broiler Meats Consumed in Bursa, Turkey

Abstract

This study was aimed to determine residues of growth-promoting agents and some antibacterials in beef cattle and broiler meats consumedin Bursa, as well as to evaluate their hazards on public health. A total of 45 meat samples consisting of 36 beef cattle meat and 9 broiler meatsamples were collected from supermarkets and butchers between November and December in 2016. The analysis was carried out by biochiparray-based immunoassay technique. This system is also currently used for simultaneous detection and quantitation of different anabolicsconsisting of β-agonists, boldenone, corticosteroids, nandrolone, ractopamine, stanozolol, stilbenes, trenbolone and zeranol, and six groupof antimicrobials consisting of quinolones, cephalosporins, amphenicols, aminoglycosides, macrolides and tetracyclines. Although residuesof growth-promoting agents could not be detected in any of the samples, antimicrobial residues from all groups were detected in 10 beefcattle meat samples and tetracycline residues were detected in two broiler meat samples at various levels. In conclusion, there is no risk toconsumers for growth-promoter residues according to the results. The detected antibacterial levels were generally lower than hazardous concentrations of residue. However, some detected levels for quinolone, amphenicol, macrolide and tetracycline groups in beef meat samples,and detected concentrations for tetracycline group in two broiler meat samples exceeded the maximum residue limits, and could pose a riskfor public health.
