Antimicrobial resistance is a daunting public health threat impacting both human and animal health and it is a cause for concern wherever antimicrobial agents are in use. The usage of antimicrobial drugs in food producing animals could results in significant food safety issue - antimicrobial resistance among zoonotic bacteria in these animals. Resistance monitoring program still does not exist in Serbia, so we made a pilot program to screen the situation in our abattoirs. We found similar situation like the one in EU. The resistance to one or more antimicrobial drugs was found in 40.00% and 75.32% Campylobacter spp. strains isolated from poultry and pig carcasses, respectively. Fluoroquinolones are antimicrobial drugs which, beside beta-lactams, are most often used in poultry breeding. Fluoroquinolones are also very important for treatment of some human diseases. We examined relationship between presence of fluoroquinolone resistant C. jejuni in poultry carcasses and fluoroquinolone treatment of poultry. Treatment with one of this antimicrobials - enrofloxacine selects resistant strains in chickens carcasses, C. jejuni strains resistant to enrofloxacine were isolated from all livers (100%) and 70% carcasses. The resistant bacteria may then be transmitted to humans through food supply and increase the risk of treatment failures. Resistant zoonotic pathogens in food have to be controlled through a complete, continuous farm-to-fork system.
