Effect of the Presence of Antibiotic Residues on the Microbiological Quality and Antimicrobial Resistance in Fresh Goat Meat.

A total of 11 fresh goat legs were collected at the retail level. Mesophiles, spp., , , , spp., and counts were determined. Nine samples were free of antibiotic residues, while in the other two samples the presence of sulfadiazine and doxycycline was detected. The antimicrobial resistance of , , spp., and isolates was also evaluated. was found in two samples. Methicillin-resistant was detected in one sample. isolated from one sample containing doxycycline residues showed resistance to mupirocin. Moreover, multi-resistant and were found. Most of the isolated were multi-resistant. Neither extended-spectrum β-lactamase -producing nor vancomycin-resistant enterococci were detected in any sample. The presence of doxycycline or sulfadiazine could affect the goat meat microbiota since less microbial diversity was found in these samples compared to those free of antibiotics. The presence of antibiotic residues could increase the antimicrobial resistance of in fresh goat meat. The presence of multidrug-resistant bacteria in goat meat could be considered a potential threat and should be monitored. Special measures should be taken at the farm level and during slaughter to reduce antimicrobial resistance.
