“…Antimicrobial resistance is frequently detected in bacteria that are isolated from food producing animals because of their extensive and inappropriate use of antibiotics as growth promoters or as preventive treatments [ 27 ], thus resulting in the emergence of antimicrobial resistance in foodborne pathogens and commensal bacteria in the food of animal origin [ 28 ]. Pig production is an intensive industry for which the use of antibiotics for treatment of various diseases is widely diffused [ 27 ]. In addition, the current scenario of the anthropogenic transformation of the landscape involves forcing wildlife into greater contact with humans and their livestock, thereby increasing the risk of antimicrobial resistance transmission through different populations [ 29 ].…”

Antimicrobial-resistant foodborne microorganisms may be transmitted from food producing animals to humans through the consumption of meat products. In this study, meat that was derived from farmed pigs and wild boars was analyzed and compared. Escherichia coli (E. coli) were isolated and tested phenotypically and genotypically for their resistance to quinolones, aminoglycosides and carbapenems. The co-presence of AMR-associated plasmid genes was also evaluated. A quinolone AMR phenotypic analysis showed 41.9% and 36.1% of resistant E. coli derived from pork and wild boars meat, respectively. A resistance to aminoglycosides was detected in the 6.6% of E. coli that was isolated from pork and in 1.8% of the wild boar meat isolates. No resistant profiles were detected for the carbapenems. The quinolone resistance genes were found in 58.3% of the phenotypically resistant pork E. coli and in 17.5% of the wild boar, thus showing low genotypic confirmation rates. The co-presence of the plasmid-related genes was observed only for the quinolones and aminoglycosides, but not for the carbapenems. Wild boar E. coli were the most capable to perform biofilm production when they were compared to pork E. coli. In conclusion, the contamination of pork and wild boar meat by AMR microorganisms could be a threat for consumers, especially if biofilm-producing strains colonize the surfaces and equipment that are used in the food industry.

“…The major health issue related to AMR is linked to the acquisition of resistance genes by bacteria capable of zoonosis. Some pathogenic bacteria such as S. aureus and Escherichia coli can become resistant to a very large spectrum of antibiotics [ 38 , 39 ].…”
