Between June and September 2023, a total of 80 meat samples from pork and chicken meatwere collected from 16 retail markets in La Plata, Argentina. Eighty-four highest priority criticallyimportant antimicrobial-resistant Escherichia coli and two Salmonella spp. were isolated. Resistance to ciprofloxacin and cefotaxime was observed in 65 and 49 E. coli isolates, respectively. Seventy-fiveE. coli isolates were multidrug resistant. Fourteen E. coli isolates from chicken meat showed resistance to three of the HPCIA. Resistance to third-generation cephalosporin was associated with blaCTX-M. It is 15 times more likely to find HPCIA-resistant E. coli in chicken meat than in pork.
