AB For the first time, this study evaluates consumer exposure via poultry meat to Enterobacteriaceae with capacity to develop severe extraintestinal infections by either bacterial virulence and/or antibiotic resistance traits. The characterization of 256 isolates and the assessment of five parameters, showed that 96 of 100 poultry meat samples from supermarkets of northwest Spain posed ≥ one potential risk: i) 96% carried Enterobacteriaceae resistant to antimicrobials of categories A (64% to monobactams) or B (95% to cephalosporins 3rd and 4rd- generation, quinolones and/or polymixins) of the new categorization of EMA. ii) More than one extended-spectrum-β-lactamase (ESBL)-producing Enterobacteriaceae species were recovered from 28% of poultry meat. iii) High-risk lineages of E. coli, including multidrug-resistant ST131-H22, were present in 62% of samples. iv) E. coli recovered from 25% of samples conformed the ExPEC status. v) E. coli from 17% of samples satisfied the UPEC status. Of note, the recovery from different samples of two E. coli CC10-A (CH11-54) carrying mcr-1.1-bearing IncX4 plasmids, and four E. coli CC10-A (eae-beta1) of the hybrid pathotype aEPEC/ExPEC. (ESBL)-producing K. pneumoniae were isolated from 27% of samples. In summary, poultry meat microbiota is a source of genetically diverse Enterobacteriaceae, resistant to relevant antimicrobials and potentially pathogenic for consumers.
