Prévalence des Escherichia coli résistants aux céphalosporines de troisième génération ou aux carbapénèmes dans les viandes fraiches a la distribution en France

Abstract : In the framework of extended-spectrum cephalosporin- or carbapenem-resistant Escherichia coli (E. coli) surveillance in retail meat in France, no carbapenem-resistant isolates were detected from 1935 samples of broiler chickens, pork and beef between 2016 and 2019. The proportions of extended-spectrum β-lactamases- or cephalosporinase (ESBL/AmpC)-producing E. coli were low and stable in pork [0.3-1.2%] and beef [0.3-0.6%] from 2017 to 2019. However, 62% of poultry meat in 2016 was positive for ESBL/AmpC-producing E. coli, although this proportion dropped significantly to 26% in 2018 (Chi², p<0,05). Analysis of the genes involved in these resistance mechanisms, the characterization of their genetic support, and identification of the virulence genes associated with these strains can help define the proportion of human contamination by C3Gresistant E. coli originating in French retail meat
