We described and characterized Shiga-toxin-producing Escherichia coli (STEC) strains with high levels of resistance to azithromycin isolated in France, between 2004 and 2020. Nine of 1715 (0.52%) STEC strains were resistant to azithromycin, with an increase since 2017. One isolate carried a plasmid-borne mef(C)-mph(G) genes association, described here for the first time in E. coli. Azithromycin resistance, although rare, needs consideration as this treatment may be useful in case of STEC infection.
