Abstract

E. coli O26:H11 strains could outgrow O157:H7 companion strains in planktonic and biofilm phases, and also effectively compete with pre-colonized O157:H7 cells to establish themselves in mixed biofilms. E. coli O157:H7 strains were unable to displace preformed O26:H11 biofilms. Therefore, E. coli O26:H11 remains a potential risk in food safety.
