A wide distribution of some STs, mainly ST9 and ST121, was
observed. Both ST9 and ST121 included isolates from several
different plants that are geographically dispersed throughout
Spain. Moreover, these STs have also been recovered in RTE meat
products from 1994 to 2011, demonstrating its persistence through
the years. ST9 and ST121 strains have also been reported in several
European countries from different environmental, clinical and food
sources (Holch et al., 2013; Parisi et al., 2010; Ragon et al., 2008).
