characterised a collection of 300
isolates (including human, food, animal and environmental isolates)
from 42 countries in 5 continents. The authors reported
clonal complexes CC9 and CC121 as frequent clones in many
countries, especially CC9, which ranked the 4th most common
clone in all world regions (third in Europe) behind CC1, CC2 and
CC3. Our results demonstrate than ST9 and ST121 are clones that
are highly adapted to the meat-processing environment that can
contaminate the final meat product. Such adapted strains have
been reported by other authors
