*Only serotypes with ≥40 isolates are included. 
†Only subsets of selected serovar are routinely tested for susceptibility to antimicrobial agents.
‡Indicates serotypes with >30 samples from Danish produced meat and >30 samples from imported meat, which were statistically tested. 
§Indicates clinical significance.
