All Salmonella isolates tested were susceptible to meropenem. N: number of isolates tested; % Res: percentage of microbiologically resistant isolates.
a
A number of colistin‐resistant isolates are undergoing testing for the presence of the mcr‐1 gene. The reported occurrence of colistin resistance does not equate to the occurrence of mcr‐1. ECOFF applied 2 mg/L.
b
ECOFF applied 1 mg/L.
