is however presented for 2011 and onwards; the year when denmark started to susceptibility test all serotypes according to eu legislation. in danmap, s. typhimurium includes the monophasic variants with antigenic formulas s. 4, [5],12:i:- as recommended by the european food safety authority [efsa journal 2010. 8(10): 1826]. in the text, the term generic s . typhimurium refers to results on
isolates
of the non-monophasic variants only. in 2014 the panel for susceptibility testing was changed to follow the recommendations of efsa by excluding apramycin, ceftiofur, florfenicol, neomycin, streptomycin and spectino- mycin and including ceftazidime, meropenem and tigecycline instead. mic distributions for

? all serotypes in total, 803 samples from
pigs
caeca (
pigs
) and 15,905 pig carcass swabs (
pork
) yielded 217 salmonella
isolates
tested for antimicrobial resistance. as in the previous years, s. typhimurium (including the mono- phasic variants) and s. derby were the most common sero- types isolated from danish
pigs
and
pork
in 2015; representing 92% of all the
isolates
(figure 6.1). the majority of s. derby
isolates
from danish
pigs
and
pork
were fully sensitive to all antimicrobial agents tested in opposition to s. typhimurium, where only 15% of
isolates
exhibited full sensitivity. the serotype distribution has remained fairly constant in denmark in many years suggesting a stable endemic situation for sal- monella serotypes in the pig population with no rare outbreak antimicrobial agent
