Farm-level and pig-level <jats:italic>Salmonella<\/jats:italic> prevalences were 35\u00b75% and 2\u00b72% in 1998\u20131999, and 35\u00b77% and 3\u00b73% in 2004\u20132005. Prevalence by growth stage was 2\u00b74% for sows, 3\u00b73% for weaned pigs, 2\u00b77% for fattening pigs and 3\u00b78% for finishing pigs. The predominant serotypes identified were Agona (28\u00b74%), Typhimurium (17\u00b79%) and Infantis (16\u00b74%) in 1998\u20131999, and Typhimurium (32\u00b75%), Anatum (24\u00b76%) and Infantis (13\u00b75%) in 2004\u20132005. Compared with the 1998\u20131999 isolates, the 2004\u20132005 isolates showed significantly higher rates of resistance to all the antimicrobials except tetracyclines (<jats:italic>P<\/jats:italic>&lt;0\u00b701 to <jats:italic>P<\/jats:italic>&lt;0\u00b705) and resistance to \u2a7e2 antimicrobials [19\u00b74% (13\/67) <jats:italic>vs<\/jats:italic>. 39\u00b77% (50\/126), <jats:italic>P<\/jats:italic>&lt;0\u00b701].
