Abstract: The seroprevalence of Salmonella spp., pathogenic Yersinia spp., Toxoplasma gondii and Trichinella spp. was studied in 1353 finishing pigs from 259 farms that were allocated according to farm types: large fattening farms (1000 pig places), small fattening farms (<1000 pig places) and farrow-to-finish farms. The antibodies were analysed with commercial ELISA kits in meat juice samples that were collected at Finnish slaughterhouses. Salmonella antibodies were rare (3% of pigs, 14% of farms) when the cut-off optical density (OD) value 0.2 was used. Antibodies to pathogenic Yersinia spp. and T.gondii were detected in 57% of pigs and 85% of farms (OD 0.3) and in 3% of pigs and 9% of farms (OD 0.15), respectively. No antibodies to Trichinella spp. were detected (OD 0.3). The European Food Safety Authority (EFSA) considers Salmonella spp., Yersinia enterocolitica, T.gondii and Trichinella spp. as the most relevant biological hazards in the context of meat inspection of pigs. The seroprevalence of these important zoonotic pathogens was low in Finland, except that of Yersinia. The seroprevalence of Toxoplasma was significantly higher in pigs originating from small-scale fattening farms (P<0.05). Strong positive correlation was observed at the animal level between Salmonella and Yersinia seropositivity and between Salmonella and Toxoplasma seropositivity (P<0.05). We suggest that these results reflect the level and importance of biosecurity measures applied on the farms. Meat juice serology at slaughter is a useful tool for targeting measures to control these pathogens. The information obtained from analyses should be used as part of the food chain information (FCI).
