A possible association between Salmonella enterica and Ascaris suum was investigated. Salmonella infection was measured by antibodies in meat juice samples taken at slaughter, expressed as an ELISA OD-value. Ascaris infection was measured as the presence of white spots in livers detected at slaughter. Data were collected in Denmark in 2001, comprising 128.316 finishers. There was a significant qualitative association between presence of Salmonella antibodies and presence of liver spots at herd level. In contrast, no significant quantitative association at herd level was found. Pigs with liver spots had lower antibody levels against Salmonella compared with pigs without white spots. However, despite the significant association between Salmonella and Ascaris at herd level, its causality remains to be determined.
