UNASSIGNED: The aim of this survey was to obtain data on microbiological contamination of @entity1707 carcasses and environments in three large-scale Italian slaughterhouses (identified as A-B-C) located in Northern Italy. Each slaughterhouse was visited six times. Five carcasses and three different sites of the slaughterhouse (before and during slaughter) were sampled on each sampling day. A single pooled caecal sample was taken on each sampling day. A total of 90 carcasses, 108 environmental samples and 18 caecal samples were collected. Samples from @entity1707 carcasses and slaughterhouse environment were analyzed for total viable count (TVC), Enterobacteriaceae count (EBC) and @entity5746 . The caecal contents were examined for @entity5746 . Carcasses from slaughterhouse A presented the greatest TVC and EBC mean log value, whereas environmental samples collected during slaughter activities from slaughterhouse C showed the greatest TVC and EBC mean log value. As far as the environmental samples collected before slaughter activities are concerned, an average up to 6 log10 colony forming unit (CFU)/cm(2) TVC in two slaughter plants (A and C) and 5 log10 CFU/cm(2) TVC in one slaughter plant (B) was detected. @entity5746 was recovered in two slaughterhouses (A and B). Four different @entity5746 serotypes were detected in the positive samples (11). Within serotype S. Rissen and @entity2491 monophasic-variant isolates, two pulsed-field gel electrophoresis patterns were identified. The findings in this survey suggest that carcass contamination is influenced by the slaughterhouse plant and this could be a result of differences in line speed. The results of environmental sampling have not shown an association with the slaughterhouse plant.
