authors (Buncic et al., 1991 [49]; Ripamonti et al., 2002 [50]; Kanuganti et al., 2002 [41]; Autio et al., 2003 [51]; Fabbi et al., 2005 [52]) correlated the contamination of equipment and consequently of the carcasses with the presence of the pathogen in other niches, such as the tongue (14%) and tonsils (7%–61%). This wide range of prevalence is probably due to differences in sampling techniques and/or methods of farm management.
