Abstract

There was a significant direct correlation between the presence of Salmonella in ileocecal lymph nodes and the titer of antibody to Salmonella in meat juice. It was also demonstrated that there is no significant correlation between titer of antibody in serum collected from pigs immediately prior to slaughter and the presence of Salmonella in the feces on the floor of pens. These conclusions suggest that the level of antibody to Salmonella in meat juice can be used to determine whether or not groups of pigs at slaughter contain Salmonella in their ileocecal lymph nodes.
