Isolation of Salmonella from the Mesenteric Lymph Nodes and Cecal Contents of Cull Slaughter Sows- Implications for Public Health

Abstract

This experiment was conducted over a four month period by sampling 200 slaughtered cull sows for Salmonella.

The sampling was to determine the presence of Salmonella in cull sows at a Minnesota slaughter establishment. The weight ramge of the sows was 300 to 400lbs.

Two samples of mesenteric lymph nodes and cecal contents were collected from each sow. Conventional methods, using enrichment and plating into selective media followed by biochemical and serological analyses were used to isolate and identify Salmonella serotypes.
