Technical Abstract: Approximately 12000 samples (54000 ileocecal lymph nodes from slaughter pigs and 6600 diverse environmental material such as feces, feed, dust, soil and water from swine farms) have been cultured for Salmonella since 1997 in the framework of the long-term research project "Salmonella Abatement in the Pork Chain" at the University of Minnesota. More than 800 isolates were serotyped. For 343 isolates from 4 Minnesota swine farms (77 lymph node isolates, and 266 environmental isolates), the antimicrobial sensitivity patterns were determined in the framework of the USDA/FDA National Antimicrobial Resistance Monitoring system (NARMS) at the USDA:ARS Richard Russell Research Center in Athens, Georgia (1). The presented paper reports the results of the serovar identification of all Salmonella isolates and the results of the sensitivity testing of the isolates from 4 selected (one with a high, two with a medium and one with a low Salmonella prevalence) Minnesota farms, comparing the isolates from the slaughter hogs (ileocecal lymph nodes) and from the corresponding environmental samples (feces, dust, soil, feed rodent droppings, water etc.).
