Inoculation of Weaned Pigs by Feed, Water, and Airborne Transmission of Salmonella enterica Serotype 4,[5],12:i:-

Salmonella enterica serotype 4,[5],12:i:- (STM) has become an increasing problem for food safety and been often detected in pork products. For this study, weanling pigs were exposed to STM-contaminated feed, water, or air determine possible STM transmission routes. An uninoculated control group of was included. The monitored daily feces rectal nasal swabs. colonization most prevalent tissues from tonsil, lower intestine, mesenteric lymph nodes. No differences lesion severity observed between inoculated pigs. Contaminated aerosolized particles caused infection weaned pigs; however, no skeletal muscle destined human consumption. Based on the results contamination products likely cross-contamination meat by digesta node tissue during processing.
