- Abstract
Background: Among the most important pathogens in pork is Salmonella spp. Salmonella contamination can occur at any stage of the swine production chain: from the raw materials for animal feed, farm, slaughterhouse, deboning room, processing centers, among others. On the farm pigs can become contaminated with Salmonella and stay in the mesenteric lymph being excreted intermittently when the animal is subjected to a stressor such as transport or grouping with many animals, the bacteria being excreted in the feces can contaminate other animals. Objectives: To determine the prevalence of Salmonella spp in carcasses, and mesenteric lymph nodes, in Colombian swine chain. Methods: Sampling was performed by proportional stratified manner and fixing the beneficiation plants, each of the participating departments (13), which cover 80% of the sacrifice of the country. Sampling was conducted over a period of five months. 3M™ Molecular Detection System (MDS) was used for the identification of Salmonella spp. Results: A total of 1243 samples were collected within thirty (30) processing plants where 786 and 457 channel samples were taken in mesenteric ganglion. The highest prevalence of Salmonella spp., carcasses was found in the department of Santander (72.9%), mesenteric lymph node for a high prevalence was found in the department of Huila (60%), however these plants have a low share in the domestic market. Conclusions: The prevalence of Salmonella spp, national channels were 11% and 29.1% mesenteric lymph nodes.
