Iowa State University Conferences and Symposia

The SafePork conference series began in 1996 to bring together international researchers, industry, and government agencies to discuss current Salmonella research and identify research needs pertaining to both pig and pork production. In subsequent years topics of research presented at these conferences expanded to include other chemical and biological hazards to pig and pork production.

Abstract

Pork products contamination during the slaughter process represents an important vehicle of Salmonella sp. dissemination to humans. It's urgent to develop rapid, sensitive and accurate methods that allow the detection of a large number of Sa/monel/a-positive samples, in order to control these risks efficiently and in a practical time. This study evaluates the suitability of Fluorescent In Situ Hybridization (FISH) method as a rapid screening tool for Salmonella sp. deteclton in pork carcasses, as well in some risk tissues (ileum, ileocolic and mandibular lymph nodes and tonsils), which could be involved in Salmonella contamination during slaughter process. For that, FISH was comparatively analysed with the labour intenstve reference microbiological culture method (ISO 6579:2002) whose results were previously published by the same authors.
