Research Program

Food safety is a defining issue in the global pork market today, and contamination with Salmonella and other foodborne pathogens is a major concern for the swine industry all over the world. Foodborne pathogens are being considered as another measure of overall pork quality, and a very challenging issue. For the industry to be able to respond to this challenge, sound knowledge about the ecology and epidemiology of foodborne pathogens is essential. Reducing the incidence and the societal costs of foodborne illnesses fundamentally requires more insight in the complex pre-harvest ecological and epidemiological system of these pathogens, including transmission and risk factors. The overall goals of our research line are to determine how production variables (such as common management practices and stressors) affect the risk of pork and pork products contamination with foodborne pathogens, and developing effective pre-harvest intervention strategies for reduction of these pathogens in market pigs entering the abattoirs.

Some specific objectives of our research line:

  1. to determine the effect of feed withdrawal and transportation on the susceptibility to Salmonella in market-age pigs,
  2. to determine the effect of feed withdrawal and transportation on prevalence and levels of Salmonella in market-age pigs,
  3. to develop and evaluate potential pre-harvest intervention strategies to reduce the prevalence and levels of Salmonella carried into the abattoirs by market pigs.
