DOCUMENT DESCRIPTION

Objectives: To quantify the risk of salmonellosis in humans through the consumption of boiled pork in urban Hung Yen Province, Vietnam, using a quantitative microbial risk assessment.

Methods: We collected 302 samples along the pork value chain in Hung Yen between April 2014 and February 2015. We developed a model in @Risk, based on microbiological, market, and household surveys on cooking, cross-contamination, and consumption, and conducted a sensitivity analysis.

Results: The prevalence of Salmonella in pen floor swabs, slaughterhouse carcasses, and cut pork was 33.3%, 41.7%, and 44.4%, respectively. The annual incidence rate of salmonellosis in humans was estimated to be 17.7% (90% CI 0.89–45.96). Parameters with the greatest influence on risk were household pork handling practices, followed by…
