Quantitative risk assessment of salmonellosis in Cambodian consumers through chicken and pork salad consumption

Salmonella is a globally important foodborne bacterial pathogen that poses high risk to human health. This study aimed estimate the Cambodian consumers from acquiring salmonellosis after consuming chicken and pork salad, using quantitative microbial assessment (QMRA). Chicken salads are typical dishes containing raw vegetables boiled meat or pork. As previously described, samples (n = 204 of each) were collected traditional markets in 25 provinces generate data on contamination. Salad preparation consumption practices surveyed 93 households this information was used design an experiment assess cross-contamination ready-to-eat salad. In part reported here, consumption, dose-response, predicted modeled Monte Carlo simulations at 10,000 iterations. The prevalence set 42.6 45.1%, respectively, with average most probable number (MPN) per gram 10.6 11.1 MPN/g, based earlier study. Half interviewed cooked for salad directly purchase. QMRA model showed annual both 11.1% probability illness person year (90% CI 0.0–35.1), 4.0% 0.0–21.3), 14.5% 0.0–33.5), respectively. factors influencing while preparing followed by market. wide confidence interval incidence mainly due variability reducing bacteria concentration cooking consumption. high, provides evidence supporting control measures improving safety retailed obtained food methods household.
