ABSTRACT

The risk assessment concept was used to model the probability and consequences of human health risk associated with Trichinella in pork dumpling in Nepal wherein prevalence is low. The concept of sensitivity analysis was used to identify important factors in the production chain which may affect the risk for consumer infection. The model showed that without testing the pig carcasses for Trichinella, the annual risk of infection was 83 people in a million. Seven predictive factors highly correlated with risk including likelihood of consumption of pork dumpling, but the sensitivity analysis showed that within herd prevalence for backyard herd was significantly correlated to the risk of infection. This model can be used by the authority to communicate quantitatively the risk of Trichinella infection and the benefits of testing pig carcasses.
