Abstract

Trichinella is a zoonotic food-borne parasite, distributed worldwide. Wild boars, dogs, cats and raptors are infected with Trichinella due to ingestion of carcasses and/or meat contaminated with Trichinella larvae. Humans are infected as accidental consuming of raw/undercooked meat with Trichinela larvae. Dak Lak province has favorable climatic conditions, pig raising methods and practices of local residents for the circulation of Trichinella. Currently, there is no information on the prevalence of Trichinella in the province, it is thus necessary to determine the prevalence of Trichinella in pigs in Dak Lak province. Ultilization of artificial digestion method for muscle samples collected from 835 captive and free-range pigs in Buon Don, Krong Nang and M'Drăk district, the results showed that none of the samples had the presence of Trichinella. However, the true prevalence of Trichinella infection in pigs in the province estimated ultilizing Bayesian approach was from 0.38 (95% CrI: 0.02 - 1.29) to 2.44% (95% CrI: 0. 12 - 9.23%. A highly sensitive diagnostic method should be ultilized to determine accurately the prevalence of Trichinella in Dak Lak province in the next studies.
