Survey of the Porcine Trichinellosis in Slaughtered Pigs in Nay Pyi Taw, Myanmar

Abstract

Abstract.A cross-sectional study was conducted to determine the prevalence and associated risk factors of trichinellosis in slaughtered pigs from three slaughterhouses located in Pyinmana, Lewe and Tatkon Townships, Nay Pyi Taw, Myanmar. A total of 270 muscle samples (tongue, masseter and diaphragmatic muscles from each pig) from 90 slaughtered pigs were randomly collected and examined for the presence of Trichinella larvae by using artificial digestion method. Three pigs (3.3%) showed Trichinella positive and larval intensity per gram (lpg) was 0.2. For the determination of associated risk factors of trichinellosis, questionnaire interviews to officials of slaughterhouses and owners of slaughtered pigs were conducted. The presence of rodents around the pig farm and type of feed (use of uncooked waste food) were identified as associated risk factors for trichinellosis. Porcine trichinellosis occurred with a low rate of infection in this study.
