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

Full Text PDF


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. Targeted population was 1,980 slaughtered pigs from those slaughterhouses and 90 pigs were randomly selected during the study period of January to March, 2012. A total of 270 muscle samples (tongue, masseter and diaphragmatic muscles from each pig) from 90 slaughtered pigs were collected and examined for the presence of Trichinella larvae by using artificial digestion method. Among the examined samples, three samples from three pigs (3.3%) showed Trichinella positive. Trichinella larvae were observed from two diaphragmatic muscles and one masseter muscle. In those positive samples, Trichinella 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. Among the hypothesized risk factors, the presence of rodents around the pig farm and type of feed (use of uncooked waste feed) were identified as associated risk factors for trichinellosis. Age, gender, body weight, rearing system and use of anthelmintics appeared no association with porcine trichinellosis in this study.
