Prevalence of porcine cysticercosis and risk factors for Taenia solium taeniosis in Funyula Division of Busia District, Kenya

Abstract

The prevalence of Cysticercus cellulosae in pigs was studied by antemortem lingual examination while the risk factors for Taenia solium taeniosis were evaluated by administration of a standard questionnaire. Antemortem lingual examination and palpation of 107 pigs of various ages showed that 15 (14%) had cysticercosis. Interviews of pig farmers in 72 households revealed that 98% allow their pigs to roam (free range) while only 2% tether their pigs. The tether ropes are weak and pigs easily break loose. There was no pig housing. Those households feeding pigs entirely on pasture were 89.6%, while 10% supplemented the pigs with fish waste (Omena) and brewers\'waste. Almost all the households (98%) had between 2–3 mature pigs. Fried pork was preferred by 85% of these households and 33% were practicing home slaughtering of pigs with no official meat inspection. Pit latrines were present in 83.3% of these households, which were used by adults. Pit latrines were lacking in 15% of the households while one household had a latrine, which was not used. Knowledge of Taenia solium taeniosis transmission was recorded in 37.5% of the households while 89.6% had previous tapeworm experiences. Those with active tapeworm infections composed 8.3% of the households. It was concluded that porcine cysticercosis is prevalent in free-range pigs in Funyula division. There is the possibility of Taenia soliumtaeniosis in human beings.
