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.
