RESUMO
BACKGROUND: A number of studies document the prevalence of Taenia solium infections in Nigeria, yet these studies do not cover porcine cysticercosis in private home slaughter slabs where there is no routine meat inspection and backyard pig keeping, slaughtering and sale are common practice. METHODS: An environmental and sanitary assessment was conducted within two unregistered home pig slaughter slabs in selected parts of the Kaduna metropolis in Nigeria. Slaughter premises were inspected for availability of basic facilities and questionnaires were used to elicit necessary informative data. Butchers were examined for taeniasis by stool microscopy and copro-antigen enzyme linked immunosorbent assay (copro-Ag ELISA) to ascertain T. solium - taeniasis. Pigs slaughtered at the premises were examined for cysticerci. RESULTS: Home slaughter conditions were substandard, unhygienic and lacked the basic facilities of a proper slaughterhouse. Prevalence of porcine cysticercosis was 9.3%. The butchers participating in the study had very poor knowledge of T. solium infections and 30% tested positive for taeniasis by copro-Ag ELISA at the time of the study. CONCLUSION: Home slaughter of pigs in the areas studied should be considered and integrated as a component of prevention and control programmes - particularly through educational interventions - in order to equip individuals involved with a good understanding of the risks associated with animal husbandry and human practices.
