Biomedical Journal of scientific and Technical reviews 2017: Vo.1(5)Zoonoses caused by parasites constitute a large group of infectious diseases with varying host ranges and patterns of transmission. Their distribution, prevalence and transmission patterns are affected by the influence of both human and environmental factors. The economic and public health impact of such zoonoses warrants appropriate surveillance to obtain enough information that will provide inputs in the design and implementation of control strategies. A need therefore arises to regularly re-evaluate the current status of zoonotic diseases, particularly in view of new data available as a result of surveillance activities and the application of new technologies. Consequently this paper summarizes available information in Tanzania on parasitic zoonoses encountered in slaughter stocks during post-mortem examination at slaughter facilities. The occurrence, in slaughter stocks, of fasciola spp, Echinococcus granulosus (hydatid) cysts, Taenia saginata Cysts, Taenia solium Cysts and ascaris spp. have been reported by various researchers. Information on these parasitic diseases is presented in this paper as they are the most important ones encountered in slaughter stocks in the country.
