Abstract
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.
