[Clandestine slaughtering in Tunisia: investigation on the knowledge and practices of butchers concerning hydatidosis].
Echinococcosis is one of the major parasitic diseases in Tunisia, accounting for a considerable public health problem. We propose in this work to analyse the behaviour of butchers and to evaluate its impact on the hydatic cyst transmission.


METHODS
We carried out a national transversal descriptive survey that included 97 butcher shops using illegal practice, located in 18 regions (governorats) of Tunisia. The sampling procedure was implemented according to the level of disease endemicity.


RESULTS
60.8% of butcher shops were located along main roads and therefore supplying travellers. Among the animals slaughtered sheep come in first position (97.9%). More than 80% of the butchers kept aside a place around the butcher shop to sacrifice their animals. We noted the presence of dogs near butcher shop in 52.6% of cases and stray dogs in 43.3% of cases. Only 13.4% of the butchers knew the disease mode of transmission. Parasitized viscera were thrown into dustbins or further in the riverbed in 56.7%. More than 50% of butchers, having an inadequate behaviour in front of parasitized viscera or ignoring the disease cycle, were originating from an hyper or holoendemic area.


CONCLUSIONS
Illegal slaughtering practices have an important impact on transmission of cystic echinococcosis in Tunisia.
