Abstract
Food-borne diseases in general have received more attention in the last decade, but little attention has been paid to parasitic food-borne infections. This is probably due to the fact that they are not associated with acute illness as bacterial and viral infections do. In the Sudan, the most important parasitic meat-borne infections are Taenia saginata, Toxoplasma gondii, Sarcocystis spp., Linguatula serrata and fish infection with trematode metacercaria. Control measures used in the country to prevent infection with these parasites are through inspecting meat in slaughterhouses for cysticercosis. Toxoplasma and Sarcocystsis infections are not considered during routine meat inspection due to lack of techniques for detection of these infections. Prevalence of infection with these parasites in humans and livestock in all States of Sudan is not available. Methods for routine diagnosis, monitoring or recording of these infections are inadequate, or not existing, in most of the laboratories. Studies are required to establish seroprevalence in livestock and humans. There is an urgent need to monitor and control meat-borne parasites using new technologies such as serological and molecular techniques, health education and vaccination. Researchers are urged to participate and establish innovative ways and means to control these diseases.
Highlights
Sudan is rich in animal resources approximately 106 million animal units [1] such as cattle, sheep, goats, camels, horses, donkeys and poultry, with consider potentials in animal production
Meat-borne parasites are transmitted to humans by ingestion of infected raw, undercooked or seasoned meat and meat-derived products of animal origin
Adults L. serrata were found in the nasal passages of 56 and 47% of male and female dogs in the endemic area [48]. It is evident from the research conducted in meat inspection and laboratory examination that meat-borne parasites constitute health hazards
Summary
Sudan is rich in animal resources approximately 106 million animal units [1] such as cattle, sheep, goats, camels, horses, donkeys and poultry, with consider potentials in animal production. Animals can be infected with parasitic and microbial pathogens. Some of these pathogens can be transmitted to humans via consumption of infected meat and milk causing food-borne diseases. Meat-borne parasites are transmitted to humans by ingestion of infected raw, undercooked or seasoned meat and meat-derived products of animal origin. The most important meat-borne parasites are helminths such as Trichinella spp., Taenia solium and Taenia saginata or protozoa viz, Toxoplasma gondii and Sarcocystis spp. or arthropods such as Linguatula serrata. Fish meat can be infected with various parasites viz, Diphyllobothrium spp., Spirometra spp., Opisthorchis spp., Clonorchis sinensis, Gnathostoma spp. and Anisakis spp. In the Sudan, the major meat-borne parasites are T. saginata, T. gondii, Sarcocystis spp., L. serrata and fish infection with trematode metacercaria
